I have had 4 Cherokees (85, 87, 88 & 91) and 1 Grand Cherokee (95) all well
over
100K miles and never had a diff bearing problem. The 91 Cherokee has 180K
miles
and still runs great. These all had Dana 30 &35 axles though. Have changed
the diff
gear lube every 30K miles too.

My brother-in-laws's was never used for towing or has ever been
off-road. I doubt the oil was ever changed in the rear, but *most*
people never change the diff. oil and still don't experience rear end
bearing problems.

So if I never change my engine oil or xmsn fluid or coolant I should not
experience

engine or xmsn problems either. Most conscientious owners change the
lubricants

per the maintenance schedule or close to it. If you don't...don't blame the

manufacturer for poor quality. I have had 5 Jeeps all well over 100K
without

a single differential problem.

That was definitly caused by lubricant breakdown & reusltant metal
contamination. My hunch is it the vehicle was overloaded or got overstressed
towing something beyong its capacity. The giveaway is the scoring on the
outer axle bearings & the axle shafts.

FWIW, the Grand Cherokee factory maintenance schedule calls for 12k mile
differential fluid changes if it's used for towing & heavy loads (i.e.,
severe duty). It also calls for an 80w-140 lubricant in the rear axle in
those cases.

That thing had to be growlng like a pack of mad dogs for a long time, too.
Would have paid to look into it earlier.
