CHECKING OPERATIONS

Rear Axle Alignment, Check

Camber and Toe-in, Check

The following conditions must be fulfilled to ensure accurate measurement of alignment:

1.  Tread on all tyres uniform and in good condition.

2.  Tyre pressures must be equal on both sides of the axle - see "Technical Data", group E for values for maximum loading.

3.  The rim of each disc wheel to be checked must be in satisfactory condition.

4.  Prepare vehicle for measurement: Load each of the front seats with 70 kg/154 lbs. Fuel tank half full. Stabilize the springs by rocking the vehicle several times (even if the vehicle was previously raised). If this measure is omitted, the camber angle measured will be too great, as the rear axle will not have assumed its normal neutral position.

Note:

When using axle alignment turntables which cannot record lateral forces, the vehicle must initially be rolled back about 1 m/1 yd. and then pushed forward again.

Establish "actual values" using optical axle alignment tester and complete alignment measurement card.

Required camber and toe-in values (not adjustable) for checking operations are:

Drum Brake                           Disc Brake

Camber:                                  -0°  30'                                             -1°  40'

Tolerance range:                    -1° to 0°                                            -2°  10' to -1°  10'

(Variation from left to right wheel max.  0°  30')

Toe-in:                                     10'  Toe-out to 40'  Toe-in               -1 to +4 mm/-0.04 to +0.16 in.

(applies to both wheels)         (Variation from left to right wheel max.  0°  15')

Correction is not possible. If there are deviations, the rear axle assembly or the wheel spindle are to be checked for any possible damage.
