'04 Grand Cherokee Lurch on Stop...

Unfortunately there aren't any grease zerks on the driveshaft, so it
was more of a "smear" rather than a "shoot"...

Bill, but I don't see your posts unless someone replies with your
content pasted as done above, partially. Sorry, but that's the way it's
gotta be.

Then repack them with normal lubrication, every six months, and that
includes other places where Real Jeeps have zerks like you door hinges.

I'm rather hoping I don't have to remove the rear drive shaft every
six months...

Only if you take it off road, or pull a trailer.

That shaft should be a one time lube, or unless you take it off again
for another reason. I was just wondering if you used wheel bearing
grease or general lube grease. General lube would make sense since it's
not a high friction area like a wheel bearing.

My XJ has experienced the same clunky movement on starts and stops
occasionally. I was thinking it might have something to do with the
block lift on the leafs since I've never used them before, but I may be
pulling my DS soon for a shaft lube.

It was a fairly easy job. Mine was held in by 4 bolts at the rear
differential.

Yup, I just would not have considered lubing the shaft to be the fix to
this movement, but I'd be happy for this to be the fix. Thanks for the
report.

As a follow up to a follow up, I tried this procedure and my 'bump' in
the XJ drive train went away. Smooth starts and stops now. Cheap fix,
too. Thanks everyone.
