Well here we go... Last week i heard a squeaking sound (like a bad bushing) when i would back up under low speeds. It would only make the noise in reverse. After some research i thought that it might be a bad ujoint in the drive shaft. On m way to purchase one, i encountered a bad vibration at low speeds from the rear. I further thought that it was a bad joint. So, when i pulled them the joints seemed fine but the pinion had some play in it. At this point it was out of my league...

I have been told that it is more than likely my pinion bearing in the diff. The dealership quoted 700 to do the job.

What are your thoughts... How hard is this job for me to tackle (limited knowledge). Does the third drop out like the old 88 runners?

05 4door Tacoma, TRD, 2wd, 6cyl. Thanks

That sucks dude. Fuzzy bought an 08 tacoma and had the same issue, started as a gear whine and got worse. His was under warranty. I'm sure Jimmy will see this soon and respond with some insider info for you.

If you are out of warranty, Chase will fix it MUCH cheaper.

Definately call Chase. He can probably put a new third in the mail to you and you can ship the old one to him to fix and put back in stock. Chase usually has a pretty good supply of parts both new and used. This way you wont have any down time.

Order third and when it gets to your house, drop yours and install the new one. Ship old third back to Chase in the box the new one came in.

well, i have some good news (so i think). I took the taco to a local mechanic who rebuild rear ends. He checked the ujoints and the pinion shaft and said that everything appeared to be fine. He did not see anything to be worried about.

He took it for a test drive and noticed the shuttering, shaking at low speeds but could not dingoes the problem. His best guess was the tires.

Do you guys have any ideas.

this may be a stupid question, but how would i know if my rear diff failed? Is there any way to be sure that my rear is good without tearing it apart.

You could pull the drain plug and see what comes out. Some metal is going to be normal as you know, but it shouldnt be too much. I would be suprised to see it be the diff though....

So it only vibrates at low speed?

Does it always happen at one certain speed?

Does it do it when you are accelerating?

Any noises to go with the vibrations?

Does it do when you are decelerating?

Do the vibes go away when you are coasting?

Any noises to go with the vibrations? no noises

Does it do when you are decelerating? yes.. only at the same speed.

Do the vibes go away when you are coasting? yes on

after a week at the dealership they diagnosed the problem as a defected motor mount. I am not a car mechanic by no means but even i was a bit weary of their diagnosis. When i arrived to pick up my truck the tech was there to answer any questions (i liked that, very good customer service). I asked him how he knew the mount was bad. He responded that he punched it into the computer and it told him that the motor mount was the issue. He never inspected the old one and would not allow me to see it. They assured me the problem was gone.

Well, before i got out of the parking lot the problem was still their. I spoke with the head tech and they took it for a few more days. After still no solutions i called and asked if they would double/triple check the u joints. Come to find out that the front joint was binding and was replaced.

Problem solved. AWESOME!
