24. 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.
25. 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.
26. Locate (6) 3/8” nylon lock nuts and (6) 5/16” USS flat
washers from hardware bag 14059NB. Working on the driv-
er side, install the newly modified strut into the upper loca-
tion and secure using the new hardware. Make sure to use
loctite and torque to 35 ft lbs. Repeat procedure on the pas-
senger side.
