Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent electrical shorts.

2. Inspect Steering Components

Tools Required: Socket set, torque wrench, pry bar.
Inspect the tie rods, control arms, and steering rack for any damage.
Check for any loose bolts and tighten to manufacturer's specifications.
Use a pry bar to check for play in the steering components; replace if excessive play is found.

3. Check Power Steering Fluid

Tools Required: Clean rag, funnel.
Remove the power steering fluid reservoir cap.
Check the fluid level; if low, top up with manufacturer-recommended power steering fluid.
Inspect the fluid for contamination; replace if fluid is dirty or has a burnt smell.

4. Test Power Steering Pump

Tools Required: Pressure gauge for power steering.
Reconnect the battery and start the engine.
Connect the pressure gauge to the power steering pump outlet.
Check the pressure when turning the steering wheel; it should meet manufacturer specifications. Replace the pump if pressure is outside the normal range.

5. Inspect Tires and Alignment

Tools Required: Tire pressure gauge, alignment tools.
Check tire pressure with a gauge and inflate to the recommended PSI.
Inspect tire tread for uneven wear; replace tires if necessary.
Perform a wheel alignment to ensure proper handling and steering response.
