A:With reference to your inquiry on the Dorman - OE Solutions Suspension Control Arm and Ball Joint Assembly - part# 521-145, jack up one side at a time, put a jack stand under frame, one under axle, leave jack under center of rear end, let weight of truck down onto jack stands, jack back up a little for extra safety,take wheel off for extra room.
