Could be one of the bushings in your control arms. Put the jeep on a flat
surface in 4lo and first gear. With the engine off lay under the vehicle
and have a friend or two rock the jeep forward and back. Look at all the
rubber bushings in the control arms...there should be little to no movement
in the bushing from this small amount of force. Also check the track bars
for movement while your down there.

Every time I have a clunk on acceleration/deceleration, it's always
been my rear lower control arm bushings. It's hard to diagnose without
being able to watch from the outside while you "goose" the gas, to see
if there is slop in the bushings allowing the axle to rotate under
torque. I've just come to realize the stupid urethane bushings don't
last all that long, and it's something I'm going to have to change
about once a year.

If you have pro-comp or teraflex arms, I'd be willing to bet the
bushings are your source of the clunk/thunk.

Thanks for all this advice. I'll print this out and take it to a
mechanic. No better advice than experience. Thank you.

Stephjeff, if you read this, please respond, because both myself and
several others have been corresponding over the past months, and we
all share your health problem vis-a-vis monitors (as do many
undisclosed others).

There's a common culprit to all of our problems, which I can tell you
about including the science behind it, so if there's a way to reach
you please let me know!

:-)
