Unscrew screws/bolts from heat sink and remove heat sink.
1. On rear axle differentials (3) with contact surfaces (4).
  Clean dirt as well as paint and sealant residue from contact surfaces (4) on housing of rear axle differential (3).
  
  Remove any unevenness on surface of material using a suitable tool.
2. On rear axle differentials (3) without contact surfaces (4).
  Clean surfaces to the left and right of housing end cover of rear axle differential (3) free of contamination and paint and sealant residues.

1. On rear axle differentials (3) with contact surfaces (4).
  Position sensor (020a) on contact surfaces (4) of housing of rear axle differential (3).
  
  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.
2. On rear axle differentials (3) without contact surfaces (4).
  Position adaptation for universal rear axle differential (3) on suitable area and mount sensor (020a) onto adaptation for universal rear axle differential (3).
