Solution

1. Preparation

Ensure the vehicle is parked on a level surface.
Gather tools and parts needed for inspection and repair.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect Power Steering System

Sub-steps:
1. Locate the power steering reservoir and check fluid level.
2. If low, fill with manufacturer-recommended power steering fluid.
3. Inspect the power steering pump for any signs of leaks or damage.
Tools Required: Fluid funnel, shop towels.

3. Check Wheel Bearings

Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Spin each wheel by hand to listen for grinding or roughness.
3. If noise is present, remove the wheel and inspect the bearing for wear.
4. Replace the wheel bearing if necessary.
Tools Required: Jack, jack stands, socket set, torque wrench.

4. Examine Tires

Sub-steps:
1. Inspect all tires for uneven wear patterns or damage.
2. Rotate tires if uneven wear is detected.
3. Replace tires that are worn beyond safety standards.
Tools Required: Tire pressure gauge, lug wrench.

5. Inspect Drivetrain Components

Sub-steps:
1. Inspect the driveshaft and CV joints for any signs of wear or damage.
2. Check the transmission fluid level and condition; replace if burnt or low.
3. Tighten any loose components in the drivetrain.
Tools Required: OBD-II scanner, multimeter.
