Ok i have my truck in the air.. im stuck on the back part., i have the new leaf spring in. now do i have to tighten that new center bolt all the way or to a certain torque...
The torque spec for the center bolt is not that critical. When I put my leaf pack pack together, I just snugged down the center bolt with a box end wrench. The u-bolts do the majority of the holding anyways.
