t  Hydraulic wheel bearing tool -V.A.G 1459 B- t  Hollow plunger cylinder -HKZ-15- with hydraulic thrust piece -E-0-204-T- t  Pull rod -E-0-217+218- t  Special nut -E-8-214- t  Thrust piece -E-13-1-

t  Supplementary set -V.A.G 1459 B/2- t  Splitter -E-37- t  Bell -E-40- t  Thrust piece -E-43- t  Thrust sleeve -E-44-1- Removing –  Loosen hexagon bolt for drive shaft when vehicle is standing on its wheels (otherwise danger of accident). –  Remove wheel and raise vehicle. –  Pull ABS speed sensor out of wheel bearing housing.

–  Separate bolted connection for wheel bearing housing/lower swivel joint -arrow-. –  Remove hexagon bolt for drive shaft. –  Swing wheel bearing housing out of the way. –  Remove drive shaft from wheel bearing housing and tie up. The drive shaft must not hang down! The inner joint will otherwise be damaged through overflexing.

–  Remove brake carrier and brake caliper -arrows- and tie to body with wire. –  Remove brake disc and cover plate.   Note Position engine and gearbox jack -V.A.G 1383/A- under vehicle (risk of parts falling down as wheel hub and bearing are pulled out). Pulling out hub

–  Install separating device-1- between wheel bearing housing and wheel hub and tension. Installation position: Flat sides of plates face to wheel hub. –  Assemble bell-2-, hollow plunger cylinder-3- with pull rod and special nut-4-. –  Hold appliance firmly and pull wheel hub out. 1 -  Splitter -E-37- 2 -  Bell -E-40- 3 -  Hollow plunger cylinder -HKZ-15- 4 -  Special nut - E-8-214- and pull rod 5 -  High pressure hose with quick-action coupling Pulling out wheel bearing –  Remove circlip.

–  Assemble thrust piece-1- with shoulder towards bearing, thrust sleeve-2- with four stepped inner collars towards wheel bearing housing, hollow plunger cylinder-3- with pull rod and special nut-4-. –  Operate pump and pull out the wheel bearing. 1 -  Thrust piece -E-13-1- 2 -  Thrust sleeve -E-44-1- 3 -  Hollow plunger cylinder -HKZ-15- 4 -  Special nut - E-8-214- and pull rod 5 -  High pressure hose with quick-action coupling Pulling inner race off hub

Use only puller with clamp clip -A-, e.g. -Kukko 204/2- (commercially available). Pressing in wheel bearing –  Grease drilling surfaces in wheel bearing housing completely with Molykote grease -N 052 723 00-. Use grease sachet from repair set.

–  Position wheel bearing -1-, thrust piece-2- (place collar in bearing) andhollow plunger cylinder-3- with pull rod on wheel bearing housing. –  Fit thrust piece-4- with chamfer towards wheel bearing housing and special nut-5- from interior. –  Press wheel bearing in by operating the pump. –  Insert circlip with long nose pliers. 1 -  Wheel bearing 2 -  Thrust piece -VAS 6016- 3 -  Hollow plunger cylinder -HKZ-15- 4 -  Thrust piece -E-43- 5 -  Special nut - E-8-214- and pull rod 6 -  High pressure hose with quick-action coupling Pressing in wheel hub

–  Position wheel hub -1- and hollow plunger cylinder-2- with pull rod on wheel bearing. –  Fit special nut-4- and thrust piece-3- with collar towards special nut from interior. –  Press in hub by operating the pump. 1 -  Hub 2 -  Hollow plunger cylinder -HKZ-15- 3 -  Thrust piece -E-5- 4 -  Special nut - E-8-214- and pull rod 5 -  High pressure hose with quick-action coupling Further assembly work is carried out in the reverse order.
