 Determine difference between the inner and outer tire tread channel depth here too.

2.1

Determine front-axle level using the transverse control arm angle bracket with electronic inclinometer.

When measuring with electronic inclinometer.

AR40.20-D-6870TS

2.2

Determine front-axle level through actual front-axle load.

When measuring without electronic inclinometer.

If the center position is incorrect,



remove steering wheel, shift by max. one tooth then mount steering wheel again.

Remove/install steering wheel

AR46.10-D-0100TS

4

Install wheel spreader (030), as shown, in direction of travel at front on insides of wheel.

 The elastic bearing of the lower transverse control arm and steering linkage produce a correspondingly large toe value that is reduced to the correct dimension in the ready-to-drive condition.

5

Perform initial measurement.

AR40.20-D-0200TS

 The actual suspension data such as camber, toe, steering axis inclination, caster and the toe-out angle are determined here.

6

Check toe using front-axle level and assign to value in table.

 Observe permissible difference in front axle toe-in between right and left sides of the vehicle.

 If the determined difference between the inner and outer tread groove depth is greater than 2 mm, then the values for major wear on the tire outer shoulder must be used.

7

Adjust toe to determined specified value.

If the actual values deviate from the specified values or if the tire outer shoulder exhibits wear.
