Solution

1. Preparation

Tools Required: Socket set, torque wrench, OBD-II scanner, jack stands, tire pressure gauge.
Ensure the vehicle is parked on a level surface and the engine is off.

2. Inspect Steering Components

Lift the front of the vehicle using a jack and secure with jack stands.
Visually inspect the steering rack and tie rod ends for any signs of wear or damage.
Check for any excessive play by manually moving the tie rods.

3. Check Alignment and Tire Pressure

Use a tire pressure gauge to check all tire pressures; adjust as necessary according to manufacturer specifications.
Inspect the alignment by measuring the angles; consider a professional alignment if out of spec.

4. Examine Suspension Components

Inspect control arms, bushings, and ball joints for wear.
Replace any worn components with OEM parts to maintain integrity.

5. Power Steering System Test

Check the power steering fluid level; refill if low with the recommended fluid type.
Start the vehicle and turn the steering wheel from lock to lock, listening for any unusual noises, which may indicate a failing power steering pump.

6. Reassemble and Torque Components

Tighten all components to manufacturer specifications using a torque wrench.
Reinstall any covers or shields removed during inspection.
