    I have a 2015 367 with the air trac suspension. Truck only has 33k mi the weird thing is I just noticed the rear ends dont line up the front is about a half inch to the driver side and the rear about half inch off to the passenger side I measured from the tire to the frame rail. The truck drives great no complaints. This can’t be normal?

    Has anyone changed tracking rods? Inspect for the spacers to be in the same location on each rod front to rear. It would be rare, but I have found them shimmed incorrect from the factory.

    You may have to run it to a alt. shop to have both rear ends lined up with ft. end, plus they will have a box of shims to get it right.
