1. Remove the boots prior to installation to prevent damage. Do not forget to reinstall
them prior to installing the knuckles
2. Orient the lower ball joint so the grease fitting is pointing forward when installing.
3. Install the ball joints using the factory service manual as a guide. Torque the lower
ball joint nut to 35 ft-lbs, and then tighten the upper ball joint nut to 70 ft-lbs. Further
tighten to align the cotter key hole on the upper ball joint, do not loosen to align the
cotter key.
4. Re-torque the lower ball joint nut to 140-160 ft-lbs, again further tighten to align
cotter key hole.
5. Wait until the ball joints are installed to install the grease zerk fittings.
6. Recheck caster on vehicle after new ball joints have been installed as worn ball joints
could result in an increase in actual caster due to excessive play.
