Rear Diff Problems

[JoFotoz]

Without hearing the the noise...

...or seeing the wear on the u/joint its hard to know.

BUT....$850-$900 seems expensive.

You should be able to source a good used rear 3rd member for $250 ish..
....and fitting it shouldnt take a good mechanic more than 1.5/2 hrs.

I thought it seemed pretty spendy too. There is no "noise" other than a pretty bad vibration starting around 20mph. No whine. I rolled around without the rear driveshaft around the block and the vibes went away.

I replaced the "front" ujoint but not the rear because it "seemed" fine. After taking it back out I noticed it seizes up a little bit, not as smooth as it should be. The shop told me that replacing that ujoint would be a band aid fix as it would wear down quick due to the bearings.

I've assisted with a lower gear swap in an old toyota, and feel pretty comfortable with doing the work except for the fine tuning of the gears.

Gotta love a DD project... ha..

Just FYI, $800-1000 is pretty standard on NEW axle parts, done correctly with fresh seals and bearings.

Ive done a lot of research when mine went, and thats going rate. $150 for the ring and pinion, $150 for the master seal and bearing kit, the rest is labor.
And yes, it sucks to do the front, the rear isnt as bad, but the front is a *^&#...

I ordered mine from 2 different companies, Had the rear done by a shop because i needed it on the road, they charged me $850 out the door, the second time, when i got to the front, i picked up a new third with new gears, seals and bearings for $800, and did the install myself and saved about $400.

I have found that the 12 bolt pinion can loosen up over time. It uses a crush sleeve to set pinion preload, and I think it just crushes a little bit over time. Some times you can tighten the pinion nut back down a little which keeps the pinion from moving around so much. It won't fix the increased backlash, but it does help with the vibration. The 12 bolt is so strong that if you really wanted to fix it I have no doubt that is you installed a new crush sleeve and reset the backlash and pattern it would be like new. The bearings and R/P are big and durable, unless completely abused you can probably reuse them.
