Clean dirt as well as paint and sealant residue from contact surfaces of adapter (020h) on housing of rear axle differential (3).
Remove any unevenness on surface of material using a suitable tool.
Fit sensor (020a) with magnetic sensor mount (020c) onto magnetic adapter (020h) by turning slightly.
When each measurement is taken, the side of the sensor (020a) at which the spiral cable (020b) is connected must point in the direction of travel.

False measurements can occur otherwise.
Place and hold measuring instrument with magnetic adapter (020h) and sensor (020a) on the housing of rear axle differential (3).
Aid of helper required.
Align strut fitted with spirit level (020i) so that it is horizontal, and tighten screws/bolts (020k).
