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????
