On-vehicle Service
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.
