Ride/Trim Height Specifications
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.
MEASURING THE J DIMENSION
1. Use your hands in order to lift the front bumper of the vehicle up approximately 38 mm (1.5 inch). Gently remove your hands in order to allow the vehicle to lower.
2. Use your hands in order to push the front bumper of the vehicle down approximately 38 mm (1.5 inch). Remove your hands in order to allow the vehicle to rise.
3. Measure the J dimension from the left and the right frame rail to the ground 700 mm (27.56 inch) from the front wheel centerline (A dimension).
4. If the J dimension is not within 10 mm of the specification, replace the front springs.
MEASURING THE K DIMENSION
1. Use your hands in order to lift the rear bumper of the vehicle up approximately 38 mm (1.5 inch). Gently remove your hands in order to allow the vehicle to lower.
2. Use your hands in order to push the front bumper of the vehicle down approximately 38 mm (1.5 inch). Remove your hands in order to allow the vehicle to rise.
3. Measure the K dimension from the left and the right frame rail to the ground 700 mm (27.56 inch) from the rear wheel centerline (B dimension).
4. If the K dimension is not within 10 mm of the specification, replace the rear springs.
MEASURING THE Z DIMENSION
4WD Front Suspension Sectional View
2WD Front Suspension Sectional View
1. Use your hands in order to lift the front bumper of the vehicle up approximately 38 mm (1.5 inch). Gently remove your hands in order to allow the vehicle to lower.
2. Use your hands in order to push the front bumper of the vehicle down approximately 38 mm (11.5 inch). Remove your hands in order to allow the vehicle to rise.
3. Measure the Z dimension for the left and the right side of the vehicle. The Z dimension is the vertical distance measured between the centerline of the lower control arm rear bolt (2) and the bottom of the ball joint (3).
4. If the Z dimension is not within 10 mm of the specification, replace the front springs.
MEASURING THE D DIMENSION
1. Use your hands in order to lift the rear bumper of the vehicle up approximately 38 mm (1.5 inch). Gently remove your hands in order to allow the vehicle to lower.
2. Use your hands in order to push the front bumper of the vehicle down approximately 38 mm (1.5 inch). Remove your hands in order to allow the vehicle to rise.
3. Measure the D dimension for the left and the right side of the vehicle. The D dimension is the vertical distance measured between the top of the rear shock absorber reservoir (2) to the top of the rear axle housing.
4. If the D dimension is not within 10 mm of the specification, replace the rear springs.
