GENERAL DESCRIPTION
One type of propeller shaft is being used in 1977. The
type being used on all series is a one-piece shaft with two
single cardan universal joints.
A universal joint and splined slip yoke are located at the
transmission end of the shaft, where they are held in
alignment by a bushing in the transmission rear extension.
The slip yoke permits fore and aft movement of the drive
shaft, as the differential assembly moves up and down. The
spline is lubricated internally by transmission lubricant. An
oil seal at the transmission prevents leakage and protects the
slip yoke from dust, dirt, and other harmful material.
The universal joints are lubricated for life and cannot be
lubricated while on the car. A service kit, which consists of
a spider with bearing assemblies and snap rings, must be
installed on the car if a universal joint becomes worn or noisy.
If it becomes necessary to repair a universal joint, the entire
propeller shaft must be removed from the car. Care should
be taken to avoid jamming, bending, or over-angulating of
any parts of the assembly.
If a car is to be undercoated, the propeller shaft must
be
kept
completely
free of
undercoating
material.
Undercoating material or any other foreign material will
upset the propeller shaft balance and produce serious
vibration.
On all series cars, except
H
and
X,
production universal
joint bearing are retained by a nylon injection ring instead of
the conventional snap ring. The
H
and
X
Series cars use the
snap rings. All service universal joints, however, will use snap
I
rings.
