Curb Height Measurement
The vehicle suspension height should be measured before performing wheel alignment procedure. Also when front suspension components have been replaced. This measure must be performed with the vehicle supporting it's own weight and taken on both sides of the vehicle.
Front and rear curb heights are not adjustable. The spring selections at assembly determine curb height for acceptable appearance of the vehicle. Curb height dimensions assume full fluids (including fuel) and zero passengers. Refer to the table below for front curb height dimensions.
Vehicle curb height audits should be performed utilizing the following procedure:
NOTE:
Make sure the vehicle is in 2WD when checking curb height.
| 1 - Lower Control Arm Rear Bolt |
FRONT CURB HEIGHT
- Bounce the front of the vehicle five times.
- Measure and record the dimensions
- Measure the height from the center of the lower control arm rear bolt.
- Measure the height from the center of the front wheel to the ground.
- Subtract the lower control arm bolt height from the wheel center height to get the front curb height.

REAR CURB HEIGHT
- On each side of the vehicle, measure the height from the center of the lower control arm front bolt to the ground.
- Measure the height from the center of the rear wheel to the ground.
- Subtract the lower control arm bolt height from the wheel center height to get the rear curb height.
