PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft
runout first.
1. Raise rear end of vehicle until wheels are clear of the ground.
2. Measure propeller shaft runout at several points along pro-
peller shaft by rotating final drive companion flange using
hands.
3. If runout exceeds specifications, disconnect propeller shaft at
final drive companion flange. Rotate companion flange 180
degrees, then reconnect propeller shaft.
Runout limit: 0.6 mm (0.024 in)
4. Check runout again. If runout still exceeds the limit, replace
propeller shaft assembly.
5. Perform road test.
APPEARANCE CHECKING
lInspect propeller shaft tube surface for dents or cracks and
replace as necessary.
lCheck center bearing for noise or damage and replace as
necessary.
Removal and Installation
1. Place matching marks on flanges, then separate propeller
shaft from final drive.
2. Remove propeller shaft.
lInsert plug into rear oil seal after removing rear propel-
ler shaft.
Inspection
lInspect propeller shaft runout. If runout exceeds the limit,
replace propeller shaft assembly.
Runout limit: 0.6 mm (0.024 in)

Tooth Contact
Gear tooth contact pattern check is necessary to verify correct
relationship between ring gear and drive pinion.
Hypoid gear sets which are not positioned properly may be
noisy, or have short life, or both. With a pattern check, the most
desirable contact for low noise level and long life can be assured.
1. Thoroughly clean ring gear and drive pinion teeth.
2. Sparingly apply a mixture of powdered ferric oxide and oil or
equivalent to 3 or 4 teeth of ring gear drive side.
3. Hold companion flange steady and rotate the ring gear in
both directions.

Extension Tube and Differential Side Shaft
1. Measure rear axle bearing end play.
Rear axle bearing end play (A þ B):
0.1 mm (0.004 in) or less
The end play can be adjusted with bearing adjusting shim.
Available bearing adjusting shims:
Refer to SDS, PD-78.
2. Install grease seal.
3. Install extension tube retainer, rear axle bearing and rear
axle shaft bearing collar on differential side shaft.
4. Install differential side shaft assembly into extension tube.
Differential Case
1. Measure clearance between side gear thrust washer and
differential case.
Clearance between side gear thrust washer
and differential case (A þ B):
Less than 0.15 mm (0.0059 in)
The clearance can be adjusted with side gear thrust washer.
Available side gear thrust washers:
Refer to SDS, PD-78.
2. Apply gear oil to gear tooth surfaces and thrust surfaces and
check to see they turn properly.
