Trim Height Inspection Procedure
Trim Height Measurement
Trim height is a predetermined measurement relating to vehicle ride height. Incorrect trim heights can cause the vehicle to bottom out over bumps,
damage to the suspension components and symptoms similar to wheel alignment problems. Check the trim heights when diagnosing suspension concerns
and before checking the wheel alignment.
Perform the following before measuring the trim heights:
^
Set the tire pressure to the specifications shown on the certification label. Refer to Label - Vehicle Certification, Tire Place Card, Anti-Theft and
Service Parts ID in General Information.
^
Check the fuel level. Add additional weight if necessary to simulate a full tank.
^
Make sure the passenger and rear compartments are empty, except for the spare tire.
^
Make sure the vehicle is on a flat and level surface, such as an alignment rack.
^
Check that all the vehicle doors are securely closed.
^
Check that the vehicle hood and rear deck lids are securely closed.
^
Check for installed after market accessories or modifications that could affect trim height measurement.
Important:
All dimensions are measured vertical to the ground. Trim height should be within +/- 10 mm (+/-0.39) to be considered correct.
