Wheel Hub: Service and Repair
REMOVAL1. Hoist vehicle and remove wheel.
2. Remove axle shaft drive flange (4WD vehicle) or hub cap (2WD vehicle).
3. If equipped with ABS, remove wheel speed sensor from knuckle and harness clamp from strut.
4. Remove caliper bolt and suspend caliper.
CAUTION: Hang removed caliper with a wire hook of the like so as to prevent brake hose from bending and twisting excessively or being pulled. Don't operate brake pedal with pads removed.
5. Remove brake disc.
NOTE: If brake disc cannot be removed by hand, use 8 mm bolts as shown.
6. Remove front wheel bearing lock washer by loosening 4 screws.
7. Remove front wheel bearing lock nut by using special tool.

8. Remove front wheel bearing washer.
9. Remove wheel hub complete with bearings and oil seals.
NOTE: If wheel hub can not be removed by hand, use special tools as shown.
Special Tool
(B): 09943-35511
(C): 09942-15510
10. Remove sensor rotor from wheel hub as shown (if equipped with ABS).
CAUTION: Pull out sensor rotor from wheel hub gradually and evenly. Attempt to pull it out partially may cause it to be deformed.
11. Remove oil seals.
12. Remove bearing circlip.
13. Using hydraulic press and drift, remove bearing race.
14. Remove hub bolts from hub.
INSTALLATION
1. Insert new stud in hub hole. Rotate stud slowly to assure serrations are aligned with those made by original bolt
2. Using special tools, press-fit bearing outer race until its end contacts stepped surface of wheel hub.
Special Tool
(D): 09944-68210
(E): 09924-74510
3. Install front wheel bearing.
NOTE:
- As front wheel bearing is cassette type double taper roller bearing, it must be replaced as whole unit when replacement becomes necessary.
- Cassette type double taper roller bearing is so designed as to provide proper pre-load as long as it is tightened to specified torque. Therefore, it requires no pre-load check after installation, unlike conventional taper roller bearing.
- Apply wheel bearing grease between bearings.
"A": Grease 99000-25010
4. Install bearing circlip.
5. Drive in oil seals by using special tools.
Special Tool
(F): 09944-66010
(G): 09924-74510
6. Apply lithium grease to lip portion and hollow of oil seal.
NOTE: Amount of grease applied to hollow in oil seal should be more than 60% of its vacant space.
"A": Grease 99000-25010
7. Install sensor rotor as shown (if equipped with ABS).
NOTE:
- Pipe used here should have inner diameter of 100 mm (3.94 inch.) - 106 mm (4.17 inch) and its outside should not contact teeth of sensor rotor.
- Use care not to insert wheel hub diagonally.
8. Install wheel hub complete with bearings and oil seals onto front wheel spindle.
9. Install bearing washer.
10. Tighten wheel bearing lock nut to specified torque while turning wheel hub by hand.
Special Tool
(A): 09951-16050
Tightening Torque (a): 216 Nm (21.6 kg-m, 157 ft. lbs.)
11. Using lock washer, lock bearing lock nut. If lock screw hole is not aligned with screw hole in lock nut, turn lock nut in tightening direction till they align.
Tightening Torque (b): 1.5 Nm (0.15 kg-m, 1.1 ft. lbs.)
12. Apply lithium grease to front spindle thrust washer and front wheel spindle outer.
13. Install circlip to drive shaft and drive flange to wheel hub.
14. If equipped with ABS, install front wheel speed sensor and harness clamp.
Tightening Torque
(c): 23 Nm (2.3 kg-m, 17.0 ft. lbs.)
(d): 10 Nm (1.0 kg-m, 7.5 ft. lbs.)
15. Install brake disc and caliper assembly.
Tightening Torque (e): 85 Nm (8.5 kg-m, 61.5 ft. lbs.)
16. Apply sealant and install axle shaft drive flanger or hub cap.
For 4WD vehicle:
Apply sealant mating surface of axle shaft drive flange, then install axle shaft drive flange and tighten flange bolt to specified torque.
Tightening Torque (f): 48 Nm (4.8 kg-m, 35.0 ft. lbs.)
"A": Sealant 99000-31090
For 2WD vehicle:
Remove grease, old sealant and dusts from mating surfaces of hub cap and hub to clean, apply water tight sealant to cap mating surface evenly, and install cap to hub.
"B": Sealant 99000-31090
17. Install wheel.
Tightening Torque (a): 95 Nm (9.5 kg-m, 69.0 ft. lbs.)
