Remove the reservoir cap and drain the fluid completely.
Dispose of the fluid according to local regulations.

3. Remove the Steering Rack

Disconnect the hydraulic lines from the steering rack using a flare-nut wrench.
Remove the tie rod ends from the steering knuckles using a ball joint separator.
Unbolt the steering rack from its mounting brackets using a socket set.
Remove the steering rack from the vehicle carefully.

4. Inspect and Repair

Examine the steering rack for cracks, corrosion, or damaged seals.
Replace any damaged seals or O-rings to prevent leaks.
If the steering rack is beyond repair, replace it with a new or refurbished unit.

5. Reinstall the Steering Rack

Position the steering rack back into place and secure it with mounting bolts.
Reconnect the tie rod ends and torque them to manufacturer specifications.
Reattach the hydraulic lines, ensuring they are tight and leak-free.

6. Refill and Bleed the System

Fill the power steering fluid reservoir with the recommended fluid type.
Start the engine and turn the steering wheel from lock to lock several times to bleed air from the system.
Check fluid levels and top off as necessary.
