Measuring the Z Dimension

Measuring the Z Dimension

The Z height dimension measurement determines the proper ride height for the front end of the vehicle. There is no adjustment procedure. Repair may
require replacement of suspension components.

Use the following procedure to check the Z height dimension:

1. Use your hands to lift the front bumper approximately 38 mm (1.59 in). 
2. Remove your hands and allow the vehicle to lower.
3. Use your hands to jounce the front 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 from the bottom surface of the cradle, in line with the ball joint, to the bottom of the ball joint in order to obtain the Z height

measurement.

7. Repeat the jouncing operation 2 more times.
8. Measure the Z height dimension again.
9. The true Z height dimension number is the average of the high and the low measurements.

10. Compare the measurement to the specification table. Refer to Trim Height Specifications.
11. If these measurements are out of specifications, inspect for the following conditions:

*

Worn or damaged suspension components

*

Collision damage
