Alignment: Testing and Inspection

Trim Height Inspection

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 Vehicle Certification, Tire Placard, Anti-Theft, and Service
Parts ID Label   (See: Application and ID/Vehicle Certification, Tire Placard, Anti-Theft and Service Parts ID Label).

*

Check the fuel level. Add additional weight if necessary to simulate a full tank. 
One U.S. gallon of gasoline weighs approximately 6.5 lbs. One liter of gasoline weights approximately 0.70 kg.

*

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.

*

For vehicles equipped with automatic level control, ensure the system is functioning properly.

*

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:

-

Larger of smaller than production wheels and tires

-

Lifting or lowering kits

-

Wheel opening flares or ground affects

Measuring the P and R Heights

Note:  The left and right P and R height difference should be no more than 12 mm (0.47 in).

Use the following procedure to measure the P and R dimensions:

1. Lift the front bumper of the vehicle up about 38 mm (1.5 in).
2. Gently remove your hands and let the vehicle settle.
3. Repeat this operation 2 more times for a total of 3 times.
4. Measure vertically from the ground to the bottom lip of the wheel opening through the centerline of the front wheel, P height.
5. Push the front bumper of the vehicle down about 38 mm (1.5 in).
6. Gently remove your hands and let the vehicle settle.
7. Repeat this operation 2 more times for a total of 3 times.
8. Re-measure the P height as in step 4.
