HALF SHAFT - REAR
DESCRIPTION
The inner and outer joints of both half shaft
assemblies are tripod joints. The tripod joints are
true constant velocity (CV) joint assemblies, which
allow for the changes in half shaft length through
the jounce and rebound travel of the rear suspension.
On vehicles equipped with ABS brakes, the outer
CV joint is equipped with a tone wheel used to deter-
mine vehicle speed for ABS brake operation.
The inner tripod joint of both half shafts is bolted
rear differential assembly's output flanges. The outer
CV joint has a stub shaft that is splined into the
wheel hub and retained by a steel hub nut.
DIAGNOSIS AND TESTING - HALF SHAFT
VEHICLE INSPECTION
(1) Check for grease in the vicinity of the inboard
tripod joint and outboard CV joint; this is a sign of
inner or outer joint seal boot or seal boot clamp dam-
age.
NOISE AND/OR VIBRATION IN TURNS
A clicking noise and/or a vibration in turns could
be caused by one of the following conditions:
²Damaged outer CV or inner tripod joint seal
boot or seal boot clamps. This will result in the loss
and/or contamination of the joint grease, resulting in
inadequate lubrication of the joint.
²Noise may also be caused by another component
of the vehicle coming in contact with the half shafts.
CLUNKING NOISE DURING ACCELERATION
This noise may be a result of one of the following
conditions:
²A torn seal boot on the inner or outer joint of the
half shaft assembly.
²A loose or missing clamp on the inner or outer
joint of the half shaft assembly.
²A damaged or worn half shaft CV joint.
SHUDDER OR VIBRATION DURING ACCELERATION
This problem could be a result of:
²A worn or damaged half shaft inner tripod joint.
²A sticking tripod joint spider assembly (inner tri-
pod joint only).
²Improper wheel alignment. (Refer to 2 - SUS-
PENSION/WHEEL ALIGNMENT - STANDARD
PROCEDURE)
VIBRATION AT HIGHWAY SPEEDS
This problem could be a result of:
²Foreign material (mud, etc.) packed on the back-
side of the wheel(s).
²Out of balance tires or wheels. (Refer to 22 -
TIRES/WHEELS - STANDARD PROCEDURE)
²Improper tire and/or wheel runout. (Refer to 22 -
TIRES/WHEELS - DIAGNOSIS AND TESTING)

necting shaft (Fig. 15).
(5) Install the snap-ring to hold the tripod assem-
bly onto the interconnecting shaft (Fig. 16).
(6) Install the new large diameter retaining clamp
onto the CV joint housing.
(7) Distribute 1/2 the amount of grease provided in
the seal boot service package (DO NOT USE ANY
OTHER TYPE OF GREASE) into tripod housing. Put
the remaining amount into the sealing boot.
(8) Install the CV housing onto the interconnecting
shaft and tripod assembly (Fig. 17).
(9) Clamp the half shaft into a suitable vise with
protective jaws clamped onto the interconnecting
shaft.
(10) Position the CV joint boot on interconnecting
shaft so the raised bead on the inside of the small
diameter end of the seal boot is in mating groove on
interconnecting shaft (Fig. 18).

SPECIAL TOOLS
BASE BRAKE SYSTEM
BRAKE FLUID LEVEL SWITCH
DESCRIPTION
The brake fluid level switch is located in the brake
fluid reservoir of the master cylinder (Fig. 4).
OPERATION
The purpose of the brake fluid level switch is to
provide the driver with an early warning that the
brake fluid level in the master cylinder fluid reser-
voir has dropped below a normal level. This may
indicate:
²Abnormal loss of brake fluid in the master cyl-
inder fluid reservoir resulting from a leak in the
hydraulic system.
²Brake shoe linings which have worn to a point
requiring replacement.
As the brake fluid drops below the minimum level,
the brake fluid level switch closes to complete the red
BRAKE warning indicator (lamp) circuit. This will
turn on the red BRAKE warning indicator. The mas-
ter cylinder fluid reservoir should be checked and
refilled to the Full mark with DOT 3 brake fluid.If
the brake fluid level has dropped below the add
