Vehicle trim height, "Zero position"
In general!
If a value lies outside the tolerance, the vehicle's trim height must be checked first.
If the measured values are outside the allowed tolerances, the cause may be an incorrect vehicle attitude.
Right-hand drive vehicles or for example vehicles with automatic transmission can lean to one side slightly.
This is due to the installation position of components and weight distribution
- It is absolutely necessary to measure dimension "a" on left and right hand sides.
The O line on the roof means the horizontal position (zero position) of the vehicle.
- Correct differences if necessary.
It is possible to correct trim height imbalance for front axle by adding weight to top of strut tower and/or adding weight in trunk for rear axle, example: sand bags can be used, approx. 10 kg (22 lbs.)
