Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the negative terminal of the battery to prevent electrical issues.

2. Drain Power Steering Fluid

Place a drain pan under the steering rack to catch fluid.
Disconnect the return line from the power steering reservoir and allow fluid to drain completely.

3. Remove Steering Rack

Raise the vehicle using a jack and secure it with jack stands.
Remove the front wheels for better access.
Disconnect the tie rod ends from the steering rack using a socket set.
Remove the bolts securing the steering rack to the subframe and gently lower it out of position.

4. Inspect and Replace Seals

Clean the steering rack thoroughly to remove dirt and debris.
Inspect the seals and O-rings for wear or damage. Replace any defective seals with a new seal kit specific to the MK6 Golf.
Apply a thin layer of power steering fluid to the new seals to aid in installation.

5. Reinstall Steering Rack

Position the steering rack back into place and secure it with bolts, ensuring they are torqued to the manufacturer's specifications (typically around 30 Nm).
Reconnect the tie rod ends and ensure they are properly tightened.

6. Refill Power Steering Fluid

Reconnect the return line to the power steering reservoir.
Fill the power steering fluid reservoir with the appropriate fluid type (typically VW G002000 or equivalent).
Start the engine and turn the steering wheel from lock to lock to purge air from the system.

7. Check for Leaks

Inspect the steering rack and connections for any signs of leaks after the system has been pressurized.
