Important:  

*

In order to obtain the proper measurement, D will equal inner minus the outer.

*

The left and right D height difference should be no more than 12 mm (0.47 in).

Use the following procedure to measure the D height:

1. Lift the rear 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. Use D outer on the knuckle the reference point for the D height measurement.
5. Measure from the D outer on the knuckle to the center of the lower control arm bolt Inner.
6. The difference between these 2 measurements is the D height.
7. Lift the rear bumper of the vehicle up about 38 mm (1.5 in).
8. Gently remove your hands and let the vehicle settle.
9. Repeat this operation 2 more times for a total of 3 times.

10. Re-measure the D height as in step 4.
11. The true D height is the average of the measurements taken in steps 4 and 8. Refer to Trim Height Specifications  (See: Specifications/Mechanical

Specifications/Suspension/System Specifications/Trim Height Specifications) .

If any of these measurements are out of specifications, inspect for the following conditions:

*

Worn or damage suspension components
