Double check your u-joints. If it pops when putting it in gear then have someone shift it while you watch underneath. Obviously not directly under the vehicle.

I dont think its the exhaust I will look though at this point im willing to check anything causing it, would a ball joint pop like that when shifting into drive im moving all the weight of the vehicle forward would a ball joint pop like that, when it pops I can feel it under my left foot left of the brake pedal under the vehicle.

I don't think ball-joints would would clunk like this in an XJ. They are easy to check just by jacking up your Jeep just high enough so that the tires clear the ground. Grab your tires at the top and bottom (without putting you fingers under the tire) and see if you can move the tire-wheel in a push pull movement. If you have play there your ball joints or unit hub are bad.

It seems to me this is really a control arm issue either axle or body side bushings. They don't need a lot of play in them to make a clunk that is heard and felt from the floorboard.


As Crispynuggets has pointed out bad u-joints on either the front or rear drive shafts could cause a clunk like this that may be transmitted to the floorboard.

ok, no the u-joints are out of the driveshaft I bought from a salvage yard, I replaced some centering piece inside the front driveline it the u joints looked ok, I dont know how to tell if they are bad or not, they have grease in them and they seemed to be smooth, but I think I will start there and replace the u joint in the shafts, can the TRAC-BAR make this noise?? like the ball joint end of the track bar it connects to the frame and almost sounds like it could be coming from there.

Ya it could. You could have someone move the steering wheel back and forth while you inspect the front end. Check tie ends, pitman arm, and the track bar for play. There should be no play. If there is slop in any component replace it.
