Step 10.  The control arm is preset to the stock length.  If you are installing this part as a replacement for stock, no adjustment is necessary.  If the suspension is lowered from stock, adjustment IS required.  Loosen the jamb nuts for the adjuster on the control arm with your 1 ½” wrench.  A good starting point is 8 3/8” between the center of the mounting holes.  Another way to measure is to install the bolts, and measure from the outside edge on one bolt to the inside edge of the other.  This will be a good starting point when measuring pinion angle.  Tighten the jamb nuts.

 

Step 11.  Install the anti-clunk bushings into the UCA mounting bracket.  Install them on the outside of the bracket.

Step 12.  Install the UCA to the mounting bracket that you loosened in Steps 4 and 6.  Use the large metal washers on each side between the bushing and the mounting bracket.  Insert your bolt into the bracket and arm and attach the nut.  Leave it loose so you can pivot the arm when installing the rear bolt in step 14.

Step 13.  Loosely reinstall the two mounting bracket bolts that were removed in Step 4.  Try to realign it to the marks on the body and tighten the bolts.  There should not be much to adjust, but check it to be sure.  Torque to 85 ft-lbs.
