Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery for safety if working on electrical components.

2. Check Power Steering System

Tools Required: OBD-II scanner, fluid pump, funnel
- Inspect the power steering fluid reservoir for proper level.
- If low, top off with the manufacturer-recommended power steering fluid.
- If fluid is dark or contaminated, perform a fluid flush.

3. Inspect CV Joints and Axles

Tools Required: Jack, jack stands, socket set
- Raise the front of the vehicle and secure it on jack stands.
- Examine the CV joints for tearing or excessive wear.
- Spin the wheels by hand to listen for any grinding noises coming from the joints.
- If damaged, replace the CV joint or axle assembly as necessary.

4. Examine Suspension Components

Tools Required: Wrench set, torque wrench
- Inspect control arms, bushings, and struts for any signs of wear or damage.
- Check for loose or damaged mounting bolts.
- Tighten any loose bolts to manufacturer torque specifications or replace damaged components.

5. Check Wheel Bearings

Tools Required: Bearing puller, socket set
- Remove the wheel and brake assembly to access the hub.
- Spin the hub to check for roughness or grinding.
- If the bearing is faulty, replace it with a new one and ensure proper lubrication.
