Note. Front axle ball joint adjustment is only necessary when there is excessive play in steering, irregular wear on tire or persistent loosening of tie rod.

Scheme 22

1. Raise and support vehicle. Remove wheel and tire assembly. Install Axle Shaft Boot Seal Protector (J-28712) on axle shaft boot to protect boot during repair. Depress brake caliper piston, detach brake caliper and wire aside. Remove brake rotor.

Support lower control arm using floor jack or jackstand. CAUTION: Support lower control arm with floor jack or jack stand to maintain tension on torsion bar.
4. Remove cotter pins from ball joint studs. On "T" Series, place Ball Joint Separator (J-34026) over upper or lower ball joint. (Scheme 23) Loosen ball joint nut. Back off until nut contacts ball joint separator. Continue backing off nut until nut forces ball stud out of steering knuckle.
