17. Raise the control arm into you desired lower location and install using the supplied M 14 x 100mm bolt and nylon nut.

20. Slide the drivers side bracket up into place over the stock mounting bracket.

21. Insert one of the 100mm long bolts through the panhard rod mounting hole and panhard rod. Using the stock flag nut make sure it is pointed down like shown and keep loose for now.

23.    Like the passenger side insert the M14 x 100mm long bolt through the bracket and long support sleeve where the stock control arm was originally mounted. Install the nut loosely
24.    Rotate the control arm up into the relocation bracket into desired hole and install the M 14 x 100mm long bolt and nut.
25.    Torque the two M12 x 30mm bolts on the drivers and passenger side brackets to 47 lb/ft.
26.    Torque the drivers side panhard rod and the passenger side rear upper support bolt to 129 lb/ft.

27.    If using stock or bonded control arm bushings lower the vehicle to the ground and torque the remain­ing 4 mounting bolts to 129 lb/ft. Don't forget to torque the chassis side control arms if you loosened them.
28.    With non bonded control arms you can torque everything in the air without creating bind.
