D Height Measurement
The D height dimension measurement determines the proper rear end ride height. There is no adjustment procedure. Repair may require replacement of
suspension components.
Use the following procedure to check the D dimension:
1. Use your hands to lift the rear bumper approximately 38 mm (1.59 in).
2. Remove your hands and allow the vehicle to lower.
3. Use your hands to jounce the rear of the vehicle downward approximately 38 mm (1.59 in).
4. Remove your hands and allow the vehicle to rise.
5. Repeat this operation a total of 3 times.
6. Measure the vertical distance between the bottom edge of the upper spring seat to the bottom of the notch in the lower spring seat. This
measurement is the D height.
7. Compare the measurement to the specification table. Refer to Trim Height Specifications.
8. If these measurements are out of specifications, inspect for the following conditions:
*
Worn or damaged suspension components
*
Collision damage
