and drive half shaft failure, which could cause serious personal injury and extensive vehicle damage. Failure to follow these
instructions may result in personal injury.


CAUTION: The suspension should not be allowed to hang free. When the CV joint is run at a very high angle, extra
vibration as well as damage to the seals and joints can occur.

The rear suspension lower arm should be supported as far outboard as possible. To bring the vehicle to its correct ride height,
the full weight of the vehicle should be supported in the rear by floor jacks. REFER to: (100-02 Jacking and Lifting)

Jacking (Description and Operation), Lifting (Description and Operation).
1. Raise and support the vehicle. REFER to: (100-02 Jacking and Lifting)
Jacking (Description and Operation), Lifting (Description and Operation).
2. Explore the speed range of interest using the Road Test Quick Checks as previously described.

3. Carry out a coast down in neutral. If the vehicle is free of vibration when operating at a steady indicated speed and
behaves very differently in drive and coast, a transmission concern is likely.

Note, however, that a test on the lift may produce different vibrations and noises than a road test because of the effect of the
lift. It is not unusual to find vibrations on the lift that were not found in the road test. If the condition found on the road can
be duplicated on the lift, carrying out experiments on the lift may save a great deal of time.

Exhaust Neutralization Procedure

1. Raise vehicle on lift and slacken all exhaust fixings.

2. With all fixings loose, neutralize the exhaust system.

3. Tighten all fixings to correct torque, starting at the rear-most point working towards the front of the vehicle.

NOTE: These Pinpoint Tests are designed to take the technician through a step-by-step diagnosis procedure to determine
the cause of a condition. It may not always be necessary to follow the chart to its conclusion. Carry out only the Pinpoint Test
steps necessary to correct the condition. Then check operation of the system to make sure the condition is corrected.
After verifying that the condition has been corrected, make sure all components removed have been installed.

General Procedures
NOTES:

The camber and caster adjustment for the left-hand side is shown, the procedure for adjusting the right-hand side is
similar.


This procedure must be carried out using a 4-post ramp.


Adjustments to the camber will affect the toe settings. Therefore, the camber and toe may need to be adjusted at the
same time to achieve the correct settings.


Adjustments to the camber may affect the caster settings. Therefore, the caster will need to be checked, and adjusted as
necessary.
