I have just recently put on a 3.5 inch rubicon express lift kit and the guy i bought it from had an after market track bar. So i installed it and now every time i turn the wheel the track bar at the lower end moves what should i do?

 

How much does it move?
Is it properly torqued?
Mine did this after i install it and i retorqued it and have not had a problem. If this doesn't fix it, the mounting hole might be wollered out.

 

it moves a little bit, and i didnt know the tourque specs do i just tightend it till i felt it was tight, but i think your right about the hole i think its not very tight in there.
