Remove the damaged hose and replace it with a new one.
Tighten the clamps securely, ensuring a snug fit.

B. Replace Power Steering Pump (if leaking)

Tools Required: Socket set, pulley puller, torque wrench
Disconnect the battery to prevent electrical issues.
Remove the serpentine belt from the power steering pump pulley.
Disconnect the fluid lines and electrical connectors from the pump.
Remove the mounting bolts and take out the old pump.
Install the new pump, securing it with the mounting bolts to the specified torque (consult service manual for torque specs).
Reconnect the fluid lines and electrical connectors.

C. Repair Steering Rack (if leaking)

Tools Required: Jack, jack stands, socket set
If leaks are found at the steering rack, you may need to replace the seals or the entire rack.
Raise the vehicle and support it with jack stands.
Remove any components obstructing access to the steering rack.
Disconnect the steering shaft from the rack and remove the mounting bolts.
Replace the rack or seals as needed, ensuring to follow proper assembly procedures.

4. Refill and Bleed the Power Steering System
