Inspection Procedures
4. Apply effort perpendicular to shaft axis making note
of total indicator travel. Allowable indicator travel is
.000-.012 in.
Excessive radial looseness can cause imbalance or vibra-
tion in the driveshaft assembly. Imbalance or vibration can
cause component wear, which can result in separation of
the driveline from the vehicle.
5. For an inboard and outboard slip yoke assembly
design, check to be sure the slip yoke welch plug is
not loose, missing or damaged.
If any of these situations are evident, replacement of
the slip yoke and professional rebalancing of the
driveshaft is necessary.
6. Visually inspect for the presence of the grease zerk
fitting, if applicable, on the slip yoke.
a. If grease zerk fitting is loose, tighten to required
specifications. (See Table C.)
b. If grease zerk fitting is missing or fractured, the
slip members may need to be replaced.
7. Check the slip yoke seal. Make sure the seal is prop-
erly attached to the slip yoke and is not loose or
damaged.
Permanently Lubricated Style
Check the yoke shaft boot. Make sure the boot is properly
attached to the yoke shaft assembly and splined sleeve. Visu-
ally inspect for boot tears, punctures, loose clamps and clamp
damage.
If any of these situations are evident, replace damaged com-
ponents and measure slip joint movement.
