heres the thing i actuley know how to check the parts for wear on these trucks and i have found bad parts that other good techs could not find.
you guys do whatever you want to your trucks i really could care less.
i work at a ford dealership and heres where the listing for cranking the t-bars in the ford shop manual is under contents/index, then to (group 04) 4x4 suspension (SECTION 204-01B), then theres a little link called ride height, which gives you bob's exact instruction (not word for word but close enough) and no where in the manual does it say anything about loosening the upper arm
but hey what do i know i only work there and look at the manual every day
