BMW Shimmy / Wheel Wobble - Fixed in 10 minutes!!!
HTML-код
- Опубликовано: 9 июл 2024
- I hate shimmy! The BMW E31, E32, E39 and the E38 7-Series can all suffer from the dreaded 'shimmy'. This is a left-right shake through the steering wheel between the speeds of 45 MPH - 55 MPH, the speed range is important, other things wobble at different speeds, but shimmy is in this speed range. It is also important to say that shimmy is a front axle problem, this is because 45-55MPH is the resonant frequency of the Power Steering System. Wheel wobble is very different to shimmy.
More about Shimmy: www.meeknet.co.uk/E31/E31_Shi...
The shimmies are often an indication of general wear in the steering system and suspension (but not always), the BMW E31 has a great deal of weight over the front wheels, especially when braking. But don’t be fooled, there are often simple things you can do to fix it rather than replace suspension components. Most importantly, shimmy always starts with wheels and tyres - they are the cause of shimmy - replacing the other bits just hides it!
We will go through them starting with the cheap things (which often are all that are needed) - so, let’s get on with it - but don’t forget we are dealing with steering wheel wobble between 50-60 MPH - other wobbles at other speeds have other causes!

You are an 8 series Godsend !
I can not express my gratitude enough for your e31 knowledge. Please continue to educate those of us who appreciate the wonderful car that is, the E31.
Your website is my replacement owner’s manual. It has helped me COUNTLESS times. NEVER take it down...please.
That's very kind of you - thanks!
@@TimmsBMWRepairsandInformation I have owned a 1995 BMW 840ci for 10 years, recently when punching the car to accelerate there would be a brief hesitation and then it would accelerate. This happened a few times, and then the car would be hesitant to start. Now it will not start at all. Timm, what is the issue? No one knows these cars better than you, please help!
@@TheHomeExpert5 Sorry, missed this a year ago - hope you have it sorted!
@@TimmsBMWRepairsandInformation no, it's still not running, headed sitting in the garage. Do you have any ideas?
@@TimmsBMWRepairsandInformation Where is the fuel pump relay located??? I cannot find it...
Oh, my life - I thought something was seriously wrong with mint E46.
The wobble was so bad, I thought the wheels were going to come off.
You are an absolute hero - fantastic video, well done!
Glad it helped Chris!
You sir, are a bloody genius.
I have been chasing this issue in my Z3 since having new tires installed not long ago. I just increased to 39psi cold, and tested with significant difference. THANK YOU!
Another happy customer! Glad it worked out for you - it really does work!
I was a mechanic and you know they did not teach us about Dynamic imbalance, only s Static, thank you for sharing your knowledge. Cheers and Merry Christmas ,.
Thanks John, and the same to you!
Timm I've only just found your RUclips channel after years of consulting your excellent website. Your expertise and eagerness to share your knowledge have made ownership of my E38 so much richer! I cannot thank you enough sir!
Thanks Leon!
Brilliant advice, just got finished overhauling my belts, pumps and tensioners - got back on the road to dreaded shimmy! - 42psi in all 4 wheels and now fixed! Thanks again Tim, can't thank you enough for all the great and free advice on these cars.
Nice work Ed!
Ok so I went up from 35 to 41psi. The moment I hit the gas pedal on the Highway I smiled from ear to ear. No more SHIMMY!!!!! I cant believe after 2 years of FRUSTRATION and embarassment all I had to do was added 6 more lbs of Pressure. The crazy steering wheel shake is GONE.
I Thank you for the time you have spent to figure rhis out and for spreading the knowledge. So many people keep good info to themselves but you did rhe right thing. Much appreciated!
That's great news Dave - so glad it worked!
Greetings from across the pond. Watched this last night and this morning inflated all tires on my E28 to 42 psi. I'm running E39 17" style 5 BBS wheels 235 mm wide tires. This car always had shimmy or what's called here death wobble regardless of what suspension parts were replaced. As of this morning no more shimmy. Brilliant!! Thanks Timm!
That's great news Michael!
Another fascinating video by the one and only Dr BMW...
My E38 750il had this problem and I spend a bucket load of cash replaying every steering and front suspension part.
Thanks
Always my pleasure!
In my case the whole car started vibrating randomly and it freaked me out not knowing what it could be or how much it would cost to fix but this video has calmed my mind. Thank you Timm!
Blimey, it can be scary!
This video is what I have been looking for about 2 years. Finally someone has a clue what could be the problem. My 01 E38 iL has the wobble of DEATH it starts at 54mph and stops at 60mph. It has literally driven me INSANE to say the least! I am rolling on STYLE 32 rims with 255 35 20 up front & 275 30 20 in the rear with 35 psi all around. I have tried everything. From tie rods to hub centric rings and I want junk the THROPHY winner because of this shimmy. I'm hoping when I go up to 41 psi it fixes the issue so I can have some enjoyment driving this beauty again. I will be back to give you and update shortly.
Thanks in advance. My fingers are crossed!
How did you make out after increasing tire pressure? Wondering if that fixed your problem.
Dave has replied today - problem fixed!
dave..did you inflate all of yours tyres to 41psi, if so, did solve the wobble?
Sir you are a genius!!!! I was out of ideas and hope until I found your video. Went to lot of repair shops but couldn't find the cause of this shimmy and it was driving me and everyone near me crazy:))). You sir are a life savior. Thank you so much.
That's brilliant news - glad it was this simple problem
On another topic sir.... I am looking into installing LPG on my E39 520i because of the increase in petrol price but I am getting mixed news. Some people say it's very good for the engine while some other people say not to do it. Do you happen to have any experience with LPG? Your opinion will be highly valued. Thank you sir.
Nice video, made me rethink about the "shimmy" problem on my E46 Compact:) Also, nice car-color style;)
Thank you!
Brilliant video! Good detailed information and decent editing made for a good watch! Will be subscribing
Glad you enjoyed it!
i have had 5 7 8 series bmws for the last 30 years and have tried to fix this problem on all those cars ,. never understood this until you explained it timm . you sir are a steely eyed missile man :)
I'll take that! Thanks!
@@TimmsBMWRepairsandInformation your welcome :)
Hi Timm's, my brother just bought 840ci and vicious wheel wobble suddenly occured, thanks to this video the problem is now totally cured, many thanks and appreciation of your videos, mebbo
That's great news!
Mate you dont realize how much you have saved me. I have e39 540i/6 M sport with the parallel wheels and 530i/5 sport and both had the shimmy steering. I was just about to do a complete suspension overhaul but today i took the 540 and added the air to 40psi and 42psi at the back and its like magic...its gone i now can enjoy my M5 wanna be without M5 issues 540i without the shimmy... thank you mate owe u a beer
That's great news, well done for trying it!
Great video, I was looking for an explanation for the steering wheel vibration im my w204 attended a lot of videos on youtube just to understand more about the causes and possible solutions before I take any step to avoid changing any unnecessery parts... and no one explaned it with a detailed easy to understand as you did.... thank you for sharing this and now I know where to start... tyres and wheels!
Glad it helped
Loved the step by step breakdown. Keep it up mate!
Thanks!
I have 48 years of BMW experience and this is a new one to me.
Always like to give out unique advice! Check out the comments below - this has helped a lot of viewers
Great explanation , had never heard of Dynamic imbalance before. I'm a E39 owner, so all of your hints and tips are very welcome :)
Subscribed.
Thanks!
omg i followed your advise and the wobble is actually gone. Before i commented i took your advice went to the station went 40 psi all around and its crazy how it actually work thanks so much. Its a simple problem but we often overcomplicate the solution little did i know it was just air in the tires. You saved me a fortune!
Thanks for letting us know, and that's great news! SO many people don't believe this makes a difference!
And further to my last comment. I pumped up all 4 tyres to 40 psi, and hey presto the wheel wobble has gone! Almost can't believe it was something so fundamentally simple. Thanks again!
Another happy customer! Pass the word on as everyone should try this first!
Thanks very much! Was trying to diagnose this on my 2000 Z3 Roadster, this makes sense. Going to try pumping my tires up a bit from 33psi to maybe 40.
Let us know how you get on Kaden!
Timm you’re a genius! Thank you for saving me a fortune! 👍😀
Always my pleasure!
Amazing as always. Great information and tips :)
Thank you very much!
Thank you all your great content.
Really helped me with my 650.
Top man
Great to hear!
A have a very slight shimmy @ 70 mph on my F07, because this is above the 45-55 mph mark you mentioned here, where do you think my shimmy comes from? Thank you for an excellent and informative video!
I have fully fired the parts gun at my e36 replacing every front end suspension component (no regrets promise) to try and resolve this exact issue, still present so will be trying this tomorrow! Hopefully it works. Subscribed as the knowledge you hold is deffo worth being apart of!
Let us know how you get on Dylan!
@@TimmsBMWRepairsandInformation unfortunately it did not solve the problem, did make a small improvement but I believe I have a bad steering rack. Still great tips tho😁
@@DylanE36 did you solve the problem as I’m having the same problem on my bmw e46 coupe
@@dirtydisco4x429 so even after a new steering rack I still had the issue, I’ve now converted my rack to none power steering. I was running 10j wide wheels and I believe the tyres had been fitted incorrectly as the heavy part of the tyre was fitted inline with the valve leading me to have to have lots of wheel weights. Got a friend at a tyre shop to put new tyres on and the wobble got better. But because the wheels where so wide any small unbalance or worn bush on the car really showed. Now running some better fitting wheels and good tyres and the issue was again even less noticeable. So I turned my attention to the steering shaft bush this was quite worn so I fitted a solid steering wheel bush (aluminium) and the issue has completely gone.
Another great video Timm.
Thank you!
Very informative as always keep it up 👍
Thank you very much!
Thank you very much for that detailed explanation.
Glad it was helpful!
Yet another great vid... Thanks again for your knowledge and knowhow.👍👌
Thanks!
Oh, you are good, I mean goooood!. This fixed the issue on my E39 touring.
Really glad it helped! Shimmy is difficult to fix sometimes!
It worked for the most part on my 94 e32 I got tie rods and some other components to swap out but it helped thanks again Timm
Glad it helped!
Great and very informative video. No one explained in details as much as you did. My question is, what about defective new tyres being out of round, will that cause a tyre shimmy or is it only a wobble related issue?
Unless you buy dodgy tyres, all new tyres are measured for roundness and dynamic balance!
I put it down to scuttle shake but your video has explained a lot i lack the precisness that you are explaining i also have uneven tyre wear but was always told by my mechanic to run my tyres at 33 but he also told me that five speed diffs on my 6 speed e53 auto were ok
Is it safe to add more psi to the tire? I mean 30 to 41 is pretty much
Thanks Timm. Looking forward to you vid on spacers.
Thanks!
Thanks mate. Another great video
Thank you very much!
THANK YOU SO MUCH. MY LEXUS HAD BEEN DRIVING ME NUTS TRYING TO SOLVE MY SWAYING AND BOUNCY RIDE. I WOUND UP CHANGING ALL OF MY BUSHINGS, SWAY BAR LINKS, AND REAR TRAIL ARMS AND STILL HAD A HORRIBLE UNSTABLE RIDE. MY TIRE PSI WAS AT 30 POUNDS. I BUMPED MY TIRE PSI UP TO 37 PSI AND ITS DRIVING LIKE A NEW CAR AGAIN. THANK YOU
My pleasure and glad it worked!
Going through the same thing , this will help? It feels like it’s my front left tire tho
@@Kevinmassinburg97 did you fix it?
Fixed my 640 Grand tourer speed wobble. Now it drives as nicely as it looks. Thx
Brilliant! I love to get feedback on these video's - especially where something helped - good on you!
Just tried this on my ‘98 E38. Perfect. Thanks.
Glad it helped
Great and informative video. I learned a great deal about static vs. dynamic balance.
. Is 41 psi for all 4 tires regardless if one has a staggered setup with different width and size? 255 up front and 285 rear?
You can run 42psi on all four wheels - 255 at the front is very susceptible to shimmy!
I'm only 2 minutes in and the vibes in this video are brilliant
Thanks!
@@TimmsBMWRepairsandInformation where are you based chap. Love your knowledge
You have a very very beautiful car. Great information too. 👍
Glad you liked it!
This makes so much more sense now, i live inna mid west, the weather is always bipolar so one day im driving and no shimy, the next day its wayyy colder and all of a sudden that shimy got god awful now i know that the cold air prob lowred the psi and made the shimmy worse
Brilliant.
Thanks a lot Timm
Thank you very much!
I have an E90 325d which seems to experience "shimmy". I've tried 42psi but no luck... Between 50-60mph it is most prominent BUT, is made so much more noticeable on gentle to moderate braking... I've had wheels balanced, all tyre pressures sorted and 2 garages look for any mechanical issues underneath... Few worn bushes but nothing they think will cause the issue and run out is only 0.04mm so in essence... Nothing!
I refuse to accept that the car is "fine" when it is not something it should be doing and it never used to. It just started one day.
Any suggestions? It is driving me crazy!!
Shimmy does drive you crazy! If the shimmy is severe it can be a brake calliper dragging - check if both front wheels are at the same temperature after a drive, the centre of a wheel gets quite hot if a brake drags. The full list of possibilities are here: www.meeknet.co.uk/e31/E31_Shimmy.htm
just got a new sub right there. Bought a 2004 e46 today and the ONLY thing wrong with it is that weird shimmy at 50-60 mph. Everything else was perfect.
Let us know how you get on Chase!
Funny, I’m glad I watched this video, i started to get a slight shake at higher speaks around 90-110km/h in the front I have 235/40R19 on my e46, passenger front tire due to a suspected rim leak had dropped down to 29 psi, and I had a pretty decent shake, at first I was confident it was the lower control arm bushings, went to fill it up and go grab some bushing from the local store, and on the way the shake was gone I was mind blown how much a difference having around 35 psi makes compared to 29 on wider tires for the front !
Glad it helped, it makes a huge difference on wide tyres!
Hi Timm, on an e63/64 could this cause issues with Driving Assist? I know my tyres are off balance as one is wearing on the outer rim (although due to change soon) although I've found on a few occasions when I start the car (especially when the tires are on different levels) recently that a Driving Assist error comes up and someone times doesn't work at all until I start driving. The BMW garage have suggested a new Power Steering rack but I'm wondering if it's actually something to do with what you're discussing here.
It would seem unlikely - but I would doubt if it is the steering rack - they either work or the don't!
Brilliant, can you also share the steering wheel details? I'd love to upgrade from the ugly stock e31 steering wheel. Thanks Mate!
Thanks! Steering wheel all explained here: www.meeknet.co.uk/e31/wheel/E31_Steering_Wheel_Swap.htm
Thanks for the demonstration! My car has an intermittent shimmy, which I think is beside the fact that it's a convertible that's prone to cowl shake. I notice the shake, at times, even on quite smooth roads. I currently run the tires at 32PSI, but I suppose it couldn't hurt to bump them up some - maybe 38PSI. A wheel balance, too, would be wise of me to do, considering the set I picked up are well used.
Glad it helped, let us know what happens!
The rear suspension consist of the lower a arm and upper bushing or bearing ? If this parts go bad it’ll cause the e31 rear hub to have play like a bad wheel bearing at 12 and 6 o’clock. Are these parts hard to replace ?
There's a darn sight more bushes and joints than that: www.realoem.com/bmw/enUS/showparts?id=EF82-EUR-11-1998-E31-BMW-840Ci&diagId=33_0198

@@TimmsBMWRepairsandInformation Great, Thanks!
Im running 32 psi on my 650 and i get that exact problem i know one of my rear wheels has a slight ding in wheel but i do have a full car shake im going to try the higher pressures see if it works
Did it work Paul?
Hi Tim,
I drive 19" Styling 95 on my E39 with 235/35 and 265/40. I now have 2,5 and 2,5 bars in it. What do you think, is that ok? Its an 540i.
Yes, that's fine - only puff them up higher if you have shimmy!
Love that classic 8 series !!
Thanks!
Hi timm, just like to say a big thank you for the video. I had the dreaded shimmy on both my e38 740i and my 840ci I've got 19 inch alloys on both them I put 41 psi and shimmys gone, thanks again
Great stuff, I love hearing back when something works!
Great job at explaining
Thanks (belatedly)!
I have a 2014 w212 e350 4 Matic I bumped my tire pressure up and the ride has improved greatly 👍 before it was really shaky and unstable
Great stuff - you wouldn't believe how many shimmies this simple trick fixed!
I have shimming also in bmw 730 service told me that flat tire causing vibration and I need to change tire. If I make Rear tire 41 psi without any change on other tires will it cause some another problem or alarm ?
You need the front pressures to be equal to each other - the same at the back
i’m having the same problem aswell but once i’m off the gas the wobble/shaking is gone but once i get back on the gas it’s back again ?? could this be tore and wheel related aswell
If you get a wobble that is only noticeable in 5th gear when you have your foot on the throttle it is almost always due to a single-cylinder failure on the engine. The lack of a single cylinder on a V8 is not that easy to spot, the power is a bit down and the tick-over is a bit lumpy but V8's are prone to that anyway. It is most noticeable when on the flat at about 70 MPH when accelerating. The wobble goes immediately the throttle is lifted. A check of the sparkplugs will show 7 white plugs and one oily one!
Thanks a lot! Very helpful.
Thanks Frank!
This was brilliant. Haven't tried it yet on my BMW, but you explain so well that I feel able to check if this is the cause of my issue. Thank you so much for taking the time to explain.
Thanks Coka, from the replies below it has been quite successful!
I keeped getting out of the car thinking I had a flat 😅
It's a horrible feeling that's for sure!
I have an e38 2001 740iL it shakes at that same speed could it be the steering angle sensor needs to be reset?
No, the steering angle sensor will have no influence on the problem - more details here: www.meeknet.co.uk/E38/E38_Shimmy.htm
Hi
Great tutorial.
I have an E63 with a wobble in the steering between 55 and 60mph. I’ve replaced control arms upper and lower on the front but it’s still there. I’ve got 275/35R19 100 Y on the rear and 245/40R19 98 on the front with the recommended tyre pressure of Front 33Psi and rear 34.5 PSi.
Would you recommend that every tyre is inflated to 41PSi to remove the shimmy and if it does go would you recommend running them at that pressure as normal. Many thanks.
I certainly would - you've changed half the front suspension without any luck so I would start by inflating to a higher pressure (check the sidewall for maximum inflation) and see if that makes a difference - if it does I would suspect tyres as being the root cause. It is worth saying that tyres can be significantly damaged by shimmy!
Timm's BMW Repairs and Information many thanks
Tried to pump up my tires to 2.9 bar. What it did ? Steering wobble is now more noticable in higher speeds and it was a bit softened. When going straight, steering wheel is not moving 0.5cm right to left but i can still feel something is kicking into steering wheel when i turn it a bit to the right or left while keeping constant speed. I tried to do 4km distance without braking at night and slowed my car to 0km just with engine braking and all brake discs are hot (i can keep hand on them) but rear brake disc behind the driver seat is noticably hotter - cant keep hand on it . Not sure if that can cause steering wobble.
I think you are getting somewhere - more info here: www.meeknet.co.uk/e31/E31_Shimmy.htm
Hi Timm, I get severe steering wheel vibration when light to moderate braking is applied from 60mph to 40mph. If i brake hard then no vibration.. Any ideas? tyre pressure 38psi - could it be control arms?

hello Tim, i have an e61 with 245-40-18 rear and front tires and i was just about to do the front suspension overhaul because of the wheel wobble, but thanks to your video i pump the tires today to 39 psi and the wobble ist almost completly gone. cheers mate!
Excellent, good to hear it!
Pumped to 260 psi and the shimmy seems gone now.Will increase to 280 psi if its still there.Wait for the highway trip soon..Thanks to you for this video.
Possibly 260psi is a little high, but, don't let me spoil the party!
Will this work on a 2014 328i BMW?
Give it a try and let us know!
Hey I put 42 pSi didn’t work for me unfortunately, just put brand new tires and non oem wheels and 15 mm spacers in the front. Did force balance on my front tire’s nothing works for me :(

I have a 2006 BMW E60 550i and it doesn't have shimmy at any lower or high speed. But the front wheels shimmy only when I start breaking from a high speed coming to a complete stop and it causes the steering wheel to move left and right like crazy.
That sounds like a brake caliper problem, have a read of this: www.meeknet.co.uk/e31/E31_Shimmy.htm
@@TimmsBMWRepairsandInformation I appreciate your help 🙏
I had the shimmer, pretty badly at around 75mph so did your recommendation, put the psi up to 42psi and boom shimmer is gone, well almost gone. On a sweeping bend to right on dual carriage way I notice the shimmer slightly
Glad it helped - it does sound like your tyres have a few problems!
Hi Timm,thanks for all the vids,my expansion tank BLEW UP the other day,and after ordering the Mehl one,your vid popped up on comparison and then the replacement/fix…timely ! (Timmely !) anyways,I tried the tyre pressure thing,and it’s made the shimmy worse,it previously only manefest itself upon motorway braking,but now it’s doing it on the way up through 50mph…weirdly,one of my wheels is way further back (offside) in the wheel arch than the other,I had a mechanic mate change a little arm that goes from the steering rack (I think) and this is when my woes started,is it possible that the part they fitted is handed,and they put the wrong one on ?…it’s all I can think,tge shimmy is that bad you can’t hold the wheel,and it makes you blind…cheers in advance,Joel Chester (the silver 97 840ci off the calendar,from years ago)
Thanks Joel. The front wheel placement in the arch IS different right to left. There have been long discussions why this is the case, but even the publicity photos show it!

My 2006 650i still shimmy
BMW dealer said my vehicle is in perfect condition, they think it’s my after market wheels.
Should I purchase bmw stock wheels ?? what do you recommend & suggest ? Please help !
As I say, wheels are always the source of shimmy - and after market wheels are the worst of the lot! Try and borrow some OEM wheels if you can - and at the very least make sure you have hub-centric rings or spacers fitted, the after market hubs will be 74.2mm and OEM are 72.6mm
Will do thanks a lot 👍
Great video well done, only disappointment is the title says fixed in ten mins but it took 18 min. haha just like 2 minute noodles that always takes 5 minutes to cook. lol keep up the good work
Thanks for that George!
this is why he put the video in fast motion in the beginning..lol
Would road force balancing fix the problem?
No, the tyre would still have dynamic imbalance!
Will this help with my ‘94 325i ?
Yes, it is the same for all BMW's but tends to affect those with wide, low profile tyres.
Wow this actually worked, went from hot 29psi to 34 hot and it fixed the vibration
It does work! This simple thing often gets dismissed as rubbish, but it is based in science and does work!
This might be my issue. I have a e90 with bigger rims and tires then stock. I’ve done my Axles and wheel bearings and all the other components are in good shape. I’ll be trying this fix tomorrow!
Well, what happened?
@@TimmsBMWRepairsandInformation it decreased the shimmy/shake a bit but it is still definitely there. I thibk my rim might be bent
I have the same issue for my 2001 e46. In the city its perfect shimmy is not as bad compared to the highway. Climbing up 60-100kph the shimmy/rattling becomes annoying and makes me feel like something bad might happen. Will try this thx
Let us know what happens!
Looking forward to the next video......
Thanks!
I drive a E39 525i Facelift, had the same Issues for MONTHS! many Workshops no one had a Clue. After putting 2.7 Bar or 39 PSI in all 4 Tyres. Problem is gone! Thanks
Glad it worked, it often does!
FORD have the exact same stearing shimmy from loose steering links
Thanks for letting us know!
Won't your tires wear on the center at that 41 lb
No, I still wear the outsides first!
Hi Tim where are you based?
South of England
@@TimmsBMWRepairsandInformation i have an e90 330d facelift with a rythmic vibration/knocking sound from the back. Had an upper arm done as there was a lot of play in the rear right wheel. Car feels more solid now but the knocking/vibration is still prevalent. Any ideas pls. Had rear propahaft donut done as the rubber was cracked. Some say it could be tyres? But would they cause the noise/vibration
I have two BMW sedans, an E38, 1996 yr with 86K that shakes minimum at 55 mph and a E34, 1995 yr, with 165K miles that shakes worst at 45 mph. After watching your video I believe the E38 is tires and will up the pressure to 42 and try it. The E34 have wide wheels and it shakes more at 45 mph, it also has shims on all four tires. I'm going to have the wheels checked for balance and also up the air pressure, hopefully this will work.
Let us know how you get on - and shims are quite often the root cause - more info here: www.meeknet.co.uk/e31/wheel/Fitting_replica_alloys_to_the_BMW_E31.htm
if all or some of the tyres are mix match, the tread are uneven, which will cause shimmy , vibration ,body roll...
Now BOTH my E38s shimmy, one only started AFTER I replaced the front upper and lower control arms with quality brand replacements. On my other E38 I have replaced everything but the front wheel bearings and steering end links. Still has a bit of shimmy from time to time.
It seems high, but I will try 42psi, as the shimmy is driving me crazy. I have M-parallels on both cars, but with different brand tires on each car, in stock sizes.
Let us know how you get on - but that certainly sounds like a wheel problem, are the alloys OEM and with the correct centre-bore?
@@TimmsBMWRepairsandInformation OEM M-Pars, on the first car I bought new tires, had them balanced, inflated them to 40psi, replaced the upper and lower control arms, center steering link, and steering arm. Also new Bilstein shocks all around. All quality components. The only things I have NOT tried are steering end links and front wheel bearings. I guess I will replace those next as there is nothing left to replace.
The second car has OEM M-Pars, wheels were balanced when tires were installed. it had no shimmy until I had to replace the upper and lower control arms. The steering center link was also replaced. Once the new control arms were installed, it developed a VICIOUS shimmy from 55-60mph that was not there before.
I have been trying to solve my shimmy woes for several years now. I have ALMOST eliminated it on the first car, second car still has it bad.
My latest thought is to try new front wheel bearings.
@@Ready72000 Don't forget that shimmy always starts with the road wheels and tyres - there's nothing else that causes the oscillation of the steering system. Worn components exacerbate the problem but wheels are always the source. For violent shimmy suspect the brakes - have a read of this: www.meeknet.co.uk/e31/E31_Shimmy.htm
@@TimmsBMWRepairsandInformation I noted that point during your discussion. Tires were statically balanced before installation on both cars. On both cars, the issue seems to be initiated by the right front. I guess I could try a dynamic balance.
@@TimmsBMWRepairsandInformation I have also replaced the driveshaft center support bearing and flex disc on both cars.
Awesome
Thanks!
Wonderful
My pleasure!
Is that a 840ci???
It is the 840ci with the M62 engine....
Good video btw my mum lives in that town and that road is terrible I know your pain I drive it every day either in my mini cooper or my bmw e60
I quite like the A3 even though it's quite busy!
@@TimmsBMWRepairsandInformation yeah is a good road all time its not busy
my E46 has shimmy at 100-140kmh, like you said replaced everything, new control arms, tierods, brakes, bearings, freshly balanced wheels. Will try to inflate them some more hopefully it helps
That speed range means the problem is on the REAR axle not the front - so you could be looking at half-shafts or some problem with rear wheel assymettery
@@TimmsBMWRepairsandInformation hmm it would make sense as rear is untouched, but why can I feel it through steering wheel?
@@TimmsBMWRepairsandInformation I inflated my tires from 2.5bar to 2.8 and its 100times better, almost not noticeable! great tip! ty
It could also be the coupler on e46
Your tyres heat up quickly on the road and the pressure will go up. I have found and it was always recommended by a tyre shop here in the US that 36 psi cold was perfect for driving control, economy and tyre life. 44 psi is considered maximum for car tyres so I would not start at 40 or higher.
