1. -1- - Wheel bearing housing (Carry out a close visual inspection of the seat of the wheel bearing. There must be no scores, grooves or similar deformations.)
2. -2- - Wheel bearing (The wheel bearing can no longer be used once it is removed. Use a new wheel bearing. Do not press on the inner race. Insert the wheel bearing with the magnetic multiple-pole ring towards the drive shaft. Check the magnetic side (e.g., with a paper clip). Do not use magnets or screw drivers for the check!
3. -3- - Circlip (Use new circlip.)
4. -4- - Wheel hub (Pull inner race off separately from the wheel bearing. Carry out a close visual inspection of the seat of the wheel hub. There must be no scores, grooves or similar deformations on the hub.)
5. -5- - Axle nut (Lock nut - always replace. Grease contact surface with a little Optimoly TA. Use the specified tightening torque.)
