If a hose is leaking, remove the clamps using a socket set.
Cut out the damaged section of the hose using a hose cutter.
Attach a new hose section using appropriate hose clamps, ensuring a secure fit.

B. Replacing the Power Steering Pump

Remove the power steering fluid reservoir to access the pump.
Disconnect the power steering lines from the pump using a wrench.
Unbolt the pump from its mounting bracket and remove it.
Install the new power steering pump and torque to manufacturer specifications.
Reconnect the power steering lines and reservoir.

C. Sealing Steering Rack Leaks

Remove any undercarriage panels blocking access to the steering rack.
If leaking from the seals, replace the seals carefully following manufacturer instructions.
Reinstall any removed components.

4. Refill Power Steering Fluid

Refill the power steering system with the recommended fluid type (check owner's manual for specifications).
Start the vehicle and turn the steering wheel from lock to lock to bleed air from the system.

5. Final Inspection

Check for leaks around repaired components.
Top off fluid levels if necessary.
