AnswerHUB AND BEARING (FRONT)
REMOVAL
Raise vehicle on jackstands or centered on a frame contact type hoist. See Hoisting in the Lubrication and Maintenance section of this manual, for the required lifting procedure to be used for this vehicle.
Remove the front wheel and tire assembly from the vehicle.
Remove the 2 guide pin bolts mounting the caliper assembly to the steering knuckle Disc Brake Caliper Mounting Remove the caliper from the front steering knuckle. Refer to Disc Brake Caliper in the Removal And Installation Section in the Brake Group of this MDS2 for the caliper removal procedure
Remove rotor from hub by pulling it straight off wheel mounting studs Removing Rotor
Remove the hub and bearing retaining nut Hub And Bearing Retaining Nut
Remove the 3 hub and bearing assembly to steering knuckle attaching bolts Hub And Bearing Assembly Retaining Bolts
CAUTION: When removing hub and bearing assembly from steering knuckle, be careful not to damage the flinger disc Hub And Bearing Assembly Seal on hub and bearing assembly. If flinger disc becomes damaged, hub and bearing assembly MUST not be used and MUST be replaced with a new hub and bearing assembly.
Remove hub and bearing assembly from steering knuckle, by sliding it straight out of steering knuckle and off end of stub axle Hub And Bearing Removal And Installation If hub and bearing assembly will not slide out of knuckle. Insert a pry bar between hub and bearing assembly and steering knuckle Prying Hub And Bearing Assembly From Steering Knuckle and gently pry hub and bearing from knuckle. If stub shaft is frozen to hub and bearing assembly tap end of stub shaft with soft face hammer to free it from hub and bearing spline
CAUTION: If metal seal Hub And Bearing Assembly Seal on hub and bearing assembly is seized to steering knuckle and becomes dislodged on hub and bearing assembly during bearing removal. The hub and bearing assembly MUST not be reused and MUST be replaced with a new hub and bearing assembly
INSTALLATION
CAUTION: Hub and bearing assembly mounting surfaces on steering knuckle and driveshaft Hub And Bearing Mounting Surfaces must be smooth and completely free of foreign material or nicks
CAUTION: When installing hub and bearing assembly into steering knuckle, be careful not to damage the flinger disc Hub And Bearing Assembly Seal on hub and bearing assembly. If flinger disc becomes damaged, hub and bearing assembly MUST not be used and MUST be replaced with a new hub and bearing assembly.
Install hub and bearing assembly onto stub shaft and into steering knuckle until squarely seated on face of steering knuckle.
Install the 3 hub and bearing assembly to steering knuckle attaching bolts Hub And Bearing Assembly Retaining Bolts Equally tighten all 3 mounting bolts until hub and bearing assembly is squarely seated against front of steering knuckle. Then tighten the 3 hub and bearing assembly mounting bolts to a torque of 110 N·m (80 ft. lbs.)
CAUTION: The hub and bearing assembly to stub shaft retaining nut Hub And Bearing Retaining Nut is a prevailing torque nut and can not be re-used. A NEW retaining nut MUST be used when assembled.
Install a NEW hub and bearing assembly to stub shaft retaining nut Hub And Bearing Retaining Nut Tighten, but do not torque the hub nut at this time.
Install the rotor on the hub and bearing assembly Removing Rotor
Install front brake caliper back over braking disc and align with caliper mounting holes on steering knuckle. Refer to Disc Brake Caliper in the Removal And Installation Section in the Brake Group of this MDS2 for the caliper installation procedure. Install the caliper to steering knuckle guide pin bolts Disc Brake Caliper Mounting and tighten to a torque of 19 N·m (168 in. lbs.)
Install wheel and tire assembly on vehicle. Tighten the wheel mounting stud nuts in proper sequence until all nuts are torqued to half specification. Then repeat the tightening sequence to the full specified torque of 129 N·m (95 ft. lbs.)
Lower the vehicle to the ground
CAUTION: When torquing hub and bearing assembly to stub shaft retaining nut, do not exceed the maximum torque of 163 N·m ± 14 N·m (120 ft. lbs. ± 10 ft. lbs.) If the maximum torque is exceeded this may result in a failure of the drive shaft.
With vehicle brakes applied to keep vehicle from moving, tighten the NEW stub shaft to hub and bearing assembly retaining nut to 163 N·m ± 14 N·m (120 ft. lbs. ± 10 ft. lbs.) Torquing Hub And Bearing Retaining Nut
Check the Toe setting on the vehicle and reset if not with-in specifications.
