Audi Workshop Service and Repair Manuals

Instead of workshop press V.A.G 1290 A, use can also be made of hydraulic removal and installation tool for wheel bearing and wheel hub V.A.G 1459 B with accessory V.A.G 1459 B /2.

Advantages:

• ‒ Wheel bearing housing need not be completely dismantled
• ‒ Track rod end is not detached from wheel bearing housing and wheel alignment is thus not necessary

Special tools and workshop equipment required

• ◆ V.A.G 1383 A Engine/gearbox lifter with universal gearbox support V.A.G 1359/2
• ◆ V.A.G 1389 A/1 Foot-operated pump with high-pressure hose

If hand pump V.A.G 1389/1 is already available in workshop, this can be converted to a foot-operated pump.

Make use of conversion kit V.A.G 1389/3 for this purpose.

Removing

• ‒ Slacken off hexagon bolt for drive shaft with vehicle standing on its wheels to avoid danger of accident.
• ‒ Remove wheel and raise vehicle.

• ‒ → Unscrew drive shaft from drive flange.

•     1 -    Hexagon socket-head bolt or multi-point socket-head bolt

• ‒ Pull wire of ABS speed sensor out of holder at brake caliper -arrow-.
• ‒ Pull ABS speed sensor out of wheel bearing housing.
• ‒ Detach brake carrier with brake caliper and attach with wire to body.
• ‒ Remove brake disc and splash plate.

• ‒ → Unscrew nut -1-, take out hexagon bolt and lift out both links -2-.

Slots in wheel bearing housing are never to be widened using a chisel or the like.

If hexagon bolt cannot be removed from wheel bearing housing, bolt and links -2- must be pressed out of wheel bearing housing .

• ‒ Screw out hexagon bolt for drive shaft.
• ‒ Swivel out wheel bearing housing.
• ‒ Take drive shaft out of wheel bearing housing and tie up.

Note:

Place gearbox lifter V.A.G 1383/A in position (danger of accident caused by falling components on removing wheel hub and wheel bearing).
