32. Locate (4) SERT04 from hardware bag 14056NB1.
Install the new sert fittings to the new upper control arm.
Special note: Take special care not to cross thread dur-
ing 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 vehi-
cle so it will be easy to access with a grease gun.
33. Working on the driver side, install the new upper control
arm into the OE location using the OE cam bolts. Do not
tighten at this point. Repeat procedure on the passenger
side.
34. Locate the OE struts and upper hardware. Install the OE
nuts back to the upper studs of the strut. Using a die grinder,
carefully cut off the nipple part of the studs. Special note:
Take special care not to cut into the threads. If by
chance you do cut into the threads, once you remove
the OE nuts the threads will be fixed. Once the nipples
have been cut off, remove the OE nuts from each stud.
35. Locate the new upper strut spacers. Install the new spac-
ers to the OE struts and secure using the OE hardware.
Make sure to use loctite.
36. Locate (6) 3/8” nylon lock nuts and (6) 5/16” USS flat
washers from hardware bag 14056NB2. Working on the driv-
er side, install the newly modified strut into the upper location
and secure using the new hardware. Make sure to use loc-
tite and torque to 35 ft lbs. Repeat procedure on the pas-
senger side.
