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.

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.

Re: '04 Grand Cherokee Lurch on Stop...
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.
