PROPELLER SHAFT VIBRATION
If vibration is present at high speed, inspect propeller shaft runout
®rst.
1. Raise front and rear wheels.
2. Measure propeller shaft runout at several points by rotating
®nal drive companion ¯ange with hands.
Runout limit: 0.6 mm (0.024 in)
3. If runout exceeds speci®cations, disconnect propeller shaft at
®nal drive companion ¯ange; then rotate companion ¯ange 180
degrees and reconnect propeller shaft.
4. Check runout again. If runout still exceeds speci®cations,
replace propeller shaft assembly.
5. Perform road tests.
APPEARANCE CHECKING
+Inspect propeller shaft tube surface for dents or cracks. If
damaged, replace propeller shaft assembly.

Removal
+Remove propeller shaft.
+Remove drive shaft. Refer to FA section (``FRONT AXLE Ð
Knuckle Flange'').
+Remove axle shaft.
Refer to RA section (``REAR AXLE'').
+Remove front and rear ®nal drive mounting bolts.
CAUTION:
+Be careful not to damage spline, sleeve yoke and front oil
seal when removing propeller shaft.
+Before removing the ®nal drive assembly or rear axle
assembly, disconnect the ABS sensor harness connector
from the assembly and move it away from the ®nal drive/
rear axle assembly area. Failure to do so may result in the
sensor wires being damaged and the sensor becoming
inoperative.
Installation
+Fill ®nal drive with recommended gear oil.
+Pay attention to the direction of gasket.
