FRONT WHEEL BEARINGS
The following procedures for hub and wheel bearing removal and installation require the use of many special tools and a hydraulic press. Do NOT attempt this procedure without the special tools. The following tools, or their equivalents, are recommended by Acura for removing and replacing wheel bearings:
No.07HAD-SG00100: driver attachment
No.07746-0010500: wheel bearing driver attachment
No.07GAF-SD40700: hub assembly base
No.07GAF-SE00100: hub assembly tool
1. Pry the lock tab away from the spindle and loosen the nut. Slightly loosen the lug nuts.
2. Raise and safely support the vehicle. Remove the front wheel and spindle nut.
3. Remove the wheel sensor from the knuckle, but do not disconnect it.
4. Remove the caliper mounting bolts. Hang the caliper out of the way with a piece of wire.
5. Remove the brake rotor retaining screws. Screw both 12mm bolts into the disc brake removal holes and turn the bolts to press the rotor from the hub. Only turn each bolt 2 turns at a time to prevent cocking the disc.
6. Remove the tie rod from the knuckle using a tie rod end removal tool. Use care not to damage the ball joint seals.
7. Remove the cotter pin from the lower arm ball joint and remove the castle nut.
The lower ball joints cannot be separated from the steering knuckle
8. Remove the lower control arm from the knuckle using the ball joint removal tool.
9. Remove the cotter pin from the upper arm ball joint and remove the castle nut.
10. Remove the upper arm from the knuckle using the ball joint remover.
11. Remove the knuckle and hub by sliding the assembly off of the halfshaft. Be sure to clean any dirt or grease off of the ball joints.
12. The hub can be removed with a slide hammer. Clamp the knuckle in a vise and secure the slide hammer to the wheel studs.
13. Remove the splash guard and snaprings.
14. Support the knuckle and press the bearing out towards the wheel side.
15. If the inner bearing race stayed on the hub, use a puller to remove it.
16. Clean all parts and examine for wear and damage.
17. When pressing in a new bearing, install the inner snapring first and press the bearing in from the wheel side. Be sure to press only on the outer race or the bearing will be damaged.
18. Install the outer snapring and the splash guard.
19. Properly support the knuckle and press the hub into the bearing. Do not press on the wheel studs or they will press out of the hub. Support the knuckle by the inner race or the bearing will be damaged. Be sure to lubricate the bearings.
20. Install the knuckle/hub/bearing assembly onto the halfshaft and reassemble the knuckle to the upper and lower control arms.
21. Tighten the lower ball joint nut to 51-58 ft. Lbs. (70-80 Nm) and tighten further, if necessary, to install a new cotter pin.
22. Tighten the upper ball joint nut to 29-35 ft. Lbs. (40-48 Nm) and tighten further, if necessary, to install a new cotter pin. Tighten the tie rod end to 36-43 ft. Lbs. (50-60 Nm) and tighten further, if necessary, to install a new cotter pin.
23. Install the disc brake rotor, caliper, mounting bolts, and brackets. Reconnect the wheel sensor bracket to the knuckle.
24. With the wheel installed and all 4 wheels on the ground. Tighten the spindle nut to specifications, then stake the nut in place.
FRONT BRAKE ROTORS
1. Use a siphon or clean turkey baster to remove about half of the brake fluid from the master cylinder.
2. Raise and safely support the vehicle and remove the tire/wheel assembly.
3. Remove the caliper guide pin or mounting bolts.
4. Lift the caliper assembly away from the brake rotor.
5. Use a suitable piece of wire to suspend the caliper assembly from the upper control arm. This will prevent the weight of the caliper from being supported by the brake flex hose which will damage the hose.
6. If equipped, remove the rotor retaining screws.
7. Remove the brake rotor by pulling it straight off the wheel mounting studs.
8. If installing the rotor on the rear brakes, use a commercially available locknut wrench, or equivalent tool, to turn the caliper piston clockwise into position in the cylinder, then align the cutout in the piston with the tab on the inner pad by turning the piston back.
9. If installed the rotor on the front brakes, completely retract the piston into the caliper using a large C-clamp or other suitable tool.
10. Install the brake rotor onto the wheel hub.
11. Install the caliper assembly over the brake rotor and install the guide pin or mounting bolts.
12. Fill the master cylinder to the proper level with fresh brake fluid.
13. Install the tire/wheel assembly and lower the vehicle.
14. Pump the brake pedal until the brake pads are seated and a firm pedal is achieved before attempting to move the vehicle.
Do not move the vehicle until a firm pedal is obtained.
15. Road test the vehicle to check for proper brake operation.
