How to torque Grand Am suspension & steering fasteners

Torque suspension and steering fasteners with the vehicle at ride height (wheels loaded) wherever a bushing is involved — tightening a control-arm or sway-bar bushing bolt with the suspension hanging pre-loads the rubber and it fails early. Clean the threads, start every fastener by hand to avoid cross-threading, and make the final pass with a calibrated torque wrench rather than an impact gun. Ball-joint and tie-rod castle nuts take a new cotter pin; never back a castle nut off to line up the hole — only tighten to the next slot.
