Trim Height Inspection
Trim Height Measurements
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:
1. Set the tire pressures to the pressure shown on the certification label and/or in the Owners Manual.
2. Check the fuel level. Add additional weight if necessary to simulate a full tank.
3. Make sure the rear compartment is empty except for the spare tire.
4. Make sure the vehicle is on a level surface, such as an alignment rack.
5. Close the doors.
6. Close the hood.
7. All dimensions are measured vertical to the ground. Trim heights should be within -10 mm to +10 mm to be considered correct.
Measuring the P and R Dimension
Measuring the P and R Dimension
Use the following procedure to check the P and R dimensions:
1. Use your hands to lift the front bumper approximately 38 mm (1.59 in).
2. Remove your hands and allow the vehicle to lower.
3. Use your hands to jounce the front of the vehicle downward approximately 38 mm (1.59 in).
4. Remove your hands and allow the vehicle to rise.
5. The dimension P for the left and right side of the vehicle is measured from the bottom lip of the wheel opening to the ground measured at the
center line of the front wheel.
6. Compare the measurement to the specification table. Refer to Trim Height Specifications.
7. If the measurement is outside of the specified range, replace the front springs.
8. Use your hands to lift the rear bumper approximately 38 mm (1.59 in).
9. Remove your hands and allow the vehicle to lower.
10. Use your hands to jounce the rear of the vehicle downward approximately 38 mm (1.59 in).
11. The dimension R for the left and right side of the vehicle is measured from the bottom lip of the wheel opening to the ground measured at the
center line of the rear wheel.
12. Compare the measurement to the specification table. Refer to Trim Height Specifications.
13. If the measurement is outside of the specified range, replace the rear springs.
