9. Fit the inner race and cage, and assemble the six bearing balls in the outer shaft.

Pack molybdenum disulphide lithium base grease in the outer shaft without fail.

10. Install new snap rings on the inner shaft.

11. Hold the outer shaft in a vise, and while keeping the snap ring (inner) compressed, install the inner shaft to the outer shaft.

After installing, verify that the inner shaft will not pull out.

ADJUSTMENT

Whenever the axle housing or the steering knuckle is replaced, the front driveshaft alignment and knuckle bearing preload are adjusted with SST. SST [09634-60013]

Plug

Rod

Attachment

Nut

1. Mount the SST on the housing SST [09634-60013]

Coat knuckle bearings lightly with molybdenum disulphide lithium base grease.

Add preload to the bearing by tightening the nut.

Preload (while turning): 1.8 - 3.8 kg (4.0 - 8.4 lb)

: Fig. 6-34

: Fig. 6-36

3. Measure the distance A

4. Measure the distance B.

5. The difference between A and B is the total adjusting shim thickness that is required to maintain the correct bearing preload.

6. Apply a light coat of red lead on the center part of rod (4).

7. Press the adapters (1) and (2) against the housing, press the plug (3) against the rod (5), and turn the lever (7) so as to have a line scribed on the rod (5).

8. Bolt on the knuckle spindle to the knuckle. - Note -

Install the bolt over two washers.

: Fig. 6-38

9. Dismount the SST from the housing, and mount it on the knuckle. SST [09634-60013]

1. Use care not to erase the scribed line when dismounting and remounting the SST.

2. Make sure that the rod (5) is in the same vertical direction that it was when mounted on the housing.

: Fig. 6-39

10. Turn the rod (5) and scribe another line on it.

11. Measure the distance D between the two scribed lines.

12. The thickness of the steering knuckle lower bearing shim E will be the distance D less 3 mm (0.12 in.).

LOWER SHIM THICKNESS E E = D - 3mm

13. The thickness of the steering knuckle^ upper bearing shim F will be differenc between the total adjusting shim thickness C and the shim thickness E.

Compare E and F with the thicknesses of the shims removed at disassembly. If there should be considerable difference, remeasure E and F.

Adjusting shim sizes

Part No.	Thickness mm (in.)
43236-60010	0.1 (0.004)
43233-60011	0.2 (0.008)
43234-60011	0.5 (0.020)

Install the oil seal with SST. Apply MP grease on the oil seal lip. SST [09618-60010] Place the oil seal set in the housing.

Apply molybdenum disulphide lithium base grease to the bearings, and install the knuckle and the bearings.

Hold the upper bearing inner race with SST. SST [09606-60020]

Install the knuckle arm over the shims that were originally used or were selected as described in adjustment operations

Use SST with a collar.

Install the lower bearing cap by the same procedure.

The SST should be removed before tightening the knuckle arm and the bearing cap. Tighten the knuckle arm and the bearing cap. Tightening torque: 8.5 -11.0 kg-m (62 - 79 ft-lb)

Measure the knuckle bearing preload. Preload (while rotating): 1.8 - 3.8 kg

0 Position one flat part of the outer shaft upward, and install the shaft. Pack molibdenum disulphide lithium base grease into the knuckle to about three fourth of the knuckle volume.
