			The camber on the rear axle is not adjustable.
			If substantial deviations in the rear axle camber are found, the cause may be one of the following:
			* Too great a difference in vehicle level between right and left-hand sides of vehicle.
			* Accident damage on frame floor. Level differences at mounting points for rear axle carrier between left and right body side. Experience shows that bending caused by an accident also has an effect on the toe.

DIY toe-in measurement: Airmatic height setting

	Toe-in on a raised car ([[Airmatic]] level adjustment) can be 20' larger than on a lowered car. This should be taken into account when performing a toe-in adjustment.		==== Airmatic height setting ====
			Toe-in on a raised and lowered car ([[Airmatic]] level adjustment) can differ.
			On some cars we have observed that it differs just a little (around 5') while on other W220 vehicles toe-in on a raised car can be even 20' larger than on a lowered car.
			This should be taken into account when performing a toe-in adjustment.
			I.e., the toe-in should be adjusted for the Airmatic height setting that is usually used for driving.
			If both height settings are used equally, then the toe-in should be set to have the same distance from the targeted toe-in (0° 15') on a lowered and raised car.
