GUIDE

Driveshaft Components

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.

Failure Analysis

Component failures can result from improper

maintenance, installation or assembly procedures.

This quick reference guide assists service

technicians in recognizing component failures and

identifying probable causes.

Rotating shafts can be dangerous.

You can snag clothes, skin, hair, hands, etc.

This can cause serious injury or death.

Do not go under the vehicle when the

engine is running.
