installed upper control arm to the OE knuckle and secure
using the new castle nut. Make sure to use loctite and torque
to 40 ft lbs. 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.

front differential using the OE hardware. Make sure to use
