I have a 99 XJ with stock suspension and I have a front passenger side tire bounce at around 70mph. The mechanic said the driver side front tire is about 1/2 inch back further than the passenger side. I have replaced rims and tires, front end alignment, lower control arms, steer damper, upper and lower ball joints, tie rods, track bar, axle u joints, wheel bearings, sway links, and everything else related. Can that 1/2 inch make the tire bounce? I'm running out of ideas. Thanks in advance.
