Removing

• If the bellow is faulty, moisture and dirt will penetrate into steering gear. There must be a noticeable grease film present on steering rack in area of splines. If grease film is not present, steering gear must be replaced. Steering gear must also be replaced if there is corrosion or steering gear is damaged or worn out.

- Place the vehicle on a hoist.

- Remove the wheel.

- Turn steering wheel into straight ahead position.

- Remove the noise insulation.

- Clean the power steering gear and subframe in the boot area.


• While doing this, no dirt must enter the steering gear through the faulty bellows.

- Unscrew the nut - 1 - from the joint pin - 2 - on the tie rod end as far as required to make it flush with the threading on the joint pin. Counterhold it if you have to when loosening.






• Turn the nut a couple of turns on the pin to protect the threading.

- Use the (T40010 A) to force the tie rod end off of the wheel bearing housing. Next, remove the nut.






• Make sure that both lever arms on the puller are parallel to each other when you exert a great deal of force on them; adjust them so that they are parallel, if necessary.

- Mark the position of the nut - 2 - on the tie rod - 1 - for installation later.






- Loosen nut - 2 -, counterhold on tie rod end - 3 - while doing this.

- Open and remove the spring clip - 3 - using the (V.A.G 1921).






- Remove the clamping sleeve - 1 - and remove the boot - 3 - outward from the power steering gear.

- Remove the tie rod end - 3 - and nut - 2 - from the tie rod - 1 -.






- Pull off bellows with spring clamp from tie rod.

• 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

Before installing, coat the steering rack with the grease supplied in the repair set.


Do not use other grease under any circumstances.

For this purpose, turn steering to stop toward both sides in succession.

For clearer illustration, steering gear has been removed in the illustration.

- Grease the steering rack on the toothed side - A - and on the thrust piece side with grease.






- Turn steering wheel into straight ahead position.

- Guide new clamp and bellows onto tie rod.

- Install the nut - 1 - and tie rod - 3 - up to the marking applied during removal.






- Tighten the nut - 2 - to the specification. Counterhold the tie rod end - 3 -.

• The boot/power steering gear sealing surface must be free of grease when installing.

- Slide the boot onto the steering gear housing with a new clamp.

- Make sure the boot is seated correctly on the power steering gear.

- The boot must fit in the groove and on the contour of the power steering gear.

Clamping Sleeves, Installing

Make sure that dimension - A - of 5.7 mm maximum is observed. Dimension - A - must never be greater than 5.7 mm, otherwise there may be problems with the seal.






- Tighten the clamp - 1 - using the (VAS 6199).






- Secure the spring clamp - 3 - on the boot - 2 - using the (V.A.G 1921).

Further installation is in the reverse sequence to removal.
