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 (1) and cross and bearing
assemblies may cause an excessive amount of vibration
or noise.
Individually inspect each cross (2) the needle bearings
and cap (4) for signs of wear or for 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: Yoke flange (3) is used on the engine-to-
transmission drive shaft assembly only.
1. Replace the felt seal (9) if worn or damaged.
2. Replace the entire drive shaft assembly if any flange
yoke, slip yoke or drive shaft tube is severely dented
or damaged.
3. 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.
