Tightening control arm pivot bolts?

Subject: Tightening control arm pivot bolts?
by NelsonV on 2015/2/27 20:43:15

A friend of mine brought up this issue; not something I've ever considered....

Quote:
A common error for a technician is to install a control arm, then torque the pivot bolt while still on the four-post lift. While on the lift, the suspension is at the end of its travel. If the technician torques the pivot bolt under those conditions, when the vehicle is lowered, the bushing will be in a constant twist. That condition is a death sentence to the bushing, one that may be carried out at the first good bounce of the suspension. That scenario is not an issue for polyurethane designs. Strut rod and radius arm bushings should be replaced in pairs to prevent great differences in caster between sides.
