Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery for safety.

2. Inspect Front Suspension

Tools Required: Jack and jack stands, wrench set, torque wrench.
Raise the front of the vehicle using a jack and secure it with jack stands.
Visually inspect control arms, tie rods, and bushings for wear or damage.
Use a wrench to check for looseness in the bolt connections; torque to manufacturer specifications if needed.

3. Check Power Steering System

Tools Required: Fluid siphon or pump, power steering fluid.
Inspect the power steering fluid reservoir for level and condition.
If fluid is low, fill with the recommended fluid type; if contaminated, plan for a full system flush.
Check hoses for leaks or cracks.

4. Inspect Wheel Bearings

Tools Required: Socket set, pry bar.
Remove the wheel and tire assembly.
Spin the hub to check for roughness or grinding; if resistance is felt, replace the wheel bearing.
If necessary, use a pry bar to check for play in the hub assembly.

5. Examine Tires

Tools Required: Tire pressure gauge, tread depth gauge.
Check tire pressure and inflate to the manufacturer's specifications.
Inspect the tread depth and look for signs of uneven wear that may indicate misalignment or suspension issues.
