Preventive Maintenance
Driveshaft inspection should be performed as part
of a regular maintenance routine. Normal vehicle
maintenance and recognition of component
discrepancies is necessary to prevent serious
mechanical problems as well as driver discomfort.
Failure to perform normal maintenance may also
void the vehicle warranty.
Routine Inspection Steps
1. Check the output and input end yokes for
looseness.
2. Check for excessive radial looseness of output/
input shaft.
3. Check for looseness across ends of u-joint.
4. Check the slip spline for excessive radial
movement.
5. Check the shaft for damage, bent tubing or
missing balance weights.
6. Check for loose or missing plug.
