Some sad news…
While installing the new rear upper arm and rear toe link, I discovered the rear trailing arm got twisted when the upper arm broke.
While visually it looks within spec to a spare arm I had lying around, it only takes a few hundredths here or there to affect the alignment. Sure I could adjust it out with the upper and toe arm, however, given the force/stress the arm saw, I’d rather not risk using it again. I’ve asked Chase to order a new arm and I’ll be creating a new template for the welded rear box structure. It’s amazing how much work Mark and Fosstech did on these arms.
