I've been having this problem ever since I purchased this 04 tj 4.0. When ever I do a hard acceleration from a stop mostly in first gear there is a loud clunk noise. It also happens when letting off the gas from high acceleration in first gear and is a lot more noticeable. I can get it to do it in second gear too. If I accelerate and decelerate in quick secession in first, it clunks in quick secession. Manual tranny 5 speed.
Things I have done to rid this issue and because it needed done....
New hubs
New front axle u-joints
New front and rear drive shaft u-joints
New steering knuckles
New poly transmission mount
All new control arms with all new bushings
New sway bar links with bushings
Sway bar bushing front and back
New springs
New shocks
All new steering linkage
All new ball joints
New rear track bar and bushings
New flywheel, clutch (Mechanic did this job)
Front and rear diff service
Tranny fluid service Mt-90
Body and engine mounts don't look bad
I do have a 4wd cable shifter yet to install.
Everything I did is torqued to spec.
Everything is stock except rancho shocks, rims and tires.
ANY ideas will be much appreciated. Thank you In advance.
