Servicing wheel bearings — VW

Note:

Dismantling and assembling wheel bearing as well as the pulling off and pressing in axle beam flange (axle beam not inclusive) can also occur with installed rear axle. If only the wheel bearing has to be disassembled with the installed axle, remove brake carrier completely without pulling off the brake pipes and the handbrake cables. Tie brake carrier.
