Best thing I can tell you is to use some white lithium grease and a rubber mallet to help smooth the install into rack. To ease installation under car, I pulled the 2 sleeves out from the k-member. You hold the rack up and then drive the sleeves back through the rack and into the k-member. Book says torque nuts to 42-62 ft lbs. Oh and the bushing holes should be turned towards the bottom of the rack. Should only take an hour, 2 tops.
