SUBJECT:Revised Conditions for Checking and Setting Wheel Alignment
Situation:In order to more accurately check and adjust wheel alignment, a revision has been made to the standard conditions required for a wheel alignment.
The revision is that the vehicle is loaded as described in the Technical Data, Page 32-100, and then the loading is adjusted, if necessary, to bring the vehicle height to specification. This eliminates any camber or toe variations due to ride height being different than design specification.
Procedure:Drive the vehicle onto the alignment rack, remove the lock pins from the turntables and slip plates, and load with weight bags as per Technical Data, Page 32-100. Measure the ride height from the bottom of the rim flange vertically to the bottom of the wheel opening. Check the ride height against the specification in the Technical Data, sections 31 and 33. If the ride height varies from the specification listed (disregard the tolerance), add or remove weight as necessary to bring the ride height to the listed specification. (Note: vehicles equipped with self-levelling suspension must have the levelling system powered up. Set rear ride height by adjusting self-levelling to proper specification.)
When the ride height has been adjusted to specification, check and adjust alignment as required.
For your convenience, attached is a chart showing weight requirements for normal loading and ride height specifications for all current models, as equipped when sold. For vehicles equipped with optional wheels, please refer to ride height specifications, sections 31 and 33 of Technical Data.
Note:Specifications are not available for vehicles equipped with non-approved or non-BMW wheels, or for vehicles with modified suspensions or body parts
