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).
Note: One U.S. gallon of gasoline weights approximately 6.5 lbs. One liter of gasoline weights approximately 0.70 kg.
*
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:
*
Larger or Smaller than production wheels and tires.
*
Lifting or Lowering Kits
*
Wheel Opening Flares or Ground Affects
