- This legendary Toyota Tacoma 4x4 has some rough driveline vibrations.
The rear differential pinion bearings have quite a bit of play in them at 260k hard miles.

I've taken up the play like this with a rattle gun, on many landcruiser and hilux and never had any problems. Thanks for all your video 👍👍
Very subtle adjustment, well done. I never would have shown that air filter to anyone! lol Thanks Ivan!
When i was a kid about 50 years ago, fitted a new oil seal in diff pinion and didn't know anything about collapsible spacers and did the nut up with an air wrench, took the car up the road and it made heck of a noise, i overtightened it, car ended up with new differerencial...oh dear...Fred in England.
I did the EXACT same thing about 20 years ago. Learned a valuable (~$1000) lesson.
@@BlindBatG34 Yes i never done it again lol
If its over tightened will you hear hear a metal on metal chirping sound and random shuddering in the front end? 2008 jeep grand cherokee 166,000 miles
when you post a car related video, i get all excited like a kid watching cartoons on saturday mornings back in the 90'S.
I do the same thing when I come across a loose pinion. One of two results will happen: it will work great for years and years or it will loosen up again as the bearing wear out.
Thanks Ivan, the one I built was the none locker type but the process is almost identical other than the install and the removal of the locker actuator.
Keep going, keep going.... Ups snapped. Good job Ivan. Greetings from UK/PL
Nice short video... right to the point.
Plus I love hearing the Northern Flicker in the background.
Watching from Newman, Western Australia. 👍
MALS!
Andrew (ASPW) recently went through your town to Point Samson. I get to see your area/town. I just looked more about your town (Armstrong way) and I see there is a good community living! Greetings from West Texas
I'll bet his oil is a real Gem also. Probably have to chisel it out!!! Good customer!!
Nice little fix Ivan, every ounce of prevention = a pound of cure 👍
1980 Dodge Colt front wheel drive. Lots of miles, front wheel bearings had slop. Put a dial indicator on it and measured the slop. Divided the amount by 2, used the surface grinder at college to reduce the thickness of the spacer. Drove it a couple more years until the body started falling apart.
I was researching pinion bearing forces (axial loads vs radial loads) and came across your video. Kudos to you for doing such a nice job of taking up the play and maybe getting many more miles out of it. 260k is already pretty good. ZUK the gear guy 😎
He's got us beat by 1k miles over our '86 Grand Marquis! Nice!
Amazing with all that slop, the thing STILL didn't leak a drop! If that was a Ford or Chevy, you'd be rebuilding the rear after it fried itself to a cinder due to lack of lubrication, lol!
i have bean a mechanic 30 + years have done same adjustment 100's of times with no problems may not be the the proper way but seams to work with out having to spend a lot of money for nothing .keep up the good work
hey guys is the ratoation clunch normal tho ? fill me in please
Great Video Ivan! I did chuckle when you used an old American slang term describing play at the pinion.
Excessive play and " Slop ". Omg! Buddy that's old. Lol
That filter was rough, but I suppose it did the job. I've seen a few diesel trucks try to turn those filters inside out with less dirt than that. Thanks for the status update at the end.
Well this video cements it👍. My '03 tacoma 4x4, 130k miles will live longer than me !!!!!!!!
10 years on any filter..... why ?
I wouldn't count on the bearings not being worn out or even pitted.
When the Dana M80 diff bearings started whirring & the gears started to get a tad noisy I replaced the bearings & reset the diff lash all by myself, the small pinion bearing had damage done to the inner race & ithe pinion bearings had lost all of their preload.
As it goes with using unlapped & used gears you might get a bit of a whine like I did at 60 kilometres per hour (40 Miles per hour) but I don't worry about it.
The solution is to replace the gears as they were a little bit noisy to begin with !
very helpful video ! I have exact same problem with 93 pickup going to try and tighten it tomorrow
Smashing :-D, way less slop and next to nothing in parts :-D
How did the engine run at all with that filter blocked, the owner really needs to maintain it more often.
Sometimes you just have to peak and tweak until it looks and feels better.
I use a 50/50 mix of USG dry wall compound mixed with 20/50 castrol synthetic for these old rigs.
SAW DUST WORKS ALSO. FOR A WHILE. JUST ASK OLD CAR SALESMEN.
👍👍
keep on truckin
Very nice video. Great job taking up the slop! Be careful as the crush sleeve might be worse. Idk. At least it's maintained well. If you're happy, I'm happy! Hahaha! Great job!!
Yes Ivan the practical mechanic has an awesome channel. Another good one is the Hondamobilemechanic. Both excellent channels of course yours is included don’t know if I’ll ever work on a Genie Lol but they have the replace. Stay well Artie 😊 I wonder if thr ring and pinion gears are meshing correctly in the rear ended housing. I do know everything has to be shimmed correctly. Well I’m half way through the video so maybe there is bonus footage Lol
did the same with a wheel bearing of the same design got 20.000 miles more out of it
ivan im not sure its best to use an impact for this procedure what you think comrade ?
That original K and N never filtered better!!! It probably actually performed better clogged up, meaning it sucks when it's clean.
Didn't the adjustment on the diff mess up the backlash? Sounded like there was a lot when you rolled it back and forth.
It really depends on if the bearing are worn excessively. The back last adjustment on these is performed by turning the adjustors on the side bearings. That process is time consuming since the axles shafts and the differential pumpkin has to be removed from the axle housing. The back lash seemed like a bit much but cannot be measure by the pinion movement since when the pinion moves we have to take up all the slop in the rear end. Pinion to ring gear slop, spider gear slop and spider gear to axle shaft spline slop.
Nice hardworking Taco!
I think you did good that's how I did on my truck and probably put another hundred thousand miles on it since then and it's still doing good no noise oil looks good still, it was a loose like that not making noise or nothing not leaking I just took up the slack in it but mine did not have a crush sleeve in it it had the regular spacer I had to take it apart and I just ground a little bit off of it and tighten it back down and kept doing it till I got it right and reuse the same bearings and the reason I'm watching this right now is because on my BMW I was rebuilding the rear end and could not find one of those Crush sleeves anywhere so I tried to straighten out the old one a little bit and reuse it and I tightened it back down to where I thought was pretty close and I drove it and rechecked now I have metal in it well oil is dark color I don't know if it's just breaking in or what hopefully it's not too tight I do not want to chew the bearings up and I do not have one of those inch pound torque wrenches that they use to check them with so I just felt it by hand
Wow, they just send you a free filter if you never clean the old one? Sweet!
I would like to see a factory video of how the differentials are set up at the manufacturer, it is a time-consuming project doing a GM rear, wonder how they solve the setup issue at Dana, etc
Did that having slop in it cause the rear end to vibrate a bit? Or humm ? Good video
Maybe Im wrong but aren't you suppose to wash your K&N and re-oil every you know 3 years or so, Im lost here. That looked like it was never washed, Thats kinda the selling point, wash and reuse.
Yup..wash and wear
Wash, oil, repeat.
Yes but most people don't I think it's pointless unless you actually tune the ECU there hot air intakes and only good if you want more induction noise
Yup. Wash, let dry and then apply the smallest amount of oil possible to give the filter a hint of red tint. The only problem is most over oil them and then the mass air flow sensor gets an oil bath in the first 100 miles as the filter sheds the extra oil. Lean running codes and low power as a result.
Will doing this change the position of the pinion to the ring gear in any way?
I wonder how many of us Northerners are pulling up older footage? It's clearly not summer any more... lol
what size nut of the pinion bearing? thanks!
So when are we getting together to work on my truck?
Actually, the inner races moved towards one another when tightening the nut. Not a fan of using an impact to tighten the pinion nut, it wrecks the roller bearings.
Can you share some advice on a more precise option please?
Bolts in the flange and a bar to stop it from moving and a ratchet?
@@jasperwafflewool1957 There are specially made tools to do just that. Yes, hold the flange from moving and use a ratchet with a long handle. Check clearances frequently to prevent over tightening.
I have play on the front differential any ideas on that.
Man a Tacoma with a frame that's not rotten is worth all the money, better repair that thing.
watching in Ireland
Ok
My uncle 1996 mercury grand marquis gs is making a clunking sound when you put it in reverse and in drive. I thought it was the u joints but they're fine so the guy said it was the differential. The differential have play so can it be rebuild or he have to buy another differential?
Kendra & Natalie...Nice filter, although I'm not sure it's better than an OE filter
Worse filtration than paper filter. Watch Project Farm video.
Using an impact wrench to tighten bearings is hammering them . Not good for long life...but at 200k miles...
Almost 300k miles :) And the impact is only hammering the nut, not the bearings!
Meeeeehhh, it doesn't matter. If it breaks from an impact rattler it's gonna break from being used.
I believe the Pinion nut, crush washer, and pinion gear are all supported by bearings, and in service, rotate together. When the impact is hammering on the nut that energy is being transferred to the pinion, hammering it to the ring gear. The ring gear does not move but the high speed , point source impact at the one spot effects the ring and pinion introducing a wear spot. sorry for not being clear
Interesting to hear you say that, I've seen many professionals use an impact on the pinion. What I hear you saying is that an impact is OK with the ring gear out, when the tech holds the pinion stationary in his palm. I wonder how they do it in the factory. When the diff is already installed, there is no way to hold the pinion stationary with a hand. So there is extra stress on the ring gear/pinion interface. The pinion has some mass, and it doesn't seem to be so difficult to hold the pinion in a palm when taking up the slack with a short burp of the impact. Certainly it is easier than it would be to hold back a drive axle when a vehicle accelerates. Once the slack is taken up, energy goes into crushing the sleeve and resistance of the threads, and some of that resistance reduces the torque needed to hold the other end stationary. Like tightening a bolt, once it tightens down, the wrench at the other end often doesn't need to do a lot. So I would guess the strain on the ring gear teeth is small, but I don't know. The alternative is to use a long cheater bar, which would be really difficult without a lift....
I would expect even a truck (Toyota for that matter) to need pinion bearings if it has 260k on it. Especially if it's been used for towing or hauling. This isn't entirely out of the ordinary. I've seen much worse on vehicles with fewer miles.
I have this problem in my front differential how I can fix this??
Interesting that K&N sent a new filter. It looked like the owner NEVER washed and re-oiled it, which you Should do once a year or so. Just saying.
What can I do if my pinion it's worn out
Good Fix!....Was the differential fluid ever changed?
I changed it a few months prior to this repair at 257k miles when the diff actually rusted through and began seeping oil haha. Drain, weld, and refill :)
@@PineHollowAutoDiagnostics wow. I’m no Toyota fanboy, but that’s impressive. Great job in repairing these items using simple methods. In my world... we call that redemption.
but ive only done one in my time a 96 suby legacy i had the dreaded 17 blinks
Are they bad about rear wheel bearings too ? Mine is making noise, damn the bad luck
sweet fix Ivan... Eric O. has a good vid on a front diff rebuild also...
Yep. Check out his rear differential rebuild(s)

Karen and Nancy doesn't add HP but the sticker that adds at least 10 HP!!
Did you restake the pinion nut after tightening it?
Yeah. But it's not going anywhere lol
Chris fix, is it you??
that guy is like money in your bank account.
Sounds like Chris fix..
Well that sucks. If it is my vehicle I'd have to replace everything from the diff to the front main seal.
if the seal aint leaking leave it alone.
It had vibrations remember
Would not tighten that nut and would not use an impact either. That diff needs rebuild.
You should be measuring preload not "getting rid of slop"
Like #180
Thanks for the video!
Doesn't that nut have a torque spec?
The bearing play is the important part :)
No, actually you use a torque gauge on the pinion flange to watch the torque it takes to move the bearing, once you get to that number you stake the nut in place. That sets the bearing preload, if you go too loose the bearings will make noise and start destroying themselves, go too tight and they will generate a lot of heat and burn themselves up.
@@Blazer02LS not only that, the more you tighten the nut, the more receccessed the pinion gear becomes. It throws the alignment of the ring gear off as it is set by the pinion position.
I don't know if half a turn or more after this was set will make a big difference or not. But it will change how the gears contact each other and increase backslash.
@@sumduma55 It shouldn't do much in this case as it's been loose a while so the damage is done. As long as it stays quiet and doesn't get hot it should be OK.
Deez nuts? You tighten the pinion nut until you reach the proper rotational torque for the bearings. Since the bearings are worn, zero lash and zero rotational torque should be fine. Can’t be worse than all the slop ( lash ) that it had.
Loose pinion bearings on Toyota lift truck..yikes😵🤣🎄👍😀🤔
Filthy K&N filter. Poor maintenance. Clean it every 15,000 miles. It only takes 30-40 minutes if you dry the filter on a fan.
Guy dosnt know what he’s doing there’s a crush spacer if it’s sloppy it neeeds bearings yeahs going to far changing the backlash
front seal bad and front pinion bearing pitted and galled, maybe the rear also from water/salt ingress they'll often still feel pretty smooth and turn ok, but once taken apart, ugly ugly.
Getting famous off comments day 191, so I can live the dream, live everyday like it’s your last day🚀🤙🚀
Or get a job

I want to hear the problem sound, not your voice.
Pine Hollow Auto Diagnostics
If you have play in the pinion bearings, they are already shot. You don't just lose pinion preload unless the bearings are damaged. Even if the nut backed off, you need new bearings and a new collapsible spacer. Where is your beam torque wrench to measure pinion turning preload? This is a hack video, please show people how to do it the right way instead of damaging their vehicles further. Having a customer drive 15K miles on damaged pinion bearings is nothing to brag about.
One very important question is do you know JESUS CHRIST AS YOUR PERSONAL LORD AND SAVIOR?
