Z Height Measurement
NOTE:
All dimensions are measured vertical to the ground. Cross vehicle Z heights should be within 12 mm (0.47 in) to be considered correct.
The Z height measurement determines the proper ride height for the front end of the vehicle. Vehicles equipped with torsion bars use an adjusting arm to adjust the Z height. Vehicles without torsion bars have no adjustment and could require replacement of suspension components.
- Place hand on the front bumper and jounce the front of the vehicle. Make sure that there is at least 38 mm (1.5 in) of movement while jouncing.
- Allow the vehicle to settle into position.
- For 2WD models measure from the pivot bolt center line (3) down to the lower corner (5) of the steering knuckle (1) in order to obtain the Z height measurement (4). See Fig 1.
- For AWD models measure from the pivot bolt center line (3) down to the lower corner (5) of the steering knuckle (1) in order to obtain the Z height measurement (4). See Fig 2.
- Repeat the jouncing operation 2 more times for a total of 3 times. Use the highest and lowest measurements to calculate the average height.
- The true Z height dimension number is the average of the highest and lowest measurements. Refer to TRIM HEIGHT SPECIFICATIONS .
