Disassembly and Reassembly

Disassembly






Notice:
^ Do not remove the dust cover unless necessary for repairs.
^ Do not confuse the inner bearing with the outer bearing.

1. Remove the knuckle assembly.





2. Remove the wheel hub assembly by using the SST.





3. Remove the outer bearing, outer oil seal, outer bearing race and spacer from the wheel hub by using the SST.

Caution: Hold the hub to prevent it from falling.

4. Discard the oil seal, regardless of condition.
5. Disassemble the knuckle assembly.

Notice: Remove the race gradually and carefully.

6. Remove the oil seal (inner) with a screwdriver.
7. Remove the wheel bearing (inner).





8. Remove the bearing race (inner) with the SST and a hammer.

Caution: Tap on the bearing race (inner) only.

Caution: Do not remove the dust cover if it is not necessary. Do not reuse the dust cover if it is removed once.





9. Mark the dust cover and knuckle for the proper reassembly.
10. Remove the dust cover with a chisel.

Inspection
Wash the disassembled parts before inspecting.
Replace any damaged parts. Minor rust should be removed with a fine sandpaper.

Inspect for:
1. Abnormal wear, damage or seizure of bearing.

Notice: Replace the bearing as a set (inner and outer races).

2. Cracks or damage of the knuckle. Scoring or rust of the bearing bore.





3. Damaged dust cover or poor fit with knuckle.





4. Cracks or damage of the hub. Scoring or rust of the bearing bore. Wear at the oil seal contact surface.

Assembly

Notice: If the bearings or knuckle have been replaced, the bearing preload must be checked before assembly.





1. If the dust shield was removed, install a new one by using the Dust Shield Replacer or equivalent.





2. Install the bearing races in the steering knuckle.





3. Pack the bearings with the Lubricant lithium grease. Pack the hub area as shown in the figure.





4. Place the inner bearing into the steering knuckle bore so that it rests in a level position.





5. Lubricate the lip of the new inner oil seal. Apply a sufficient amount of lubricate to the cutting parts along the edge of seal lip.





6. Install the new inner oil seal in the bore.
7. Place the original bearing preload spacer, or the spacer selected from the bearing preload check procedure in the steering knuckle bore.
8. Position the outer bearing in the steering knuckle bore.
9. Lubricate the lip of a new outer oil seal.
10. Install the new outer oil seal in the steering knuckle bore.
11. Install the knuckle assembly.





12. Use the SST and position the wheel hub assembly in the steering knuckle bore.

Adjustment of wheel bearing preload





1. Insert the two wheel bearings and removed spacer into the steering knuckle and attach the SST.
2. Secure the bottom of the SST.





3. Tighten the nut of the SST to the specified torque.
Tightening torque: 116 - 173 ft. lbs. (157 - 235 Nm, 16 - 24 kg-m)

Caution: When tightening, tighten it with 49 Nm (5 kg-m, 36 ft. lbs.) step by step to prevent applying the excessive preload.

4. Rotate the steering knuckle to seat the wheel bearings.





5. Measure the wheel bearing preload with the SST and a pull scale.
Wheel bearing preload:
2.17 - 10.41 inch lbs. (0.25 - 1.17 Nm, 2.5 - 12 kg-cm) 0.55 - 2.64 lbs. (2.5 - 11.7 N, 0.25 - 1.2 kg) (pull scale reading)





6. If the preload is not within the specification, select the proper spacer from the table to adjust it.
Notice: Increase the spacer thickness to reduce the preload and decrease it to increase the preload when a spacer is changed by 1 rank, the preload changes 0.2 to 0.4 Nm (2.0 - 4.0 kg-cm, 1.7 - 3.5 inch lbs.) The rank marking is stamped on the outer periphery of the spacer.





7. Remove the SST.
Wheel bearing (outer & inner), oil seal (outer), and spacer

Notice: Completely fill the shaded area shown in the figure with a lithium grease.
