Solution

1. Preparation

Gather tools and parts.
Safety goggles and gloves should be worn.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Check Power Steering Fluid

Locate the power steering reservoir.
Remove the cap and inspect fluid level; if low, top off with manufacturer-recommended fluid.
If fluid is dark or contaminated, drain and replace it.

3. Inspect for Leaks

Visually inspect power steering hoses for any signs of wear or leaks.
Use a clean cloth to wipe around the hoses and connections, checking for fresh fluid.
If leaks are found, replace damaged hoses or fittings.

4. Examine Power Steering Pump

Disconnect the power steering pump drive belt.
Inspect the pump for any signs of damage, noise, or play in the shaft.
If faulty, remove the pump using a socket set and replace it with a new unit.

5. Check Steering Rack

Raise the vehicle and support it with jack stands.
Inspect the steering rack for any binding or damage.
If issues are detected, the steering rack may need to be replaced.

6. Replace Serpentine Belt (if necessary)

If the serpentine belt is worn or loose, remove it by loosening the tensioner pulley.
Replace with a new belt according to the vehicle's specifications.
