Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Inspect and Refill Power Steering Fluid

Locate the power steering fluid reservoir.
Remove the cap and check the fluid level; if low, add the correct type of power steering fluid (consult owner’s manual for specifications).
Start the engine, turn the steering wheel from lock to lock to circulate fluid, and recheck the fluid level.

3. Check for Leaks

Inspect all power steering hoses and connections for signs of leaks.
If leaks are found, replace the damaged hoses or fittings.
Tighten any loose connections.

4. Test and Replace Power Steering Pump

Start the engine and listen for abnormal noises from the power steering pump.
If noisy, detach the pump from its mounting, remove the fluid lines, and replace it with a new pump.
Reconnect the lines, ensuring they are secure, and refill the reservoir with power steering fluid.

5. Inspect Serpentine Belt

Check the serpentine belt for cracks, fraying, or signs of wear.
If worn, remove the belt by relieving tension with a belt tensioner tool.
Replace with a new belt, ensuring proper routing and tension.

6. Examine Steering Rack

If the problem persists, inspect the steering rack for damage or excessive play.
If worn, replace the steering rack according to service manual specifications.
