Removing
Replace the boot each time it is removed.
If the boot is faulty, moisture and dirt will penetrate into steering gear. There must be a noticeable grease film present on the steering rack in the area of the 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. Counter hold when loosening.
To protect thread, screw nut on pin a few turns.
- Press off tie 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.
- Counter hold the tie rod end - 3 - and loosen the nut - 2 -.
- Open and remove the spring clip - 3 - using the (V.A.G 1921).
- Remove the clamp - 1 - and remove the boot - 2 - from the power steering gear.
- Remove the tie rod end - 3 - and nut - 2 - from the tie rod - 1 -.
- Pull off boot 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 Parts Catalog.
