Driveshaft Diagnosis; Noise And/Or Vibration In Turns; Clunking Noise During Acceleration; Shudder Or Vibration During Acceleration - Chrysler 2000 LHS Owner's Manual

3 - 4 DIFFERENTIAL AND DRIVELINE
DESCRIPTION AND OPERATION (Continued)
OPERATION
Driveshaft assemblies are designed to transmit
power from the transaxle to the front wheels, while
allowing for powertrain and suspension flex.
DIAGNOSIS AND TESTING

DRIVESHAFT DIAGNOSIS

VEHICLE INSPECTION
(1) Check for grease in the vicinity of the inboard
tripod joint and outboard C/V joint; this is a sign of
inner or outer joint seal boot or seal boot clamp dam-
age.
(2) A light film of grease may appear on the inner
tripod joint seal boot; this is considered normal and
should not require replacement of the seal boot. All
inner tripod joint seal boots are made of silicone rub-
ber; which will allow the weeping (sweating) of the
joint lubricant to pass through it while in operation.

NOISE AND/OR VIBRATION IN TURNS

A clicking noise and/or a vibration in turns could
be caused by one of the following conditions:
(1) Damaged outer C/V 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.
(2) Noise may also be caused by another compo-
nent of the vehicle coming in contact with the drive-
shafts.

CLUNKING NOISE DURING ACCELERATION

This noise may be a result of one of the following
conditions:
(1) A torn seal boot on the inner or outer joint of
the driveshaft assembly.
(2) A loose or missing clamp on the inner or outer
joint of the driveshaft assembly.
(3) A damaged or worn driveshaft C/V joint.

SHUDDER OR VIBRATION DURING ACCELERATION

This problem could be a result of:
(1) A worn or damaged driveshaft inner tripod
joint.
(2) A sticking tripod joint spider assembly (inner
tripod joint only).
(3) Improper wheel alignment. See Wheel Align-
ment in this group for alignment checking and set-
ting procedures and specifications.
VIBRATION AT HIGHWAY SPEEDS
This problem could be a result of:
(1) Foreign material (mud, etc.) packed on the
backside of the wheel(s).
(2) Out of balance front tires or wheels. See Group
22, Wheels And Tires for the required balancing pro-
cedure.
(3) Improper tire and/or wheel runout. See Group
22, Wheels And Tires for the required runout check-
ing procedure.
REMOVAL AND INSTALLATION
FRONT DRIVESHAFTS
NOTE: The only service which is to be performed
on the driveshaft assemblies is the replacement of
the driveshaft seal boots or replacement of the
entire assembly.
If any failure of internal driveshaft components is
diagnosed during a vehicle road test or disassembly
of the driveshaft, the driveshaft assembly will need
to be replaced.
REMOVAL
(1) Raise vehicle on jackstands or centered on a
frame contact type hoist. Refer to Hoisting, in the
Lubrication and Maintenance section of this manual,
for the required lifting procedure to be used for this
vehicle.
(2) Remove the front wheel and tire assembly from
the vehicle.
(3) Remove the front caliper assembly from the
front steering knuckle assembly (Fig. 3). Refer to
Front Disc Brake Service in the Brake Section of this
service manual for caliper removal procedure.
