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:

Lift the rear bumper of the vehicle up about 38 mm (1.5 in).
Gently remove your hands and let the vehicle settle.
Repeat this operation 2 more times for a total of 3 times.
Measure from the center of the inner pivot bolt (A) to the alignment rack.
Measure from the center of the outer pivot bolt (B) to the alignment rack.
The difference between these 2 measurements is the D height.
Lift the rear bumper of the vehicle up about 38 mm (1.5 in).
Gently remove your hands and let the vehicle settle.
Repeat this operation 2 more times for a total of 3 times.
Re-measure the D height as in step 4.
The true D height is the average of the measurements taken in steps 4 and 8. Refer to Trim Height Specifications .

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

Worn or damage suspension components
Collision damage
