$750 to fix the rear differential noise?
Hi, folks,
After resolving the electric problem with me recently purchase 99 I6 AWD auto cherokee, I sent it to the garage to fix the infamous rear end noise.
The garage said the bearing in the differential is gone and the cost to repair it is around $750. The owner of the garage is against the idea of swapping in a used rear end since he (1) is uncertain of the quality of the used parts (2) the stock rear end on Jeep tends to go wrong.
My question is, (1) is $750 a reasonable charge? (2) Is there any other more economical alternative?
Thanks.

Well, they don't know if other parts need replacement until tearing the differential apart. So you think they charge too much for rebuilding the rear differential? Thanks.

Well this is why i think it's too much. My friend took his rear axle in for complete gear swap and overhaul (complete rebuild including new gears and pinion) for about the same price. This was to a professional gear installer too. You were quoted $700 just for the bearing replacement and who knows what else could be bad (probably nothing though). If it's your only option then you may have to do it. It is possible to do it yourself but a little learnin is required on what to do and how to do it properly. It's not just a "pop out old, pop in new, tighten" procedure.

Rear ends aren't hard to swap just need some jack stands and a big jack. Jack up and sit on stands. Pull tires and crawl under there and unhook up brake lines, drive shaft and electrical conections. Take a jack and put pressure on the rear. If you have an impact to use to take the the U-bolts out use it. Drop the u-bolts and ease off on the jack and pull the old rear out and replace with new. Then revese the process to put in.
It helps to have a few people to help with lining up the new rear. I may have left out something but it is real simple if you have basic mech. tools you can do it. It takes us about two days to do a big F250 in a gravel drive way, but you can do a rear in about a day. The hardest part I think is the U-bolts, Getting them off with just a 15" breaker bar and a pipe.

Finney left off the e-brake but that is pretty much it. Use another Cryco 8.25 and check the gearing and you will be good to go.

Usual prices for a rear axle.
$200-250 for labor
$100-125 for master rebuild kit
IF putting in new gears $150-225
Seals if not in the kit $10
Estimate $610 So $750 isn't completely out there.
Junk yard axle $150...Take your time and swap over your brakes to JY axle...if you do the labor yourself...Your our 150 plus fluid $16 and a tube of rtv $5 or $171 total.
Axle swap isn't bad if you have air tools...U-bolts are a bit rough without them.

All the bearing go south
They garage torn the diff apart today and found out all the bearings are bad. Is it a common problem for Jeep differential? Will it be OK to leave them unfixed? The labor charge for this repair is really high.
