Solution

1. Preparation

Gather required tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery if working on electrical components.

2. Inspect Power Steering System

Tools Required: Pliers, funnel, rags
Check the power steering fluid level using the dipstick. If low, add the manufacturer's recommended fluid.
Inspect hoses for leaks and replace any damaged or worn hoses.

3. Examine CV Joints

Tools Required: Jack, jack stands, socket set
Safely lift the front of the vehicle and secure it with jack stands.
Visually inspect CV joints and boots for tears or grease leakage.
If damaged, replace the CV joint with a new unit. Remove the wheel, and use a socket set to unbolt the axle from the hub.

4. Check Wheel Bearings

Tools Required: Torque wrench, socket set
Rotate the wheel by hand to check for grinding noises or roughness.
If the bearings are worn, remove the hub assembly and replace the bearing. Ensure to torque the hub nut to manufacturer specifications upon reassembly.

5. Assess Suspension Components

Tools Required: Torque wrench, socket set
Inspect struts, control arms, and bushings for wear or damage.
Replace any worn suspension components and ensure all bolts are torqued to specification.
