Added X5 ball joints and bumpsteer kit to correct front geometry. Went for alignment today and needed a 4 wheel? Both adj. LCAs were within 1 mm in length when I installed them but when on the rack it showed rear toe (RR out, LR in) off by .74 degrees. Apparently this is a lot for pinion angle and tracking. Said it had to be done before fronts could be set. Anyone else had to do this. Also what are the factory specs for toe and camber?
