Vehicle Shudders when accelerating - found multiple problems

[@theoriginalchefboyoboy6025]

I just noticed the shuddering on my 2016 Taco a few days ago. Seems to happen around 25 MPH and 1500 RPM, low gears, 90k miles. Very grateful for your thorough examination. Cheers, mate!

[@mannycarlos5088]

Mine is doing it too. Did the video say he actually fixed it? Didn’t catch that part

[@aoekone]

I’m having the same problem. The carrier bearing was not the problem. It’s been going on for one week now . Back to the shop I go to trouble shoot more in depth. I think this might be my problem

[@CAgenius]

@@aoekoneany solution for ya?

[@aoekone]

@@CAgenius it’s the torque converter . Fixed it with a transmission flush and added the shutter fix additive from autozone . 20$ . No more shutter. Torque converters are a problem with the 3rd gen tacomas

Excellent presentation, sir! Thank you. My Taco has the same shudder issue. This might just be the problem here.

[@mikeparker9692]

These videos show your integrity so much that it makes me want to buy a Toyota and move back to California! Great job!

[@mrvang8077]

I'd stay wherever you are at. Not worth coming to California. The cost of living in california is ridiculously expensive.

Hopefully we'll get to see the full repair, great presentation Peter, very informative, as always 👍👌

[@johnmgrondorf6489]

I had the same thing in my truck, coils were bad fixed there are 3 in moter cost $1000

[@eh2341]

Because my Taco is a '17 this video made me nervous. That is, until the very end when you talked about how well the truck held up. 180k miles is alot. Mine has 50k and I don't drive her much since I retired. Still, she's my baby. I'll subscribe. Thank you

[@JLUjeff]

Great job! Thanks for walking us through your thought process to narrow down the problem. Really helpful

[@TylerDickey1]

This channel shows great proof that milage is not the best indicator of vehicle condition. Show me the maintenance records! This truck is in better shape than others I've seen with half the mileage.

[@LAactor]

But also consider this likely is a highway life truck. A city truck gets beat to hell on the pothole roads and accidents from parking lots and city traffic and bumper to bumper errand use.

[@edroams2404]

Thank you for being so detailed. Great video.

[@stevanrose7439]

Peter you always have a very informative video on the Tacoma trucks. I have a 2012 and a 2002 and you cover a lot of things with your videos. Once again thank you. And looking forward for your next one.

[@josequintana6526]

Peter sounds like you were fighting a cold. I enjoy your videos. You have a detailed presentation and an experience of logically diagnosing malfunctions on a vehicle. Very different from those who replace components and if you bring it back to them, they give you the line that the component needed replaced anyway. Those moments are particularly frustrating to me. Keep up the great work and may you have greater success in your business in the coming year.

[@dalephillips8250]

thanks for showing us your troubleshooting path to finding the answer.

[@TheOfficerBell]

I had all kinds of shudder issues with my 20 Tacoma within 20,000kms of owning. Toyota couldn’t figure it out. Techs agreed there was an issue but eventually changed their tune to it being “characteristic of the truck”. Got rid of it as soon as the used truck market exploded.

[@Enchanted3DPrints]

none with mine so far. 26k miles

[@williamehman6007]

Same here... I'm gonna have to fix it myself...

[@steveyountz9184]

Another great effort on your part.

[@Gilibob13]

I’ve had shaking when accelerating in my 2005 tundra V8. It took time and $$$ wasted changing parts that didn’t need changing to find source of the shutter. Turned out in the end was from the rear differential. Nothing was wrong with it but some idiot changed the dif oil with incorrect oil. The truck is a 2wheel drive TRD and has a limited slip. Regular dif oil won’t work, it needs to be LSD oil and there’s a sticker there stating that.

[@dalephillips8250]

Thanks for the info.

[@joedominick7517]

Peter, I’m new to your channel. I appreciate the details of your videos. Keep up the good work.

[@markpelenytschka8374]

You are a Master of Deduction

[@stuartstuart866]

I might consider putting oil, even used oil, in the differential to see if the shuddering goes away. If it does, maybe the gears aren’t ruined from lack of lubrication. At least you’ll have a clearer picture of what’s going on.

[@LAactor]

I think just a bearing and axle seal replacement with rear diff service is MUCH better than needing a new trans.

[@jaygold4467]

Come 180,000 miles you're going to spend 2- $3000 in maintenance. Things start wearing out. That's just the way it is. If you want to keep the car you're going to have to invest in it. Things don't last forever.

[@LAactor]

But Toyotas definitely last longer and closer to forever than many of it's competitors from other continents.

[@kendallwright7222]

got over 320,000 miles on my 2015 Tacoma and still going strong. Learning to do as much of your own maintenance and repairs as possible definitely helps keep maint. $ down.

[@revilsdr]

For that amount of miles the truck is an excellent shape especially the underbody he’s obviously taking decent care of it. With that amount of miles parts eventually wear out need replaced, fluids flushed and replaced.

[@awakeandalive4248]

@@revilsdr. My 2008 Toyota corolla has 165 thousand miles and has zero leaks zero problems and all I do is keep up with all preventive maintenance, I don't see this car giving me any problems until it gets over 300 thousand miles maybe 400 thousand miles.

Can you verify the size of the bolts used to push the drum off?

[@NebuChadNezzarKBDN]

Great information. Thanks.

[@ThatManitobaGuy]

That sucking noise when the rear diff fill plug was removed indicates that the diff vent is seized/plugged and likely caused the axle seal to fail causing the low rear diff oil.

[@LAactor]

Goos point! If that vent is clogged the pressure from the super heated oil can blow out the seals.

[@LAactor]

@@Neodymium5312 you said not make any suck noise? Then it's good according to the above commenter. You should check the vent cap. Reach in and spin it. If it's hard, it's blocked and take pliers and spin it. If you break it off who cares. It's like $10 to charge with a small deep socket. But easier if you don't break it. Just spin it.

[@rxcalvosa]

Wouldn't both sides be leaking?

[@janpur1417]

Soon after I got my 21 Taco (just 20 miles) I checked all fluids: Heard a hissing sound (suction) when I loosen the rear diff and manual gear box filler bolts. I am glad I check all around. Found a unreleased heater hose clamp at the Pass-side firewall! You must ensure the rear axle oil seal rides right in the middle of the ABS ring retainer. Otherwise, it will leak again. Check Timmy the tool man's 3rd gen 4runner axle repair (sharpie test). My 97 4R at 220K miles and original front bearings, 92 coroll at 283K miles and all original bearings all around. TAco's should be tough but can't believe front bearing is already shot.

[@williamtukeyjr3661]

Peter is the best!

[@cjpamp1267]

It would be nice to see repairs being done on the vehicles again. Nothing is better then a visual repair to see what the person is up against

[@j.james.s.2412]

I've a 2010 tacoma trd 4.0 and am 270 miles from 255,000. I recently noticed this odd shudder occuring between 30-40mph when accelerating. Its been slowly but steadily becoming more apparent. Trying to discern the cause without spending $10,000 at a mechanic. Im not equipped to do many of these repairs myself.

[@efil4kizum]

why so much? 10k! is that what you were quoted?

[@j.james.s.2412]

@efil4kizum No, no. An exaggeration I assure you. I am however very tight in the budget so if I could fix it for the cost of parts and time, I'd take that. Likely I'll sell it in the next couple of weeks though

[@victorshaw7173]

I noticed my axle U-bolts were under torqued after 80k miles when I decided to check.

[@davecalvo6418]

great video Peter, I would have liked to see if the vent on the rear dif was clogged?

[@bash7102]

Yeah really. I would have replaced it for sure as part of this service. I thought I would have to replace my axle seals but replaced my vent valve first and no more leak.

[@LAactor]

Some VERY good points 👍 in this video. I don't know why that location bearing always wears out first. My guess is an extra 200lbs of man meat being thrown around directly over that area in the cab has something to do with it.

[@plutosforest]

I am surprised the bearing is failing at all, I've not experienced that issue with older Toyotas.

[@LAactor]

@@plutosforest my guess is road conditions along with driving style. I did a long write-up on a comment about this months ago somewhere on another video on their channel. Some drive their trucks hard. Some roads abuse the parts of the car more. Maybe even some drivers turn the wheel harder or drive and turn more. Who knows. All we know is it's always that one if it happens. At the dealer when cars come in, it's that one.

[@KW-vy7xl]

You should check the rear differential breather. If it goes bad, or gets dirty, and fails to vent. The gear oil will vent out the axle seal.

[@blackmamba474]

I relocated my diff breather near the gas filler

[@BrianSmith-si4zd]

12 year toyota tech . Definitely a plugged breather you could hear the pressure release when he removed the fill plug.

[@SpicyMcGeezaks]

@@BrianSmith-si4zdhow can you tell if it’s plugged up?

[@ztemde978]

Thank you sir a great example of troubleshooting and critically thinking to resolve an issue. I would assume the owner didn’t change the fluid which wore out the seal? However, parts do go bad and don’t last forever.

[@captinbeyond]

I was wondering the same thing and also wondered why it wasn't brought up in the diagnosing of the problems

[@jeffreysantos9070]

Great detail presentation! But I recommend Not to perform a transmission flush. I did that once and my transmission shifted troublesome. I now perform drain and fill transmission fluid.

[@LAactor]

Something may have been jammed backwards where it wasn't supposed to go as well. The passages look like an any farm maze if you ever seen one open before.

[@parisachilles2682]

A tranny flush in a high miler is just borrowing trouble. Better to drain and refill than taking the chance on a flush.

[@michael184272]

Is the so called "Drain and Flush" just the amount draining from the pan once every so often, or do you drain and flush, start the vehicle and repeat several times until you get clearer fluid then what came out on the first drain..?

[@bash7102]

I drain and fill trans pan with every oil change and use only Toyota ATF WS.

[@im_caiman4479]

With that many miles, it will do good to also grease the slip yoke on the propeller shaft. Greasing mine stopped the shutter.

[@michael184272]

What type grease is recommended on the slip yoke and is it different then what's used for the universals? Thanks in advance

[@im_caiman4479]

@@michael184272 I recommend Ford Motocraft PTFE lubricant. The blue stuff. I heard about it on a Tacoma forum. Comes in a small tube. Make sure to clean off the old grease. Also, if you have a second gen with LSD, make sure you have sufficient limited slip diff additive in the rear diff. This can help solve shutter issues as well. Just my 2 cents.

[@cococlayton1]

Did this fix the issue? My 2016 Tacoma does the same thing, but my brakes and rear differential are fine. I’m interested to know if this solved the problem.

[@cpsmonroe1]

At 135k , dealer said my vibes were from my AT tires ‘wearing’ lol. New front bearings had 5k miles. I found I had 2 bad u joints so I replaced them all. No more shudder and vibe.

Great job, my 2007 TRD OR tacoma did same thing. Big price tag!

[@uhdahnbracquemont6746]

I am having the same issue, 2019 Tacoma with 68000 miles. when it's cold it does not shudder only when it gets to normal temp after driving 15 min then it starts at acceleration at 20 then stops then again at 25, 30, 35, 40 then it stops at high mph. checked and cleaned mass airflow sensor. The dealer did install a new fuel pump just recently due to recall and when i got it back 2 days later it started to shudder. Maybe a drain and fill on the trans may help it? any advice on what to diagnose? also the dealer said that it needs a new torque converter, same dealer that installed the fuel pump.

Isn't it quite likely that there is some damage in the rear diff since it was running low on oil?

[@dadgarage7966]

Have you uploaded something specifically on 2003 and newer 4Runner/FJ Cruiser/GX470 (aka Prado) rear parking brake service problems? My 70,000 km 2009 4Runner has a strange problem -- with two nuts holding each rear rotor firm to the flange, the left side rear rotor will only rotate by hand in reverse while the passenger's side will only rotate forward with the truck in park, of course (open differential). It won't budge in the direction even with a prybar. The brake shoes and hardware are all original except for brand new O.E. Toyota shoe hold-down pins and springs and retainers. Even the the rotors, pads and shims are O.E. Toyota parts from the dealer with about 10,000 kms on them. The shoe adjusters are well-greased an backed off all the way in and the rotors slide on and off with ease. Everything has high-temp copper grease and the shoes and calipers move around freely. It seems to be only the right side that's acting up. I'm tired of pulling everything apart again to check. A Prado forum thread says that surface rust build up can cause this condition but I don't wanna just put the wheels back on and break something. Any insight? I know the shoes are backed all the way off because the parking brake pedal drops all the way to the floor. I hate rotor-in-hat parking brakes. A service headache in rusty climates. Thank heavens the Tacoma still has drums with automatic slack adjusters.

[@LAactor]

I did have a suspicion in the beginning that you led me to the trans and you should crack the bolt to check the color of it anyway but my real suspicion was the driveshaft and then diff. But you proved it wasn't one and I am almost certain that diff is dry! They already neglect that rest l rear end! Hopefully that fixes his problem. Aisin makes the trans and they are strong ones that just don't break. This truck may very well end up being one of those million miles tundras. Something like a thousand miles a week is a lot!

I’m assuming his rear differential oil is really dirty and has never been changed which would have contributed to the leak and problem.

[@Prosecute-fauci]

I have a 2020 Tacoma TRD Off-road and the dealership had to replace my rear differential at 6000 miles because it was howling. When the guy drained my Diff he kept a sample and it was black as pitch. That rear diff should have been making some kind of noise as it was running down on oil.
