3.

From the small circle between the wheels 

(on the vehicle centreline), draw a straight 

line to the test reading scales at the side of 

the wheel. This should be done for both 

wheels (drawing 3).

The axle (mis)alignment relative to the 

vehicle centreline is now visible.

4.

To realign the axle in this example, it would 

have to be rotated 3 mm/m to the right 

(drawing 4).

Example 2
1.

Mark the test readings in the scales at the top 

and side of the measured wheel. In the 

example (drawing 5) the misalignment has 

been determined as a 3 mm/m toe-in in 

relation to the vehicle centreline for the left 

wheel and a 1 mm/m toe-out in relation to the 

vehicle centreline for the right wheel.

2.

From the small circle at the bottom of the 

wheel, draw a straight line to the test reading 

indicated on the wheel top scale. This should 

be done for both wheels (drawing 6).

The (mis)alignment of the wheels relative to 

the vehicle centreline is now visible.

3.

From the small circle between the wheels 

(on the vehicle centreline), draw a straight 

line to the test reading scales at the side of 

the wheel. This should be done for both 

wheels (drawing 7). The axle (mis)alignment 

relative to the vehicle centreline is now 

visible. From the figure it becomes apparent 

that this axle is not entirely straight. The 

wheels of this axle have a 2 mm/m toe-in 

relative to one another.

4.

Divide the total toe-in equally over the two 

wheels. The toe-in per wheel would be 1 mm/

m. Mark these values on the top scales 

(drawing 8).

5.

From the small circle at the bottom of the 

wheels, draw straight dotted lines to the 1 

mm/m markings on the scales (drawing 8).

6.

From the small circle between the wheels 

draw a straight dotted line to the 1 mm/m 

marking on the scale at the side of the wheel. 

This should be done for both wheels 

(drawing 9).

The ideal position of the axle is now made 

visible by the dotted lines (drawing 9).

7.

To realign the axle in this example, it would 

have to be rotated 2 mm/m to the left 

(drawing 10).

Example 3
This example refers to a vehicle with two rear 

axles.

1.

The adjacent drawing shows the axles of the 

previous two examples. The positions of the 

two axles relative to the vehicle centreline 

have already been determined.

2.

The necessary realignment value (in mm/m) 

for the two axles is also the misalignment 

value relative to the vehicle centreline.

Enter these values in the scale of the figure 

at the bottom of drawing 11. Take care to 

enter this value on the correct side (+ or - 

side) of the vehicle centreline indicated in 

this drawing.

3.

From the small circles in the centre of the left 

wheels, draw straight lines to the markings 

on the scale (drawing 12). The position of the 

two axles relative to each other is now 

visible. With this, it can be determined 

whether the axles need realigning, and 

which one needs realigning.

Any adjustment necessary can also be 

indicated as a dotted line in the figure.

Note:

Quite often, it is only necessary to realign 

one of the axles to get both axles positioned 

parallel to each other (within the permitted 

tolerance limits).

4.

The non-parallelism in this example is 5 mm/

m. In this case, it is therefore sufficient to 

reposition only the front axle.

Note:

The method of repositioning the axle 

depends on the type of axle suspension.
