OFFICIAL 2nd gen 4x4 front differential bearing vibration thread

^ This

 

Thanks

 

Ordered the 1st gen bearing from ECGS. What did you guys use to install the new bearing into the diff? I don't have a race driver set.

 

Autozone will loan you a driver , you get your deposit back when you return the tool.

 

i picked one up from hf for like $30
worked great
but you can just use a socket or something too

 

this one

 

Thanks. I didn't know autozone had racer drivers as one of their rentals. Going there tomorrow.

 

yes ,I rented one from them ,60 bucks but you get it back when you return the set.

 

Problem fixed ,
I used a GoPro camera strapped to different locations and went for a drive.
The case on the camera was the waterproof sealed case , the case worked well by blocking wind noise to the microphone and the vibration would still get transmitted through the case .I attached it using zip ties to the rear axle housing near the diff and then to each front wheel steering knuckle on the bar from the top ball joint. I then listened to the recording and when listening to the passenger side front knuckle I could hear the noise . I checked the wheel bearing before and it was smooth and did not have any play . I changed out the wheel bearing /hub with the one I changed recently on the drivers side and hum/vibration gone. I changed a lot of parts before changing this one ...Oh well I am happy that problem is gone.

 

^^^ Hey tr1957, wow, good job. I like you already.

So it was the old familiar Tacoma front wheel bearing problem huh?

Will you please recap for us your mileage and if you are running stock or modded wheels?

 

1 3/8"

 

26k miles ,stock everything. I purchased this truck with front end damage and had it repaired by my brother who owns a body shop.The truck was hit mostly on the driver side front end which is why I thought the problem was on the the drivers side. My brother said it sounded like a wheel bearing which was damaged due to the wreck .after reading the info here about needle bearings/bushings and such I kinda got off track as to the problem.Hopefully the front diff bushing was preventative maintenance.The drive shaft also through me off because it had a dent and wobbled .The drive shaft shop said toyota does not machine the drive shaft and yoke and just balances it with weights.

 

^^^ Well, now you are vested in it and are going to have to keep it for a long time. Don't feel to bad about having done those other things. The front diff. is a POS and you would likely be in there doing the bushing before long anyway. Looking at your parts replacement list I don't see any unnecessary fixes given its history IMHO. And think of the attention you have given it.

 

***I have a 1st Gen*** ECGS now has the bearing for the 1st gens too. I purchased and installed it this past weekend. No more vibration. Thanks ECGS.

 

Hi all, I traded my 95 Taco with 290K Mi, running great for an 08 4 Dr. to have room for my rapidly growing grand kid. I bought the 08 last year with about 80K Mi. on it all was well until about 88 K Mi. now I have the "growl" . Toyota dealer I.D. ed the problem as drive shaft and estimated $1,500 to replace it. I replaced the center carrier and "U" joint myself with no improvement, all joints really appear and feel good and are well lubed.
After reading this forum I am convinced that there is a basic design/fabrication fault and that Toyota must know about it? Does any one here know ???

Thanks, bob

 

Ok, now on to the next problem... I hear a rattling noise like a chain sound for lack of a better description when I let up on the gas at around 55 mph. coming from the drive shaft or rear diff or maybe the transfer case sometimes. I noticed it with the rear off the ground and running the back wheels but thought it may have been due to no load on the wheels . Anybody know what this might be?

 

Exhaust shield?

 

There is a current thread going here on TW about possible transfer case chain rattles and vibrations. There is also one on Toyota Nation that dates back a couple of years about the same. The issue surrounds whether or not the transfer case chain actually turns, albeit slowly, when in 2WD. Might want to take a look these.

 

Thanks, I will check it out , I don't think it is the exhaust shield but will check this weekend.

 

discovered another issue ,won't go into 4 wheel lo.
The light flashes and beeps but nothing happens.
any ideas?
