CAUTION: Do not pry on the cam or thrust spacers during removal. Prying may damage the cam or spacers.

7. Using a magnet, remove the locking key.

CAUTION: To prevent damage to the threads of the front wheel spindle, look into the keyway of the front wheel spindle under the adjusting nut and remove the separate locking key before removing the adjusting nut.

9. While rotating the hub and rotor assembly, tighten the wheel bearing adjusting nut to 47 Nm (35 ft. lbs.) to seat the wheel bearings. Spin the rotor and back off the nut one-quarter turn (90 degrees).
10. Retighten the adjusting nut to 1.8 Nm (16 inch lbs.) using a torque wrench.
11. Make sure the final end play of the wheel on the front wheel spindle is 0.00-0.08 mm (0.000-0.003 inch). The maximum torque to rotate the hub is 2.8 Nm (25 inch lbs.).
12. Align the closest lug in the wheel bearing adjustment nut with the center of the keyway slot of the front wheel spindle. Advance the nut to the next lug if required. Install the separate locking key in the keyway of the front wheel spindle under the adjusting nut.

WARNING: EXTREME CARE MUST BE TAKEN WHEN ALIGNING THE NUT OF THE FRONT WHEEL SPINDLE ADJUSTMENT LUG WITH THE CENTER OF THE KEYWAY SLOT OF THE FRONT WHEEL SPINDLE TO PREVENT DAMAGE TO THE SEPARATE LOCKING KEY. THE WHEEL AND TIRE ASSEMBLY MAY COME OFF WHILE THE VEHICLE IS IN MOTION IF THE KEY IS DAMAGED.
