Fig 3: Separating Out Put Flange

Unscrew center bearing.

Preload center bearing in direction of travel to dimension (A) 2 ... 4 mm.

Fig 1: Identifying Preload Center Bearing In Direction Of Travel To Dimension (A) 2 ... 4 mm

Tightening Torque, refer to 26 11 6AZ PROPELLER SHAFT ASSEMBLY .

CAUTION: Do not let propeller shaft fall into joints.

Joints and rubber sleeve on constant velocity joint can be damaged.

Bend propeller shaft downwards on center bearing.

Fig 3: Bending Propeller Shaft Downwards On Center Bearing

Remove constant velocity joint from final drive and lift propeller shaft off transmission output flange.

NOTE: Protect constant velocity joint from dirt with transport cap or similar item.

Top up grease fill.

Grease, refer to BMW Parts Service.

Remove constant velocity joint (1) up to detent.

Remove grease from sealing faces of constant velocity joint and input flange.

Replace seal (2).

Use new nuts.

Fit propeller shaft with dismantled constant velocity joint to input flange of final drive.

Fig 1: Removing Constant Velocity Joint

CAUTION: During assembly, the constant velocity joint must not be pushed together because the grease fill can force away the sealing ring, preventing the constant velocity joint from providing an effective seal.

Alternately tighten 2 opposing nuts to draw constant velocity joint evenly into the input flange.

Then tighten down the remaining nuts.

Tightening Torque, refer to 26 11 4AZ PROPELLER SHAFT ASSEMBLY .

Check centering mount (4).
