Hey I've got a 98 ZJ with a 4 inch lift. The front track bar is stock. The problem that I am having is if i hit the wrong bump at speeds less than 40 mph or get a little bit of snow in the rims I get a massive front end shake like a death wobble. i have tightened the track bar as much as i can but with no remedy. anyone having the same problem and got a good tip to fix this problem?
