Rear bearings 98 GC 5.9
 

Would it be unusual or indicate an inherent problem for the bearings in my
rear differential to be shot at 56,000 miles......no towing or off roading?

Looking for opinions from Jeep experts....I am not one!

Thanks

Hi BEK,
Yours is the only car I know of that may not be jacked up using
only one floor jack at the differential housing. That's how yours was
bent, and I don't know any recourse you have, other than to shell out
four thousand dollars.

OK, *I* will say it then. What Bill said is most likely true. Differential
bearings normally last the life of a vehicle, except if it is raced, taken
off road, subjected to heavy duty use, etc. or has one of those cheap-ass
aluminum differential housings like you have. If this vehicle is otherwise
in good shape and worth keeping, you might want to investigate getting a
"real" cast iron differential housing for it.

Those seem to have a problem with bearings. I see it posted often,
usually at lower miles than yours has.

There is a TSB out on it, here is part of it:

Thanks to all for the info. Now I'm beginning to get the drift....Chrysler
puts a cheap-ass aluminum differential housing on to save themselves a few
bucks. Then, the first time the unsuspecting owner has his Jeep jacked up
for new tires or whatever, the housing is bent. This causes premature wear
on the bearings that are supposed to last, perhaps, the lifetime of the
vehicle. Just priceless! And at least one thing is for sure.....I'll never
buy another vehicle from them as long as I live.

This axle got even worst in '999 on the WJ. Dana has caught Hell for it and
is probably going to lose their DC contracts. Issue there was R&P setup. My
'01 howls like banshee when cold and coasting downhill. Dealer said it was
"normal". (It's got a 70k mile warranty that will prove them wrong.)

You can't blame Dana for the failure, it's Chrysler that assemble
the "C" clip rear ends.

FWIW, I just had the "Jeep thing" transmission/Xfer case leaking problem
fixed('97 ZJ 55K) at an independent transmission / axle shop that does a
lot of work on Jeeps and I had an interesting discussion with the guy
about ZJ rear axles. He said the iron ones are going bad too - just not
quite as soon as the aluminum version. He also said the axle is
virtually identical to some Danas GM uses and those don't have problems.

He did mention the service update which recommends changing fluid every
25K and said the ones they've been doing that way seem to be OK, but why
he wasn't sure - after the first change the old fluid comes out looking
just fine. He also said something about the Moly-B additives used in
gear lubes bonding to the metal parts when the lube is fresh????
