Check

1

Observe general information on chassis alignment.

AR40.20-D-0201H

 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-6870H

2.2

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

When measuring without electronic inclinometer.

 Commercially available devices/tools
Wheel load scales

3

Swivel sun visor to one side and fix steering wheel in center position.

 Retainer device

*129589012100

 Tensioning nut

*906589002100

4

Check center position of steering wheel and steering gear.

 The steering gear is at the center position when the marking on the cap is aligned with the marking on the control valve housing.

If the center position is incorrect,



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

AR46.10-D-0100E

5

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.

6

Perform initial measurement.

AR40.20-D-0200H

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

7

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 values for major wear on the tire outer shoulder must be used.

Adjust

8

Adjust toe to determined specified value.

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

Note on calculation of tightening torque when using insertion or socket tools with various effective lengths

AH00.00-P-0015-01CW

 To do so, release counter nuts (10 f), adjust toe by turning the tie rods (10) then tighten counter nuts (10 f) again. Counterhold ball heads of tie rods (10) while doing so.

 Lock nut at ball head
