5.4.1 Drive Shaft Inspection and Service

Whenever servicing the vehicle, conduct a visual

inspection of the drive shafts, and cross and bearing

assemblies (universal joints, or U-joints). A few moments

spent doing this can help prevent further problems and

down time later.

Inspect areas where the drive shaft flange yokes and slip

yokes mount to the drive shafts. Attempt to turn each

drive shaft in both directions. Look for excessive

looseness, missing parts, cracks or other damage. Worn

or damaged drive shafts (Fig. 5-8) and cross and bearing

assemblies may cause an excessive amount of vibration

or noise.

1. Individually inspect each cross (Fig. 5-8, 2) the

needle bearings and cap (4) for signs of wear or

missing parts.

Note: Replace the cross and bearings as a complete

assembly if any parts are worn or missing. If all parts of

the cross and bearing assemblies are in good condition,

pack the bearing caps with a premium grade of multi-

purpose wheel-bearing grease. Reattach the bearing

cap to the cross, assuring that all needle bearings are

present. Then, reassemble the cross and bearing

assembly into the drive shaft yoke.

Note: The yoke flange (Fig. 5-8, 3) is used on the

engine-to-transmission drive shaft assembly only.

2. Replace the felt seal (Fig. 5-8, 8) if worn or

damaged.

3. Replace the entire drive shaft assembly if any flange

yoke, slip yoke or drive shaft tube is severely dented

or damaged.

4. Cross assemblies should flex and be free from

excessive binding. A slight amount of drag or

resistance is desirable on a new cross and bearing

assembly. Excessive looseness causes unbalance.
