Front axle

1. At actual vehicle height (Page 44 - 2 / 44 - 2a), measure the distance between the tire contact surface and the measuring point on the rear link bearing.

2b) If spring struts are adjustable the vehicle height is adjusted at the front axle by turning the adjusting nut. Set the wheels to a suitable lock to give access to the adjusting nut (do not raise the vehicle). Should the vehicle be raised, restore to actual vehicle height before checking the height again.

Adjusting nut

- turn to the right = vehicle higher

- turn to the left = vehicle lower

Adjust using the same tools as for the rear axle.

Nominal value 180 ± 10 mm max. difference between left and right 10 mm.

Rear axle

1. At actual vehicle height

(Page 44 - 2 / 44 - 2a) measure from tire contact surface to measuring point on the cross member.

specified value 173 ± 10 mm max. difference between left and right 10 mm

2. The vehicle height is adjusted at the rear axle by turning the adjusting nut. Use an extended hook wrench (with welded-on pipe) or Special Tool

VW 637/2 (lever) to turn the nut accordingly. Do not raise the vehicle.

Adjusting nut

- turn to the right = vehicle higher

- turn to the left = vehicle lower

If Bilstein spring struts are installed, the adjusting range for lowering the vehicle is limited by a stop for the adjusting nut. If Boge spring struts are installed, the adjusting nut turns too easily at the lowest position. This means that the lower spring seat no longer has contact with the adjusting nut, but with the threaded sleeve. Under normal conditions, this acceptable range is not reached (if height is adjusted according to regulations).

Rear axle

1. At actual vehicle height

(Page 44 - 2 / 44 - 2a) measure from tire contact surface to measuring point on the cross member.
