• Open-Jaw Torque Wrench Insert (V.A.G 1923)

• Adapter (3313)

• Friction meter (VAS 6222)

• Wet and Dry Vacuum Cleaner for example (V.A.G 1373)

• Cordless Drill for example (VAS 5036)

• 4 mm drill bit

• Pliers for outer securing rings, for example HAZET (1847-2)

• Dial Gauge

Removing

- Remove the steering gear. Refer to => [ Steering Gear ] Steering Gear.

- Clean steering gear in area of adjustment screw for mechanical thrust piece.

- Tension steering gear using 2 bolts M10 x 80 as depicted in the illustration.

- Determine starting torque of steering.

- Turn steering into straight ahead position using (T10304).

For this purpose, dimension - a - = 25.5 mm.

- Slide bellows - 1 - without clamp back onto steering gear housing.

- Rotate steering gear in mounting bracket so that thrust piece with adjustment screw points upward.

- Drill the 6 peenings out using a 4 mm drill bit until reaching dimension - a -.

Dimension - a - = 3 mm

Do not drill deeper than 3 mm.

- Vacuum up drill shavings completely from steering gear housing using e.g. wet and dry vacuum cleaner (V.A.G 1373).

- Remove the adjustment screw.

- Remove spring and sealing ring - arrow -.

- Pull thrust piece out of steering gear housing using suitable pliers e.g. HAZET (1847-2).

• If corrosion, damage, wear-out or first signs of soiling on steering rack can be seen, complete steering gear must be replaced.

• If no grease film is visible on steering rack, steering gear must also be replaced completely.

Installing and Adjusting

- Coat new thrust piece (contact surface at steering gear), sealing ring and hole in steering gear housing with grease (G 052 192 A1) supplied - arrows -.

Do not use other grease under any circumstances.

- Insert thrust piece by hand into steering gear housing.

- Install new sealing ring - arrow - and new spring.

- Tighten new adjustment screw to 40 Nm.

- Peen the adjustment screw 6 times - arrows - using a punch.

Punch points must be applied 2 graduation lines next to the drill out punch points.

- Mark one graduation line of adjustment screw on the steering gear housing - 1 -.

- Remove the adjustment screw 6 graduation lines toward left - 2 -.

While doing this, a loosening torque of at least 15 Nm must be obtained.

If Loosening Torque is Not Obtained:

- Tighten adjustment screw to 40 Nm again.

- Reinforce the 6 peenings using a punch.

- Check applied marking of adjustment screw graduation line on steering gear housing, apply the marking again if necessary.

- Remove the adjustment screw 6 graduation lines toward left.

A loosening torque of at least 15 Nm must be obtained.

- Remove rubber plug from adjustment screw.

- Attach a dial gauge with 0.001 graduations as depicted in the illustration.

- Tension dial gauge to 1 mm preload.

- Rotate to tighten steering rack using (V.A.G 1331) and (V.A.G 1923) on tie rod to 40 Nm in one direction. When (V.A.G 1331) disengages, set dial gauge to "0".

- Now remove (V.A.G 1331) from tie rod.

- Read off value indicated on dial gauge.

Specified value: 0.005 to 0.05 mm

- Turn steering using (T10304) from left stop to right stop. Observe values indicating on dial gauge while doing this.

Specified value: 0.05 to 0.12 mm

• If specified values for steering rack play are not obtained, steering gear must be replaced completely!

- Remove dial gauge and adapter, press rubber plug in adjustment screw.

- Pull off left bellows from steering gear housing.

- Turn steering from left stop to right stop, while doing this grease visible area of steering rack with grease (G 052 192 A1) supplied.

Do not use other grease under any circumstances.

- Install left bellows onto steering gear housing with new clamp.

- Determine starting torque of steering.

- First turn steering toward right in direction of travel until it stops.

- Now turn steering uniformly toward left until it stops on friction meter, e.g. (VAS 6222). Read off steering torque while doing this.

Specified value: 3 +/- 2 Nm

1 Friction meter, e.g. (VAS 6222)
2 24 mm socket

If Steering Torque is Exceeded:

- Loosen thrust piece adjusting screws on steering pinion side about one graduation line (turn adjustment screws toward left).

- Then, check steering torque.

If Steering Torque Falls Short:

- Install thrust piece adjusting screws on steering pinion side about one graduation line (turn adjustment screws toward right).

- Then, check steering torque.

- Steering gear, installing => [ Steering Gear ] Steering Gear.

- Perform vehicle alignment => [ Wheel Alignment ] Wheel Alignment.

- Perform basic setting for Steering Angle Sensor (G85) via vehicle diagnostic tester "Guided Fault Finding".

- Then perform basic setting of steering system via vehicle diagnostic tester "Guided Fault Finding".
