Front wheel alignment (Steering)

FRONT WHEEL ALIGNMENT

Service Repair No. 57.65.01

Check

1. Ensure tyre pressures are correct, vehicle is at kerbside weight and on a level surface.
2. Release handbrake.
3. Roll vehicle backwards and forwards to relieve stresses in steering and front suspension.
4. Ensure that equipment is properly calibrated and take average of three readings.

Note: Use only equipment recommended in the S.T.E.P. (Service Tools and Equipment Programme) Manual.

5. Check that front wheel alignment is within tolerance:
   Front wheel alignment = toe – out 0° 10' ± 0° 15'

Adjust

1. Mark position of track rod for reference.

2. Slacken track rod lock nut.
3. Release clip securing gaiter to track rod.
4. Rotate track rod to obtain correct alignment.

CAUTION: Both track rods must be rotated an equal amount.

5. Roll vehicle backwards and forwards to relieve stresses in steering and front suspension.
6. Recheck front wheel alignment taking average of three readings.
7. Tighten track rod lock nut to 55 Nm.
8. Roll vehicle backwards and forwards to relieve stresses in steering and front suspension.
9. Repeat check procedure.
10. Repeat adjustment procedure if necessary.
11. Ensure gaiters are not strained or twisted, then tighten clip securing gaiter to track rod.

REAR WHEEL ALIGNMENT

Service Repair No. 57.65.06

Check

1. Ensure tyre pressures are correct and vehicle is at kerbside weight.
2. Ensure front wheel alignment is correct.
3. Release handbrake, position vehicle on level surface.
4. Roll vehicle backwards and forwards to relieve suspension.

Note: Use only equipment recommended in the S.T.E.P. (Service Tools and Equipment Programme) Manual.

5. Ensure that equipment to be used is properly calibrated and take average of three readings.
6. Check that alignment of each rear wheel is within tolerance:
   Rear wheel alignment = toe – in 0° 11' ± 0° 7½ ' per wheel.

Adjust

1. Mark position of adjusting bolt for reference.

2. Slacken adjusting bolt.
3. Using a piece of wood against arm forward of mounting, lever compensator arm inwards to increase and outwards to decrease toe – in.

Note: As an approximate guide, distance compensator arm is moved should be equal to amount wheel is out of alignment.

4. Tighten compensator arm adjusting bolt to retain adjustment.
5. Roll vehicle backwards and forwards to relieve suspension.
6. Recheck the alignment of wheels taking average of three readings.
7. When correct reading is achieved tighten compensator arm adjusting bolt to 45 Nm.
