Greasing the Wheel Bearings1. Remove the outboard bearing and bearing racefrom the hub (Figure 35).g033050Figure 351. Seal 4. Bearing cavity (hub)2. Inboard bearing 5. Outboard-bearing race3. Inboard-bearing race 6. Outboard bearing2. Remove the seal, inboard bearing from the hub(Figure 35).3. Wipe clean the seal and check for wear anddamage.Note: Do not use cleaning solvent to clean theseal. Replace the seal if it is worn or damaged.4. Clean the bearings and races, and check theseparts for wear and damage.Note: Replace all worn or damaged parts.Ensure that the bearings and races are cleanand dry.5. Clean the cavity of the hub of all grease, dirt,and debris (Figure 35).6. Pack the bearings with the specified grease.7. Fill the cavity of hub 50 to 80% full of thespecified grease (Figure 35).8. Assemble the inboard bearing onto the race atthe inboard side of the hub and install the seal(Figure 35).9. Repeat steps 1 through 8 to the bearings for theother hub.Installing the Hub and Rotor1. Apply a light coat of the specified grease to thespindle (Figure 36).g192344Figure 361. Nut retainer 4. Outer bearing2. Spindle nut 5. Hub, rotor, inner bearing,race, and seal3. Tab washer 6. Spindle2. Assemble the hub and rotor onto the spindlewith the rotor inboard (Figure 36).3. Assemble the outboard bearing onto the spindleand seat the bearing to the outboard race(Figure 36).4. Assemble the tab washer onto the spindle(Figure 36).5. Thread the spindle nut onto the spindle andtighten the nut to 15 N∙m (11 ft-lb), while rotatingthe hub to seat the bearing (Figure 36).6. Loosen the spindle nut until the hub rotatesfreely.7. Torque the spindle nut to 170 to 225 N∙cm (15to 20 in-lb).8. Install the retainer over the nut and check thealignment of the slot in the retainer and the holein the spindle for the cotter pin (Figure 37).Note: If the slot in the retainer and the hole inthe spindle are not aligned, tighten the spindlenut to align the slot and hole to a maximumtorque of 226 N∙cm (20 in-lb) on the nut.34
