Your GM 8-Lug vehicle is known to have a front bushing problem in the lower control arm. To prevent this problem from causing more problems further down the road, we request that the problem be fixed now. It will cause problems on some lift systems, mainly that use a linkage as our Cognito 4-6" and 10-12" non torsion bar drop lift systems. As shown in figure 1.1, the front bushings work themselves out of the lower control arms. The solution is to press out the front bushing and press it back in from the other direction. Instead of the bushing being pressed in from the front of the truck toward the back, the bushing will be pressed in from the back of the truck toward the front. Perform this task now with the proper tools before assembling the control arms back into the vehicle. As shown in the figure, the bushing flange is on the left. When you are finished swapping the bushing, the flange will be on the right. This will keep proper location of the lower control arm and bushing which will keep proper positioning of the linkage system of this lift kit.
