Important Information for Working on Wheel Alignment of Vehicle

Conform with the following points when checking/adjusting wheel alignment.

Height Adjustment / Wheel Load Change

Changing the height on one side will simultaneously cause a change in wheel load. A wheel load change on one wheel will also change the wheel loads of the other wheels.

Wheel loads are increased by increasing the installed spring preload on one side (vehicle lifted).


Left rear spring preload C is increased. This causes the wheel load

- to increase at left rear C and right front B and

- to decrease at right rear D and left front A.

Wheel loads are reduced by reducing the installed spring preload on one side (vehicle lowered).

Wheel load changes are always transmitted diagonally to the other axle side. In other words, when the wheel load is reduced or increased on one wheel, the same thing happens on the diagonally opposite wheel.


The left to right wheel load difference should be as small as possible on the front and rear axles (less than 20 kg (44 lbs.) whenever possible).
