Solution

1. Preparation

Gather tools and parts needed for the 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

Tools Required: Fluid siphon or turkey baster
Remove the power steering fluid reservoir cap.
Check the fluid level; it should be between the "MIN" and "MAX" marks.
If low, fill with the manufacturer's recommended fluid type (typically ATF or specific power steering fluid).
Inspect the fluid for contamination or discoloration; if dirty, replace the fluid.

3. Inspect the Power Steering System

Tools Required: Wrench set, flashlight
Visually inspect the power steering pump and lines for leaks.
If leaks are found, replace the damaged hoses or pump.
Check the pump drive belt for wear; replace if frayed or loose.

4. Examine the Steering Rack

Tools Required: Socket set
Raise the vehicle using a jack and secure it with jack stands.
Inspect the steering rack for any physical damage or binding.
Move the steering wheel back and forth while observing the rack; look for any resistance or noise.

5. Check Battery Voltage

Tools Required: Multimeter
With the vehicle off, set the multimeter to measure DC voltage.
Connect the multimeter leads to the battery terminals.
A healthy battery should read between 12.4 and 12.7 volts; if below, charge or replace the battery.

6. Reassemble and Test

Reinstall any removed components and ensure all fasteners are tightened to manufacturer specifications.
Lower the vehicle and start the engine.
Turn the steering wheel left and right to check for smooth operation.
