Front

Front Wheel Alignment: Checking / Adjusting

NOTE: All measurements are made with the car empty. Check and adjust the air pressure all round, if necessary.

1. Camber And Caster readings must be checked first, then the toe-in should be checked and adjusted if needed.




2. Lift up front end.
- Lift under control arms as close to the ball joints as possible.
3. Check play in the front suspension if necessary.
- Check for play in:
- Steering gear or tie rods
- Wheel bearings
- Upper shock absorber bearings
- Control arm ball joints and bushings
- If there is play in any of the above components it must be corrected.




4. Position turntables under the front wheels.
- Use the turntables to take up lateral movement.
- The car must stand level when the front wheels are on turntables.
- So that the correct values are obtained when checking camber and caster.




5. Lower suspension.
- Bounce the front suspension heavily a few times when the car has sunk onto the turntables.
- This must be done for the front suspension to resume the normal position.




6. Set up test equipment.
- Set up and calibrate the test equipment according to the equipment manufacturers instructions.

Checking Camber Angle 960 1995 On
- Check camber angle with test equipment in the usual way.




- Correct camber angle: To determine the correct camber angle the car height must be taken into account.
- This is carried out as follows: Measure the fender edge measurement on both sides of the car (`'A" = steel rim, "B" = aluminium rim).



- Reading off the chart.
- Read off the chart.
- With the help of the fender edge measurement and rim curve the camber angle degree required can be read off.
- Rim curves according to the chart
A = 15" aluminum rim
B = 15" steel rim
C = 16" aluminum rim
D = 17" aluminum rim
A tolerance of +0.5° is allowed.

NOTE:
The Caster Angle Cannot Be Adjusted From The 1995 Model Year Onwards. The Control Arm And The Control Arm Strut Have Been Replaced By A Cast Control Arm.




- If the value is +3°, it means that the bearing is the wrong way round. Remove the lock nuts and turn the bearing. After adjusting caster angle adjust toe-in to within specified values.

Toe-in Adjustments

Checking Toe-in On Cars With Multilink Suspension

- Check that the instruments are adjusted in relation to each other on the front and rear axles. It is important to be able to adjust front wheel toe-in in relation to the car's thrust line. Thrust line is the line created when the rear wheels toe-in angles are equally divided as shown in the illustration.





NOTE:
The difference between the wheel symmetry line and the thrust line is called the thrust angle. The maximum allowed variation from the symmetry line according to Multilink specifications: 8'(0.25°).




- Adjustment is by the tie rods after loosening the locknuts. Shorter struts give greater angles and vice versa. Correct value: Nominal: 18' ± 8'
