I just bought a 2002 Wrangler 4L 5sp with 7K miles. It has never been driven off road, however, there seems to be some play in the driveline as there is a clunking sound when I tap on the gas at slow speed. I checked the U joints and they seem to be fine. Any sugestions?

Thanks,

DRIVELINE SNAP
A snap or clunk noise when the vehicle is shifted
into gear (or the clutch engaged), can be caused by:
² High engine idle speed.
² Loose engine/transmission/transfer case mounts.
² Worn U–joints.
² Loose spring mounts.
² Loose pinion gear nut and yoke.
² Excessive ring gear backlash.
² Excessive side gear/case clearance.
The source of a snap or a clunk noise can be determined
with the assistance of a helper. Raise the vehicle
on a hoist with the wheels free to rotate. Instruct
the helper to shift the transmission into gear. Listen
for the noise, a mechanics stethoscope is helpful in
isolating the source of a noise.  

I would quess transmission/transfer case mount  

ya need to check the joints with the tranny in neutral and E the brake on.
otherwise it'll be in a bind and you won't find the slop..

rear diffs that have a detroit locker have alot of play and can make clunks.
