Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, socket set, torque wrench, fluid catch pan.
Ensure the vehicle is on a flat surface.
Disconnect the battery to prevent any electrical shorts while working.

2. Remove the Steering Rack

Raise the front of the vehicle and secure it with jack stands.
Remove the front wheels to access the steering components.
Disconnect the steering column from the rack by removing the universal joint bolt.
Detach the tie rod ends from the steering knuckles using a tie rod puller.
Remove the mounting bolts securing the steering rack to the subframe.
Carefully slide the steering rack out from under the vehicle.

3. Inspect and Replace Seals

With the rack removed, check the seals for damage or wear.
If the seals are damaged, replace them with a seal kit specific to the MK7 Golf.
Clean any debris from the steering rack housing before installing new seals.
Apply a light coat of power steering fluid to the new seals before installation to prevent pinching.

4. Reinstall the Steering Rack

Position the repaired or new steering rack back into place and secure it with mounting bolts.
Reattach tie rod ends to the steering knuckles and torque to manufacturer specifications (usually around 30-40 Nm, but check the service manual).
Reconnect the steering column to the rack and secure the universal joint bolt.

5. Refill Power Steering Fluid

Fill the power steering reservoir with the recommended fluid (usually CHF 202 or a similar low-viscosity fluid).
Check for any leaks around the newly installed seals and connections.

6. Test the System

Reconnect the battery.
Start the vehicle and turn the steering wheel from lock to lock to bleed the system of air.
Check the fluid level again and top off if necessary.
