Looking for help ,I have a 2001 tj 4" lift running 35" procomp all terrains . Some history to my problem about a month ago started getting a small shake about 40 mph every now and then. In the past I could rotate tires and everything good again this time I rotated tires the shake got very bad at 45 mph. Checked alignment ,it was out about 1/4 inch set toe back in a 1/16 checked all front end and bearings had tires balanced still bad shake at 45 . I have now rotated tires every possible way and still have the shakes anywhere from 40 to 50 mph . So scratching my head trying not to blow it up have checked and rechecked front end components any help would be appreciated thanks.
