Incorrect height
sensor fitted voltages should be within ± 0.15v. To check sensor operation
on the vehicle: Check for water ingress around the height
sensors, electrical connectors or shaft end. Check for
excessive movement in the shaft in all directions. Raise
vehicle (ideally on wheels-free ramp) until suspension on
corner under investigation is at rebound to gain access to
height sensor. Access may be improved by removing road
wheel. Carefully disconnect the height sensor link from the
upper suspension arm. Monitor the height sensor signal
voltage output for the height sensor under investigation.
Position the sensor arm so it is in the mid position and
confirm that the voltage is around 2.5 volts. Move the sensor
arm over the range ±40° around the mid position and confirm
that the voltage changes smoothly between around 0.2 volts
and 4.8 volts. If voltages are incorrect or do not change
smoothly then replace sensor. NOTE: For angles of movement
beyond ±40°, the sensor signal will clamp to a voltage of
~0.15v or ~4.85v, depending on position of sensor lever. This
is normal. When investigation is complete, refit height sensor
link to upper arm. If any fixings to the height sensor body or
mounting bracket were slackened or found to be loose or if a
height sensor was changed, the vehicle ride height MUST be
re-calibrated. Refer to the relevant section of the workshop
manual for the calibration procedure C1A05-22

re-calibrated. Confirm that the correct height sensor part
number is fitted, as specified in the service parts database.
To check height sensor: Disconnect electrical connector to
height sensor and inspect connecter pins & terminals for
evidence of corrosion or water ingress. If no corrosion found,
disconnect harness at Control Module. A: Check for short
circuits between any of the 3 terminals and vehicle ground. B:
Check for electrical continuity between the two connectors for
each of the 3 terminals. Reconnect electrical connector at
Control Module only. C: Check voltages at terminals within
height sensor connector (sensor not connected), with respect
to vehicle body. • Voltage to sensor ground connection should
be ~0v • Voltage to sensor signal connection should be ~0v •
Voltage to sensor supply connection should be ~5v All
voltages should be within ± 0.15v. To check sensor operation
on the vehicle: Check for water ingress around the height
sensors, electrical connectors or shaft end. Check for
excessive movement in the shaft in all directions. Raise
vehicle (ideally on wheels-free ramp) until suspension on

Noise Conditions

Gear noise is typically a howling or whining due to gear damage or incorrect bearing preload. It can occur at various
speeds and driving conditions, or it can be continuous
Chuckle is a particular rattling noise that sounds like a stick against the spokes of a spinning bicycle wheel. It occurs
while decelerating from approximately 64 km/h (40 miles/h) and can usually be heard all the way to a stop. The
frequency varies with vehicle speed
Knock is very similar to chuckle, though it may be louder and occurs on acceleration or deceleration. The tear down will
disclose what has to be corrected
Check and rule out tires, exhaust and trim items before disassembling the transmission to diagnose and correct gear noise.

The noises described under Road Test usually have specific causes that can be diagnosed by observation as the unit is
disassembled. The initial clues are the type of noise heard on the road test and the driving conditions.

Vibration Conditions


wear. NOTE: New Constant Velocity (CV) joints should not be installed unless disassembly and inspection revealed unusual

Clicking, popping or grinding noises may be caused by the following:

Cut or damaged CV joint boots resulting in inadequate or contaminated lubricant in the outboard or inboard CV joint
bearing housings
Loose CV joint boot clamps
Another component contacting the rear drive half shaft
Worn, damaged or incorrectly installed wheel bearing, suspension or brake component
Vibration at highway speeds may be caused by the following:
Out-of-balance front or rear wheels
Out-of-round tires
Driveline imbalance
Driveline run-out (alignment)


NOTE: Rear drive half shafts are not balanced and are not likely to contribute to rotational vibration disturbance.
Shudder or vibration during acceleration (including from rest) may be caused by the following:
Driveline alignment
Excessively worn or damaged outboard or inboard CV joint bearing housing
Excessively high CV joint operating angles caused by incorrect ride height. Check ride height, verify correct spring rate
and check items under Inoperative Conditions
Excessively worn driveshaft components

Leakage Conditions

1. Inspect the CV joint boots for evidence of cracks, tears or splits.

2. Inspect the underbody for any indication of grease splatter in the vicinity of the rear drive half shaft, outboard and
inboard CV joint boot locations, which is an indication of CV joint boot or CV joint boot clamp damage.
3. Inspect the inboard CV joint bearing housing seal for leakage.

Inoperative Conditions

If a CV joint or rear drive half shaft pull-out occurs, check the following:

suspension components for correct location, damage or wear
bushings for wear
subframe for damage
bent or worn components
- Stabilizer bar link
- Left-hand rear suspension lower arm and bushing
- Right-hand rear suspension lower arm and bushing
- Rear wheel hub and rear drive half shaft

Road Test

A gear-driven unit will produce a certain amount of noise. Some noise is acceptable and may be audible at certain speeds or
under various driving conditions as on a newly paved blacktop road. The slight noise is in no way detrimental and must be
considered normal.

The road test and customer interview (if available) provide information needed to identify the condition and give direction to
the correct starting point for diagnosis.
1. Make notes throughout the diagnosis routine. Make sure to write down even the smallest piece of information, because
