Boot

Special tools, testers and auxiliary items required

• Torque wrench (V.A.G 1331)

• Torque wrench (V.A.G 1332)

• Ring Spanner Insert (V.A.G 1332/7)

• Hose clamp pliers (V.A.G 1921)

• Locking pliers (VAS 6199)

• Ball joint puller (T40010 A)

Removing

Replace the boot each time it is removed.

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.

- Remove the front wheel.

- Set the wheels to the straight ahead position.

- Remove 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.

- Remove the nut - 1 - from the tie rod end joint pin - 2 - until it is flush with the joint pin threads. Counterhold when loosening.






To protect thread, screw nut on pin a few turns.

- Press off track rod ball joint from wheel bearing housing using (T40010 A). Remove the nut.






• Make sure that both puller lever arms are parallel to each other when using greatest force, adjust if necessary.

- Mark the installed position of the nut - 2 - on the tie rod - 1 - for 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

Install in reverse order of removal. Note the following:

• Replace the boot each time it is removed.

• Coat the inside of slits in the boot all the way around and evenly with power steering gear grease before installing. Refer to the Electronic Parts Catalog (ETKA).

• Check the seat for the boot on the steering gear for damage before installing. If the steering gear housing is damaged, replace the steering gear.

• 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.






• To grease the rack, only use power steering gear grease. Note: there are different types of grease for the left and right. For the correct allocation, refer to the Electronic Parts Catalog (ETKA).

- Set the wheels to the 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






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