2. Check and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, top off with the recommended fluid type.
Inspect the fluid condition; if dark or contaminated, consider flushing the system.

3. Inspect and Replace Power Steering Hoses

Visually inspect power steering hoses for cracks or leaks.
If damaged, use a wrench to disconnect the hoses from the pump and steering rack.
Install new hoses and secure with appropriate clamps, ensuring they are tight but not over-torqued.

Remove the drive belt from the power steering pump by loosening the tensioner.
Disconnect the inlet and outlet hoses from the pump.
Remove the mounting bolts and take out the old pump.
Install the new pump, ensuring to align it properly and torque the mounting bolts to manufacturer specifications.
Reconnect the hoses and reinstall the drive belt.

5. Test the System

Refill the power steering fluid if it was depleted.
Start the engine and turn the steering wheel from lock to lock to purge air from the system.
Check for leaks around the hoses and pump.
