Measuring the D Height
WARNING: This page is about a different car, the 2016 GMC Acadia, 2016 Chevrolet Traverse, and 2016 Buick Enclave. However, it is still accessible from the selected car via links, so may be relevant.
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.
- Use the outer flat spot 2 on the knuckle as the reference point for the D height measurement.
- Measure from the outer on the knuckle to the center of the lower control arm bolt (1).
- 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
