Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off and cool.

2. Lift the Vehicle

Tools Required: Floor jack, jack stands
Use the floor jack to lift the front of the vehicle and secure it with jack stands.
Ensure the vehicle is stable before proceeding.

3. Inspect Suspension Components

Visually inspect the control arms, bushings, and ball joints for signs of wear or damage.
Check for play in the components by wiggling them by hand.

4. Examine CV Joints

Remove the wheel and inspect the outer CV joint for any tears in the boot or grease leakage.
If the boot is damaged, replace the CV joint.

5. Check Wheel Bearings

Grab the wheel at the top and bottom and try to rock it; any excessive play indicates a bad wheel bearing.
If necessary, replace the wheel bearing following the manufacturer's specifications for torque settings.

6. Reassemble

Reinstall the wheel and lower the vehicle.
Tighten the lug nuts to the manufacturer's specified torque.
