Z Height Measurement

WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: 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.
  1. Lift the front bumper of the vehicle up about 38 mm (1.5 in). Gently remove your hands. Let the vehicle settle. Repeat this operation for a total of 3 times.
  2. Measure from bottom surface of the cradle (in line with the ball joint) to the bottom of the lower ball joint in order to obtain the Z height measurement. See Fig 1.
  3. Push the front bumper of the vehicle down about 38 mm (1.5 in). Gently remove your hands.
  4. Allow the vehicle to settle into position. Repeat the jouncing operation 2 more times for a total of 3 times.
  5. Measure the Z dimension. The true Z height dimension number is the average of the high and the low measurements. See TRIM HEIGHT SPECIFICATIONS .
