There is a bulletin for the rear upper control arm (3-13-5) if the rear camber is beyond spec when checking the alignment. We need to make sure the vehicle has not been hit and the sub frame or suspension components are bent. If just one side is way out it could cost 2hrs to install the kit.
this is the kit part # XXXXX and it goes for 240$ off the internet Ford parts. The local dealer will ask more. If you get the vehicle alignment checked let me know what it is.
