2001 Grand has "thump" in rear end
 

My 2001 Grand Cherokee developed a "thumping" sound in the rear area at low
speed on bumpy roads. Started around 40,000 mi...now at 60,000 mi. Getting
worse. At first I thought it was bad shocks and replaced them to no avail
at 45,000 mi. I have looked at everything I can think of that might be a
problem and cannot find any reason for the noise. Spare tire is tight, no
loose items in spare tire well, suspension looks OK (no visual evidence of
anything moving around), brake pads are secure, exaust is tight, ujoints OK,
sway bar is tight, etc.
I am begining to think that something in the rear suspension is loose or
sloppy enough to allow a small amount of movement and cause a thumping sound
as it moves around at slow speed. However, I cannot see any evidence of
that. I have rebuilt Jeeps from the ground up and generally I can track
down problems but this has me baffled.
Has anyone had any problems with the rubber inserts in the rear suspension
that might allow some slop in the joints? I suspect that is where the
problem is but I don't want to tear it apart unless I have to.
