Solution

1. Preparation

Gather tools and parts needed for repair.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and goggles.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and check the fluid level; add manufacturer-recommended fluid if low.
Inspect the fluid for contamination (dark color or debris).

3. Inspect Serpentine Belt

With the engine off, locate the serpentine belt.
Check for signs of wear, cracking, or fraying.
If damaged, proceed to remove and replace the belt.
- To remove, use a socket wrench to release tension on the belt tensioner.
- Slide the belt off the pulleys and replace it with a new belt.

4. Check Power Steering Pump

With the engine running, listen for any abnormal noises coming from the power steering pump.
If noise persists, disconnect the power steering pump and inspect for internal damage.
Replace the pump if necessary, following these sub-steps:
- Disconnect the power steering lines and electrical connectors.
- Remove mounting bolts and lift out the pump.
- Install the new pump by reversing the removal steps, ensuring to torque bolts to manufacturer specifications.

5. Inspect Steering Rack and Tie Rod Ends

Raise the vehicle safely using jack stands.
Inspect the steering rack for leaks or damage.
Check tie rod ends for play or wear; replace if necessary.
- To replace tie rod ends, remove the cotter pin and nut, then pull out the tie rod end from the steering knuckle.
