Trim height is a predetermined measurement relating to vehicle ride height. Incorrect trim heights can cause bottoming 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:

Make sure the vehicle is on a level surface, such as an alignment rack.
Remove the alignment rack floating pins.
Set the tire pressures to the pressure shown on the certification label.
Check the fuel level. Add additional weight if necessary to simulate a full tank.
To ensure proper weight distribution make sure the rear storage compartment is empty.
Close the doors and hood.
