Solution

1. Preparation

Tools Required: Jack and jack stands, socket set, wrench set, power steering fluid, catch pan, rags, UV leak detection kit (optional).
Safely lift the vehicle using a jack and secure it with jack stands.
Place a catch pan under the steering rack to catch any leaking fluid.

2. Remove the Steering Rack

Disconnect the negative battery terminal to prevent electrical issues.
Drain the power steering fluid from the reservoir using a siphon or by removing the return line.
Remove the steering tie rod ends by loosening the nuts and using a tie rod puller if necessary.
Disconnect the high-pressure line and return line from the steering rack using a wrench.
Remove any mounting bolts securing the steering rack to the vehicle's subframe.
Carefully slide the steering rack out from its mounting position.

3. Inspect and Repair

Inspect the steering rack: Look for cracks or holes that could indicate the source of the leak.
If the rack is damaged beyond repair, replace it with a new or refurbished unit.
If only the seals are leaking, replace the seals according to the manufacturer's specifications.
Clean the mating surfaces thoroughly before reassembly.

4. Reinstall the Steering Rack

Position the new or repaired steering rack into place, ensuring all mounting points align properly.
Reinstall and tighten the mounting bolts to the manufacturer's torque specifications.
Reconnect the high-pressure line and return line, ensuring they are secured and leak-free.
Reconnect the tie rod ends and tighten the nuts.

5. Refill and Bleed the System

Refill the power steering reservoir with the appropriate power steering fluid.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check for leaks around the steering rack and hoses during this process.
Top off the fluid level as necessary.
