To protect the thread, leave the nut on the pin screwed in a few turns. Press the tie rod end out of the wheel bearing housing using a ball joint puller -T40010 A-. Then unscrew the nut.
Make sure that both arms of the puller lever are parallel to each other at the moment of maximum force application; correct the position if necessary. For subsequent installation, mark the position of the nut -2- on the tie rod -1 -. While holding the tie rod end -3- from turning, loosen the locknut -2-.
Open and remove spring clamp -3- using hose clamp pliers -VAG 1921-. Remove the clamping clamp -1- and remove the bellows -2- outwards from the power steering mechanism.
Unscrew the tie rod end -3- and the nut -2- from the tie rod -1-. Pull the corrugated cover together with the spring clamp from the tie rod. If there are visible signs of corrosion, damage, wear or contamination of the gear rack, the steering mechanism assembly is replaced. If there is no visible film of lubricant on the rack, the steering mechanism is also replaced as an assembly.
Installation
Before installation, apply the lubricant supplied with the repair kit to the gear rack. It is strictly forbidden to use any other lubricant. To do this, turn the steering mechanism in both directions until it stops. For better clarity, the illustration shows the steering gear removed. Apply grease to the toothed rack on the tooth side -A- and on the pressure stop side.
Set the steering wheel to position "directly". Place new clamps and bellows on the tie rod. Screw the nut -1- and the tie rod end -3- to the marking made before removal. Tighten nut -2- with a torque wrench. At the same time, keep the tie rod end -3- from turning. The sealing surfaces of the bellows/power steering mechanism must be free of grease during installation. Push the corrugated cover with a new clamp onto the steering gear housing. Ensure the correct position of the bellows on the power steering mechanism. The bellows must fit into the groove and around the perimeter of the power steering mechanism.
Installing the clamping clamp: Observe dimension -A- max. 5.7 mm. Dimension -A- should not exceed 5.7 mm, otherwise there will be problems with tightness.
Clamp clamp -1- using steering gear pliers -VAS 6199-. Secure spring clamp -3- to bellows -2- using hose clamp pliers -VAG 1921-. Install in reverse order. It is necessary to adjust the wheel alignment angles.
