WARNING:
Wheel bearing housing raised incorrectly
- Risk of crushing
- Risk of damage to components
  1. Wear personal protective gear.
  2. Do not raise the wheel suspension higher than the normal vehicle position (vehicle resting on wheels).
Loosen the axle nut (drive shaft mounting on wheel side). (Do not remove it!) This prevents the drive shaft from slipping out when removing the wheel bearing housing. Actuate the brake while doing this.
Remove the wheel.
