9. Locate the OE cross member that was removed earlier.

Measuring from the leading edge on the driver side, scribe a mark at 4 3/4” and 8 1/4”. Measure from the bottom of the cross member up 1/4” and scribe a mark. Now measure from the back of the cross member 2” and scribe a mark.

6. Carefully remove the hardware holding the (4) front differential mounts to the OE location and discard the hardware.

7. Carefully lower down on both hydraulic floor jacks allowing enough room for the spacer washers to be installed.

7/16” unitorque nuts from hardware bag 14059NB. Install the new spacer washers to drop the differential down and secure using the new 7/16” hardware. Make sure to use loctite and torque to 42 ft lbs. Remove the hydraulic floor jacks from under the front differential.

10. Using a die grinder, carefully notch out the OE cross member following the lines that were scribed earlier.

12. Working on the driver side, remove the ABS line from the bracket on the top of the upper control arm pocket. Now disconnect the ABS lines from each other at the quick disconnect. Special note: Take special care not to damage ABS line during removal.

22. Locate (4) SERT04 from hardware bag 14059NB. Install the new sert fittings to the new upper control arm. Special note: Take special care not to cross thread during installation and make sure not to over tighten. Hand tighten with an end wrench. Also, make sure that once installed the sert fitting is facing the outside of the vehicle so it will be easy to access with a grease gun.

21. Locate the new upper control arms. Locate (8) poly bushings and (4) sleeves from hardware bag 14059PL.

Install the new bushings and sleeves into the new upper control arms. Special note: Make sure to use a fair amount of lithium or moly base grease before installing the new bushings and sleeves into the control arms. This will increase the life of the bushing as well as help prevent squeaking.

Now install the new cotter pin.

Special note: Using a pry bar to gain leverage will help installation easier. Also, If the new cotter pin can not be installed because the hole in the new castle nut does not line up with the new ball joint, DO NOT loosen the new castle nut so that the cotter pin can fit, tighten the new castle nut some more so that the new cotter pin can be installed.

Repeat procedure on the passenger side.

29. Locate (2) 6 mm flat washers and (2) 6 mm unitorque nuts from hardware bag 14059NB. Working on the driver side, reconnect the ABS lines back together.
