07 9-7x 5.3. Had noticed a front end vibration at 70+ and an occasional slight pull to the left only when braking so I took it to a trusted shop. They said my right upper control arm bushings and ball joint were bad so they replaced the UCA. Truck immediately pulled hard to the right. Tire even squealed driving straight. Took it to another shop for alignment (1st shop didn't have a rack), and they were able to stop the pull when driving, but were not able to get the alignment within spec. AND it now pulls very hard left when braking. Any thoughts? (yes, they verified the settings were correct for 9-7x and not the model named in the paperwork).
