Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Use wheel chocks to prevent movement.

2. Inspect and Remove Wheels

Tools Required: Jack, jack stands, lug wrench
Loosen lug nuts slightly while the vehicle is on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheels.

3. Inspect Brake Components

Tools Required: Dial indicator, brake caliper tool
Check the brake rotors with a dial indicator for any warping. Replace if out of specification.
Inspect brake pads for wear; replace if less than 3mm thickness or unevenly worn.

4. Inspect Suspension Components

Visually inspect control arms, bushings, and tie rods for wear or damage.
Use a pry bar to check for excessive play in bushings and joints.
Replace any damaged components.

5. Reassemble and Test

Reinstall the wheels and hand-tighten the lug nuts.
Lower the vehicle and torque lug nuts to the manufacturer’s specifications (usually around 100-120 ft-lbs).
Test drive the vehicle to ensure the shaking has been resolved.
