WJ Issues
 

Well, a friend just recently sold his 03 WJ with 48K on it. He got real
disgusted with some all of a sudden issues. Both rear axle seals went while
he was on vacation. New seals and breaks no cost under warranty. Then his
front seals on both axle went some more head aches. Does any one know what
would cause this of course bad seals and not changing the differential oil
are a couple but is this an issue with WJs? One good thing that came out of
it is that he gave me 7 oil filters and 2 air filters free.

Just Curious

No idea unless a suspension lift had been improperly installed on it.
My wife has had two WJ Grand Cherokees with this one being a 2003 too
and both have been really good with no problems.

Re: WJ Issues
 

From all the posts about failed rear ends in vehicles made in the last 5
or 6 years or so by DC they obviously have done something wrong with the
design.

Not changing the oil in 48K is 'not' a reason for a failed rear end.

You don't hear of CJ or YJ or Cherokee rear end failures, but grands,
well... And a bunch of TJ's too????

#1 cause of failure in the ZJ is having some nimrod jack the rear up
under the diff. I see it all the time at a local tire shop.

It's not a dumb question, it's a dumb design. :)

DC used thin wall tubes and only pressed them into the pumpkin with
half assed plug welds to keep the tube from rotating. Jacking from
the diff can bend the axle assembly taking the bearings and seals out
of alignment just enough to cause excessive wear. Older thick wall
steel (welded) axles didn't have that weakness.

For the most part they all are. Car makers have cut weight where
they can and that has created weaknesses in what used to be your basic
hunk of iron. Now diffs are aluminum and the tubes are thinner.

It's just not a good idea to ever jack from the pumpkin. They make
trusses to strengthen axles for larger tires and off road bumps.
Some bolt, some weld.

Re: WJ Issues
 

Well it does make sense I had talked to my friend and he said he jacked his
WJ by the pumpkin all the time. I told him about the replays on the
newsgroup. He was kinda pissed that he may have caused the damage. I guess
that is why jacking points are specified in the O&M. I was wondering if
damage can be done by jacking the tube near the wheel? The TJ shows the
jacking points to be on the tubes.

If I have to jack on the tubes it's usually directly under the shock mounts,
or as close as I can get, so as to put the most force directly up and on the
suspension.

Got to agree it was hard for me not to jack from the diff. Did it all the time
in my old chevy. It was a dealership mechanic that warned me of jacking under
the diff when I was in there for some warranty work.

My solution was to get a 3ton floor lift. Just using the frame points it can
bring the wheels a good 6" off the ground.

The only time I have jacked under the diff was to raise/lower the axle for
some suspension work. And then it was just the axles weight. The ZJ was up
on jack stands.

If I have to jack on the tubes it's usually directly under the shock mounts,
or as close as I can get, so as to put the most force directly up and on the
suspension.

Got to agree it was hard for me not to jack from the diff. Did it all the time
in my old chevy. It was a dealership mechanic that warned me of jacking under
the diff when I was in there for some warranty work.

My solution was to get a 3ton floor lift. Just using the frame points it can
bring the wheels a good 6" off the ground.

The only time I have jacked under the diff was to raise/lower the axle for
some suspension work. And then it was just the axles weight. The ZJ was up
on jack stands.
