Trim Height Inspection Procedure
Z Height
Trim height is a predetermined measurement relating to vehicle ride height. Incorrect trim heights may cause symptoms similar to alignment
problems. Check the trim heights when you diagnose steering or vibration complaints.
The Z dimension measurement determines the proper ride height for the front end. The Z dimension is different for RWD vehicles and 4WD or
A4WD vehicles. The 4WD and A4WD vehicles have different points of measurement to determine Z height. Use the torsion bar adjusting arm in
order to adjust Z height. RWD vehicles have no adjustment and could require replacement of suspension components.
On RWD vehicles, measure Z height from the center line of the bolt of the front lower control arm down to the lower inboard corner of the ball
joint. Trim all Z heights at 67.0-79.0 mm (2.6-3.0 in).
On 4WD and A4WD vehicles, measure Z height from the center line of the pivot bolt (1) down to the lowest inboard edge of the steering knuckle
(2).
Trim all curb Z heights at 114.0-128.0 mm (4.6-5.0 in). In order to adjust Z height, turn the bolt that contacts the torsion arm as needed. One
revolution of the bolt into the nut increases the Z height by 6.0 mm (0.2 in) (1).
