The most amazing thing about power steering to me is the simple fact that they always tend to be so reliable. Even when they do go out it usually takes a long time.

Excellent videos. You sir, gave me the courage and instruction to perform a complete timing belt and water pump service on my 1MZ-FE V6. So... thank you! I saved over $1500 that I would have spent at my Lexus dealer.
Your a great teacher. Your English is awesome. You are the first person that don't say "um" between words. I can really understand your video. Specially with your details description on each components and it's purpose. .
I retired from a Ford dealership. In old days we had to reseal power racks... I got really fast at it after doing a few. Great video and great explanation on the torsion bar input shaft.
I've been learning everything I can about cars for 15 years and never knew this. I had no idea that power steering was so complex. Thanks for making such a great video!
ew.. dude, you also use his underwear, he wouldn't be making an appearance holding the seat down right? I bet you're Latin, Latin moms use old underwear as cleaning rags. represent La Raza! LOL.
Hey bro I’m having some issues on my 2011 tc. 2 weeks ago replaced the outer tie rod on the right side and had it aligned this past Monday. I’m getting weird jerks to the right side it does not do it all the time but when it does I’m just coating on the freeway like 60-75 I press the brakes. A bit and it will also jerk real quick like almost pulse light and u can feel it on the steering wheel and from the right side as well would it be that the steering rack is messing up? Shit is scary when it happens 😩
speedkar99 I ordered new rotors for the front new pads and ew pads for the rear. See if that does anything and lastly I’ll replace the caliper as well maybe it’s causing the pad to stick and I’m experiencing what I’m getting. But I’ve noticed that if I’m not on the brakes as much it won’t do it vs being in stop n go traffic then it opens up for a while on the highway. Idk it’s strange I don’t get weird clunks or noises from the steering either
Been a mechanic for pushing 30 years now. Always had a pretty good understanding of what's going on inside a rack even though I never had one fully apart. This was a good video. In addition to being very informative, it was also good instructional lesson on how to use the proper tool for the job.
If it's worn there's not much to do since rebuilding it is probably going to be the cost of replacement...that is if you can get individual parts for it ...most OEMs sell it as a unit.
Awesome video!! I just found your channel and i think we’re similar in the sense that we’re very “resourceful” when we work on our machines and we aren’t afraid to tear them apart to see whats inside. Thats the best part about working on cars. There are so many parts working together and they’re all fascinating. i try to impart that enjoyment on friends when they get work out of me but it takes a specific person to understand and care about whats going on instead of just mindlessly throwing parts at a car to fix a problem - or worse yet, taking it to the dealer for something that otherwise would cost no more than the parts themselves, a morning or two on a weekend, and a pair of dirty hands.

Talk about Modern Marvels, it's truly amazing how engineers designed something as complicated as a "Rack and Pinion" steering system. Great Teaching Tutorial, Thanks !!
Good job. I have an ml55 amg 2000 I need to top off the fluid. After putting the seafoam trans tune in. Can any any power fluid be used? I don't want to spend the money on CHF 11S. I just need a little. Can I use prestone... .european?
I hope to get a reply. Would appreciate it. So I want 26x16 on 37s. But have stock tie rods. And the sway bars are shit... it's a 12 year old truck. Would installing a hydraulic steering rack and pinion help? I want to install proforged rods inner and outter
Very nice explanation. It deserves to be noted though, that when no torque is applied to the steering wheel, as in going straight down the road, there isn't any pressure in the system. Hydraulic fluid is flowing through the valve body, but not against any resistance. The pump and hydraulics are freewheeling, as it were. This is why you only hear a load come on the engine when you turn the steering wheel (like when parking, or other low speed maneuvering).
your directional statements around 3:10 are ONLY true for rear stearing systems. the opposite would be the case for forward steering system. just pointing out that there are in fact two types of systems out there.

One seal causes so many headaches. You would think they could come up with a double seal system, even a 3 seal system would do it but no. Then they sell after market trash power stearing units that FAIL after a short time. Are you kidding me!
EMERGENCY QUESTION.... After having all my shocks and struts and lower control arms and ball joints and sway bars and bushings and pretty much everything else to do with my front suspension suspension replaced as of a couple weeks ago will driving over one curb that was a little bit too high quite frankly the curb came out of nowhere and attacked my tire but regardless..will that cause my whole rack and pinion thing to break?? the whole thing all at once????😭😭😭😭
Nice explanation ! I am always amazed by the ingenuity of people who came up with this kind of stuff. Sadly my power steering is leaking a bit and has too much play. Can't find any reconditioned power steering racks where I live (I don't really trust one straight from a junkyard - I might install it and then it leaks too), also it is very tricky to get it out from the car (need to remove part of the exhaust and subframe). Maybe my old Nissan is ready for the junkyard. Sad :-(
Yeah steering racks are generally not an easy to replace item. If the leak isn't bad I guess you can give it one last try with stop-leak but that could take it's toll on the pump later.
After watching a video like this (which BTW is REALLY well done) I'm always amazed that a) people ever figured out how to put all that shit together in the first place and b) that it actually works. A car is basically a rolling Rube Goldberg machine.
I agree. I marvel and ponder that someone sat there and designed and mass manufacted things that we never see or take for granted ....and this car is 15+ years old!
Speedkar99, first off very informative video. I have a question and this has happened to me prior. Sometimes on the initial turn of the steering wheel, you come up against some pretty high resistance and you can feel it break free and then work normally. Usually when everything is cold. I've been told its a worn shaft and the seals are binding. Is that true? Just for my own info as a diyer. Thanks in advance 👍👍👍
Thanks, I’ve suffered terribly with bad racks, leaky, hard to steer, etc. Now I know more. Didn’t know those holes the fluid moves through were so small by the pinion gear. Easy to clog.
Love all of your videos very well explaind thanx for ur efforts and realy apriciate your brother for his contribution in form of his socks and underwear ...lollz.... keep sharing your knowledge with us. Thank you
+Muhammad Tayyab your welcome I'm glad you enjoy it. And yep I gotta thank my brother for all the socks and undies I steal, they work best to clean up greasy situations.
Did you say how inefficient the pump is due to the pressure being wasted by returning to the pump? That's how a hydraulic system works. The pump pressurizes the fluid, sends it to where it goes, and returns back. If there is a tank then it gets sent back to the tank. If there isn't a demand for pressure then it cycles through the pump, lines, tank (if you have one) then.back to pump. I dont think you can make it any more efficient without breaking the bank. But now we are in the dawn of e-power steering so this may be a thing of the past in a few more years.
Appreciate you grand master 🏆 Subscribed your channel. How about add some english script? So other country's people can easily approach your channel..? Just my opinion😁
Why do the seals fail and make the racks leak? What causes that.....my Alfa Romeo was part of a series of cars that were actually written off by leaking racks. I myself am on second hand rack number 3 and am very nervous about this one failing as well. Does anyone know more about why they leak?
Seals are made of rubber or hard plastic. ATF used in them tends to eat at seals as they harden over time causing leaks As things wear, leaks are normal.
Driving on an unpaved road makes some knuckling sounds in one of the front wheels (my father's audi a4) almost like bottle against bottle. Paved roads no sounds. Does this have something to do with the power steering device, if you perhaps might know that?
You made top educational video. Your comments and notes go directly to the point and answer all questions one would come up with through your presentation. Excellent video length and it is very satisfactory. Many thanks for you brother.
Great video. Just a quick question. What happens when we turn n hold the steering wheel to its extreme positions.( extreme left n extreme right). How is the pressure build up avoided?
This could have been a good video except that it was going at about 120mph .... should've slowed down so that I could follow what you doing and saying :(
Hey, can you please tell me if the city-mode on a car can actually destroy a steering column ? I was driving with city-mode ON and after a while a heard a sort of whistle only when i was turning right. I drove for one week with city-mode OFF and I can't hear that whistle anymore. So my guess, is that the city-mode affects somehow the steering column. Thanks !
@@speedkar99 No it's not hybrid. It has a button called city-mode, when pressed it looses the presure on the steering wheel, so you can easily use it - with just one finger lol. But I don't know exactly how it works, or if this feature will break something on the steering column if used regularly. I have an Opel Corsa.
That's a really great video. One more bit of information: The control valve actually lets the steering pump free-wheel by letting the fluid flow easily from input to output when you're not using the steering wheel, so it's not all that in-efficient. It doesn't put much load on the engine until you begin to turn the steering wheel, and the control valve then blocks free-flow of fluid and forces it through the steering rack piston. That's why the engine RPM (at idle) drops a little when you turn the steering wheel, and if you turn the steering wheel all the way against the stop, the rack piston stops taking more fluid which causes the pressure to rise rapidly until the overpressure relief valve in the pump begins to let the excess fluid bypass the control valve. That's the hissing sound when you turn the steering wheel all the way. Thanks for the great video! I enjoyed every second and I enjoyed the fact that every second had something useful in it!
@@speedkar99 Oh, I see what you mean. Although with electric, you have to consider it's pump - an electron pump - aka the alternator - and it has to be larger to handle the increased load, and it's always turning and always sending full voltage to the electronic control module, which wastes some of that power all the time. The larger alternator puts more of a load on the engine, all the time. (Yes, a larger alternator has larger core losses even when producing small currents. Look up core losses in generators.) So the increase in vehicle efficiency isn't as great as you'd guess. But sure maybe you can get a couple percent better mileage - which could save you a few dollars a year - but my guess is that your entire savings is gone when you then also take into account the greater cost EPS to start with, and the greater cost when it dies and you have to replace it, and the much greater chances of it breaking: It's a very complex system involving wires, semiconductors, electromagnetics, and a computer chip more complex than the one that first landed on the moon: The average rate of failure and average yearly cost of EPS repairs per thousand cars FAR exceeds that for engine driven hydraulic power steering, and this cost severely consumes the slight fuel savings brought by EPS. Hydraulics last an extremely long time, are very simple, and nearly bulletproof.
This person trying to explain the mechanism and place so much effort, persons who click "Dislike" have either nothing better to do or no technical knowledge.
Any idea, my car has usually a numb and heavier steering, then one day all of a sudden the steering got perfectly light and smooth for two days, before becoming numb and heavier again.. Changed the pump, the reservoir, correct fluid, steering coupler, ball joints, strut bearings, rack not leaking, pretty much everything checks fine. Not electrically assisted. Only the spool valve remains unchecked. Can the rotary valve do this?
I'd be interested to see what you find if you open the pinion valve, I've got a Volvo S80 with something similar, except the assistance comes & goes in a "twitchy" fashion depending how much pressure I put on the steering wheel. My thoughts were either dirt/sticking valve, wear in the joint of valve to pinion (the pin in this video) or possibly I thought the torsion bar could have fatigued after 194000 miles on mine but not sure.
@@danmackintosh6325 I am quite convinced now the system is clogged somewhere, perhaps at the rotary valve or at the line from the rack to the fluid reservoir. What is more, because of this restriction, the power steering pump is 'forcing' against the fluid, and this drains significant engine power. I am fully aware that this sounds strange but I come to think it's true. Of course, there is nobody else saying this anywhere on Internet. But here's what I did. This is entirely experimental and very unconventional. I lifted the front wheels off the ground, fire up the engine (transmission in P), then kicked at one of the front wheels with some force, both at 3 o'clock and at 9 o'clock. The reason for this I this will force the rotary valve to quickly open and shut, and perhaps this kind of 'kicks' into the debris that may be stuck in there, and may dislodge them a little. The result of this was very surprising. For one, once back on the road the steering felt like it was completely damaged: vibrations, kicks, shakes strongly. It never did that before. But then after some driving all this vanished and the steering become very light, but what is even more impressive is the engine power and sound, it felt just like the engine was back to it's young days again. My understanding is the strange steering 'kicks and shakes' were the result of something getting unstuck or unclogged. Unfortunately the light steering lasted only a few days. I'm repeating now this treatment. Again, after kicking the wheel the steering felt really scary, but that goes away within a day or two. I wish someone goes remove the rotary valves on these S60 and let us know how it looks inside.
Let me get this straight, your issue is on a Volvo too, an S60? That's interesting if so, seems a fairly common problem (still very uncommon mind, just more than on other makes). If I'm right, and yours came to you with red ATF/Dexron II instead of CHF for the fluid then it could be some reaction between the two types of fluid causing "clotting" in the valve.
LMAO @ "NEXT I'M GOING TO USE MY 19MM HEXAGON SOCKET"!!!!!!

Nice explanation ! I am always amazed by the ingenuity of people who came up with this kind of stuff. Sadly my power steering is leaking a bit and has too much play. Can't find any reconditioned power steering racks where I live (I don't really trust one straight from a junkyard - I might install it and then it leaks too), also it is very tricky to get it out from the car (need to remove part of the exhaust and subframe). Maybe my old Nissan is ready for the junkyard. Sad :-(
Yeah steering racks are generally not an easy to replace item.
If the leak isn't bad I guess you can give it one last try with stop-leak but that could take it's toll on the pump later.
After watching a video like this (which BTW is REALLY well done) I'm always amazed that a) people ever figured out how to put all that shit together in the first place and b) that it actually works. A car is basically a rolling Rube Goldberg machine.
I agree. I marvel and ponder that someone sat there and designed and mass manufacted things that we never see or take for granted ....and this car is 15+ years old!
Hey man this is by far the best video I’ve seen that explains how a power steering rack works. Great Job!!!!
Glad you enjoyed it
Speedkar99, first off very informative video. I have a question and this has happened to me prior. Sometimes on the initial turn of the steering wheel, you come up against some pretty high resistance and you can feel it break free and then work normally. Usually when everything is cold. I've been told its a worn shaft and the seals are binding. Is that true? Just for my own info as a diyer. Thanks in advance 👍👍👍
That sounds right, you should also hear clunking or feel play in the UV joints
Know cris fix? The editing and how you narrate it, its very similar. But despite this, very good job!. Keep doing this !!!!!!. Very good!!!!!
Thanks
Alot of people strike similarities
But I have my own style in content
In case of shaft, it is much better to cut piece with pin on the end.
Then you can disassemble everything almost without any damage.
Thanks
Good explanation. I knew in general how it worked but seeing the various pieces as you took them apart made everything clearer. Thanks.
+Russel Brooks Hey thats what I'm here for, thanks for the feedback.
Thanks, I’ve suffered terribly with bad racks, leaky, hard to steer, etc. Now I know more. Didn’t know those holes the fluid moves through were so small by the pinion gear. Easy to clog.
Make sure the seals are intact and the fluid is fresh ATF.
Love all of your videos very well explaind thanx for ur efforts and realy apriciate your brother for his contribution in form of his socks and underwear ...lollz.... keep sharing your knowledge with us. Thank you
+Muhammad Tayyab your welcome I'm glad you enjoy it. And yep I gotta thank my brother for all the socks and undies I steal, they work best to clean up greasy situations.
Did you say how inefficient the pump is due to the pressure being wasted by returning to the pump?
That's how a hydraulic system works. The pump pressurizes the fluid, sends it to where it goes, and returns back. If there is a tank then it gets sent back to the tank.
If there isn't a demand for pressure then it cycles through the pump, lines, tank (if you have one) then.back to pump.
I dont think you can make it any more efficient without breaking the bank. But now we are in the dawn of e-power steering so this may be a thing of the past in a few more years.
Variable pumps or electronically actuated pumps may be more efficient
4:00 What kind of seal are the 4 green seals ??
Appreciate you grand master 🏆
Subscribed your channel. How about add some english script? So other country's people can easily approach your channel..? Just my opinion😁
Good idea. Thanks
Please teach us how gear change happens in transaxle...??.. I want to know how two cables change 5 plug one reverse gear... It s very confusing...
+TheRouteShow I'd love to do manual tranny but mine is automatic
i have searched everywhere and i am never able to get a video to understand the above question..please make one..
Why do the seals fail and make the racks leak? What causes that.....my Alfa Romeo was part of a series of cars that were actually written off by leaking racks. I myself am on second hand rack number 3 and am very nervous about this one failing as well. Does anyone know more about why they leak?
Seals are made of rubber or hard plastic.
ATF used in them tends to eat at seals as they harden over time causing leaks
As things wear, leaks are normal.
Driving on an unpaved road makes some knuckling sounds in one of the front wheels (my father's audi a4) almost like bottle against bottle. Paved roads no sounds. Does this have something to do with the power steering device, if you perhaps might know that?
That sounds like strut mounts
You made top educational video. Your comments and notes go directly to the point and answer all questions one would come up with through your presentation. Excellent video length and it is very satisfactory. Many thanks for you brother.
You are welcome. Thanks for your kind feedback
yeah, really concise, love it.. not too quick as you can always hit rewind.. no bullshit waffle. love it!!
That's my style. Thanks
Great video. Just a quick question. What happens when we turn n hold the steering wheel to its extreme positions.( extreme left n extreme right). How is the pressure build up avoided?
It's short circuited back to the reservoir
Those must have taken a while to cut open with a grinder! How many discs did you go thru?
+vVeazel I think I burned through at least one disc for this project
Thank you for the great description of the power steering system operation.
Glad it was helpful!
This could have been a good video except that it was going at about 120mph .... should've slowed down so that I could follow what you doing and saying :(
RUclips has a slow motion playback option lol
Hey, can you please tell me if the city-mode on a car can actually destroy a steering column ? I was driving with city-mode ON and after a while a heard a sort of whistle only when i was turning right. I drove for one week with city-mode OFF and I can't hear that whistle anymore. So my guess, is that the city-mode affects somehow the steering column. Thanks !
I have never heard of city mode. Is your car a hybrid?
@@speedkar99 No it's not hybrid. It has a button called city-mode, when pressed it looses the presure on the steering wheel, so you can easily use it - with just one finger lol. But I don't know exactly how it works, or if this feature will break something on the steering column if used regularly. I have an Opel Corsa.
Good, precise and cogent description of how rack&pinion assembly works without being over technical. Thanks 99.
Glad you enjoyed it
Brilliant video, thank you. I'm amazed that you don't feel the slack in the steering resulting from the torsion bar twisting.
You are welcome.
No you won't feel that slack because of the steering ratio
That's a really great video. One more bit of information: The control valve actually lets the steering pump free-wheel by letting the fluid flow easily from input to output when you're not using the steering wheel, so it's not all that in-efficient. It doesn't put much load on the engine until you begin to turn the steering wheel, and the control valve then blocks free-flow of fluid and forces it through the steering rack piston.
That's why the engine RPM (at idle) drops a little when you turn the steering wheel, and if you turn the steering wheel all the way against the stop, the rack piston stops taking more fluid which causes the pressure to rise rapidly until the overpressure relief valve in the pump begins to let the excess fluid bypass the control valve. That's the hissing sound when you turn the steering wheel all the way.
Thanks for the great video! I enjoyed every second and I enjoyed the fact that every second had something useful in it!
I meant it's still inefficient compared to electric steering, since you still have the pump and fluid circulating
@@speedkar99 Oh, I see what you mean. Although with electric, you have to consider it's pump - an electron pump - aka the alternator - and it has to be larger to handle the increased load, and it's always turning and always sending full voltage to the electronic control module, which wastes some of that power all the time. The larger alternator puts more of a load on the engine, all the time. (Yes, a larger alternator has larger core losses even when producing small currents. Look up core losses in generators.) So the increase in vehicle efficiency isn't as great as you'd guess. But sure maybe you can get a couple percent better mileage - which could save you a few dollars a year - but my guess is that your entire savings is gone when you then also take into account the greater cost EPS to start with, and the greater cost when it dies and you have to replace it, and the much greater chances of it breaking: It's a very complex system involving wires, semiconductors, electromagnetics, and a computer chip more complex than the one that first landed on the moon: The average rate of failure and average yearly cost of EPS repairs per thousand cars FAR exceeds that for engine driven hydraulic power steering, and this cost severely consumes the slight fuel savings brought by EPS. Hydraulics last an extremely long time, are very simple, and nearly bulletproof.
This person trying to explain the mechanism and place so much effort, persons who click "Dislike" have either nothing better to do or no technical knowledge.
Agreed. The rotary valve was quite something to understand
Awesome video! Well done, No stupid filler BS. Right to the meat and potatoes. Super refreshing. Thank You.
That's my style!
Any idea, my car has usually a numb and heavier steering, then one day all of a sudden the steering got perfectly light and smooth for two days, before becoming numb and heavier again.. Changed the pump, the reservoir, correct fluid, steering coupler, ball joints, strut bearings, rack not leaking, pretty much everything checks fine. Not electrically assisted. Only the spool valve remains unchecked. Can the rotary valve do this?
Never heard of it, possible you have a clogged system?
This is what I'm thinking, I wonder if the valve itself can become clogged - the rest of the system appears to flow freely
I'd be interested to see what you find if you open the pinion valve, I've got a Volvo S80 with something similar, except the assistance comes & goes in a "twitchy" fashion depending how much pressure I put on the steering wheel. My thoughts were either dirt/sticking valve, wear in the joint of valve to pinion (the pin in this video) or possibly I thought the torsion bar could have fatigued after 194000 miles on mine but not sure.
@@danmackintosh6325 I am quite convinced now the system is clogged somewhere, perhaps at the rotary valve or at the line from the rack to the fluid reservoir. What is more, because of this restriction, the power steering pump is 'forcing' against the fluid, and this drains significant engine power. I am fully aware that this sounds strange but I come to think it's true. Of course, there is nobody else saying this anywhere on Internet. But here's what I did. This is entirely experimental and very unconventional. I lifted the front wheels off the ground, fire up the engine (transmission in P), then kicked at one of the front wheels with some force, both at 3 o'clock and at 9 o'clock. The reason for this I this will force the rotary valve to quickly open and shut, and perhaps this kind of 'kicks' into the debris that may be stuck in there, and may dislodge them a little. The result of this was very surprising. For one, once back on the road the steering felt like it was completely damaged: vibrations, kicks, shakes strongly. It never did that before. But then after some driving all this vanished and the steering become very light, but what is even more impressive is the engine power and sound, it felt just like the engine was back to it's young days again. My understanding is the strange steering 'kicks and shakes' were the result of something getting unstuck or unclogged. Unfortunately the light steering lasted only a few days. I'm repeating now this treatment. Again, after kicking the wheel the steering felt really scary, but that goes away within a day or two. I wish someone goes remove the rotary valves on these S60 and let us know how it looks inside.
Let me get this straight, your issue is on a Volvo too, an S60? That's interesting if so, seems a fairly common problem (still very uncommon mind, just more than on other makes). If I'm right, and yours came to you with red ATF/Dexron II instead of CHF for the fluid then it could be some reaction between the two types of fluid causing "clotting" in the valve.
Fantastic video, thx!
super interesting engineering involved.
btw is your brother looking for his toothbrush?? 😝
Thanks. He doesn't use his Toothbrush so I put it to good use
Hmmm...what kind of a rebuild is that... I'm not sure but it probably won't work once you put it back together..?
+mashed-\ /-out This isn't a rebuild video...
