Locking Hubs: Installation

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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).
