Raise vehicle high enough so that both rear wheels are off the ground and support the vehicle under the frame. NOTE: Do not support under the axle. Using 18mm wrenches, remove both control arm bolts and then remove the control arm. If using an adjustable version of control arms, adjust the arms to the factory length using the OE control arms as a guide. Once properly adjusted, apply Loctite blue to the threads and tighten the jam-nuts. If a custom length is desired, the control arms may be adjusted after the installation however an alignment is recommended to confirm side-to-side consistency. If using polyurethane bushings, lube the external bushing surfaces of the new control arms. If using rod-end equipped control arms install the control arms and tighten the bolts to 90 ft. /lbs. If using polyurethane equipped control arms leave the bolts loose until the vehicles’ weight is resting on the control arms
