68 Barracuda Front Suspension Rebuild Kit

I jack up from lower control arm, place jack stand under frame rail for safety, keep jack under control arm and jack stand under frame rail (not touching) frame rail. Remove tire and then separate UCA from spindle. You may need a wire to keep spindle assembly from tugging on your brake line. Torsion bar stays at set adjustment.
he doesn't need to separate the the UCA and spindle. just pull the assembly out from the mount and adjust the rod ends, and knock it all back together.

personally, i pull the tension off the t-bars when working on the suspension, but i guess that's a personal judgement call as to what your individual level of risk acceptability is.
