Locking Hubs: Installation
- To install, reverse removal procedure. Apply sealant to contact areas between locking hub assembly and hub/rotor assembly. Ensure sealant is NOT applied on outer areas of hub/rotor assembly toward brake contact areas.
- Align locking hub assembly key area with steering knuckle key way area. Loosely install locking hub assembly on hub/rotor assembly. Ensure locking hub assembly fully contacts hub/rotor assembly.
- Install locking hub retaining bolts. Tighten bolts to 36-43 ft. lbs. (49-58 N.m). Using spring scale attached to wheel stud, measure turning resistance required to rotate hub/rotor assembly.
- Turning resistance should NOT exceed 3.1 lbs. (1.4 kg). If turning resistance exceeds specification, check for incorrect installation of locking hub assembly or components.
- Install shim and snap ring on drive axle. Rotate drive axle until maximum end play is obtained. Using a dial indicator, check drive axle end play.
- Drive axle end play should be .008-.020" (.20-.51 mm). If axle end play is NOT within specification, adjust end play by changing axle shaft shim. Install hub cover. Tighten hub cover 13-25 ft. lbs. (18-34 N.m).
