I have a short wheel base 89 F150 4x4 with a 351 4" suspension lift and 33"x12.50" tires. Here lately when I hit the brake I get wheel wobble really bad, it also happens sometimes when I hit a bump. I am trying to find out what could be causing this. Lower ball joints are new. Any info would be much appreciated. Also I don't see a steering stabilizer under my truck. Is that normal?
