Disconnect the power steering pump's electrical connector and hoses.
Remove the mounting bolts securing the pump.
Install the new power steering pump, ensuring it is properly aligned.
Reconnect hoses and electrical connectors, and refill the power steering fluid.

4. Inspect and Replace Serpentine Belt (if necessary)

Tools Required: Socket set, belt tensioner tool.
Locate the serpentine belt tensioner.
Use the tensioner tool to relieve tension and remove the old belt.
Install the new serpentine belt according to the routing diagram.
Ensure the belt is seated properly on all pulleys.

5. Inspect Wheel Bearings and CV Joints

Raise the vehicle and support it securely on jack stands.
Remove the front wheels to access the wheel bearings and CV joints.
Check for play in the wheel bearings by shaking the wheel; replace if necessary.
Inspect CV joints for any signs of damage, including torn boots; replace if damaged.
