I am new to the forum and recently got a Mach1. I am also new to the technical part of repairs. When I inspected my suspension, I found 1 upper and 1 lower ball joint sleeve leaking grease and planned on getting a rebuild kit for both upper and lower ball joints with the lower attached to the control arm, the outer tie rods, and strut and sway bar bushings. Any benefit to using a tubular lower control arm?
