1 Place both bearing caps (1) on the rear axle housing and tighten the securing bolts finger-tight.
Observe the installation position of the bearing caps (1).
2 Place one of the two fitting pieces (2) in each bearing bore and insert the measuring shaft (3) into the fitting pieces (2).

3 Measure dimension 'A' with the vernier depth gauge (4).
Dimension 'A' = dimension between the end faces of the differential gear housing (5) and the point of contact of the vernier depth gauge (4) on the measuring shaft (3).
4 Calculate dimension 'X'.
Dimension 'X' = dimension 'A' + (0.5 x diameterof measuring shaft )
E.g.: dimension 'X' = 285.15 mm + 15.00 mm = 300.15 mm

5 Determine dimensions 'D' and 'E' with the vernier depth gauge (4), the measuring scale (6) and the gauge block (7) .
Dimension 'D' = dimension from point of contact of vernier depth gauge (4) on the measuring scale (6) to the flange mating surface of the pinion housing (8).
Dimension 'E' = dimension from point of contact of vernier depth gauge (4) on measuring scale (6) to end face of tapered roller bearing inner race (shown in illustration).
6 Calculate dimension 'Y'.
Dimension 'Y' = dimension 'D' - dimension 'E'
E.g.: dimension 'Y' = 130.00 mm - 54.70 = 75.30 mm
7 Read pinion dimension 'R' on the end face of the drive pinion.
E.g.: dimension 'R' = 226.0+015 = 226.15 mm
8 Determine thickness 'S' of shim (n) between mating flange of pinion housing and differential gear housing.
Thickness 'S' = 'R' + 'Y' - 'X'
E.g.:
thickness 'S' = 226.15 mm + 75.30 mm - 300.15 = 1.30 mm
