Inspection
Bearing Plate (Full Round) Yoke Inspection
Please refer to the End Fitting information in the Component
Safety section on page 2.
1. Refer to original-equipment manufacturer for
removal of the driveshaft from the vehicle.
2. Place the driveshaft in v-blocks to remove the cross
and bearing assemblies. Completely remove the
cross and bearings from the yokes at both ends of
the driveshaft using a universal joint removal tool.
Next, disassemble the bearing assemblies from the
slip yoke (and flange yoke, where applicable), using
a tool kit.
3. Clean the cross holes on the yoke, and inspect the
cross hole surfaces for damage or raised metal.
Raised metal or fretting can be removed from yoke
cross holes with a fine-toothed file and/or emery
cloth.
DO NOT deform yoke cross holes by removing excessive
metal. Raised metal or deformed yoke cross holes can
cause cross and bearing failure, which can result in separa-
tion of the driveline from the vehicle.
4. Check the yoke lug cross holes with a No-Go Wear
Gauge, and then use a Spicer Alignment Bar to
inspect for damage by sliding through both cross
holes simultaneously.
The alignment bar will identify yoke lugs that have
taken a set because of excessive torque. The raised
metal or distorted lugs can be a cause of premature
cross and bearing problems.
5. If, after proper cleaning of the cross holes, the align-
ment bar will not pass through both cross holes
simultaneously, the yoke lugs are distorted, and the
yoke or yokes should be replaced.
