Solution

1. Preparation

Gather tools: jack and jack stands, socket set, torque wrench, pry bar, and stethoscope.
Ensure the vehicle is on a flat surface and the engine is turned off.

2. Lift the Vehicle

Use the jack to raise the front of the vehicle and secure it with jack stands.
Remove the front wheels using a socket set.

3. Inspect Suspension Components

Visually check control arms and bushings for cracks, tears, or excessive wear.
Use a pry bar to test for play in the control arms and bushings.
If any components are damaged, replace them with OEM parts.

4. Inspect CV Joints

Look closely at the CV joints for any torn boots or grease leakage.
If the CV joint is damaged, replace the entire axle or the specific joint as needed.

5. Check Wheel Bearings

Grasp the wheel at 12 and 6 o'clock positions and wiggle to check for play.
If excessive play is detected, the wheel bearing needs to be replaced.

6. Reassemble and Torque

Reinstall the wheels and lower the vehicle.
Torque the lug nuts to the manufacturer's specifications (typically 90-100 ft-lbs).
Ensure all replaced components are torqued to specifications as per OEM guidelines.
