Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect Power Steering System

Tools Required: Fluid pump, funnel
Check the power steering fluid level and add fluid if low. If fluid is discolored or has debris, replace it.
Look for leaks in the power steering lines or reservoir.

3. Examine Suspension Components

Tools Required: Socket set, jack stands, pry bar
Raise the vehicle and remove the front wheels.
Inspect control arms, bushings, and struts for cracks or excessive wear.
Use a pry bar to check for play in the bushings and joints.

4. Check CV Joints and Axles

Tools Required: Torque wrench, socket set
Inspect the CV joints for torn boots or excessive grease loss.
Rotate the wheels and listen for grinding noise; replace any damaged CV joints or axles.

5. Inspect Wheel Bearings

Tools Required: Bearing puller, torque wrench
Spin the wheel hub while listening for noise; any roughness indicates bad bearings.
Replace wheel bearings if they feel rough or have excessive play.

6. Reassemble and Test

Reinstall any components removed for inspection.
Tighten all bolts to manufacturer specifications.
Reconnect the battery terminal.
