Trim Height Inspection

Incorrect trim height can cause bottoming out over bumps. Incorrect trim height can cause possible damage to the suspension components and symptoms similar to those produced when there is a problem with the wheel alignment. Measure the trim height when diagnosing suspension complaints and before checking the wheel alignment.
Perform the following before measuring the trim height:
1. Set the tire pressures to the pressure shown on the tire placard. The tire placard is located on the driver's door lock pillar.
2. Ensure the tires match the tire size specifications shown on the tire placard.
3. Ensure the wheels match the wheel size specifications shown on the tire placard.
4. Ensure that the fuel tank is full or add additional weight in order to simulate a full tank.
5. Place the front seats in the full rearward position.
6. Ensure the rear compartment is empty except for the jack and the simulated fuel load.
7. Ensure the spare tire is installed on the spare tire carrier.
8. Ensure the vehicle is on a level surface, such as an alignment rack.
9. Close the hood.
10. Close the doors.
11. Close the rear door or the end gate.

Important: All dimensions are measured vertical to the ground. A trim height measurement within 10 mm (0.4 inch is considered correct.
