2
Check brake pads for wear and ensure they are within specification.
3
Examine suspension components (control arms, bushings, etc.) for damage or excessive play.
4

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Tools Required: Jack and jack stands, lug wrench, torque wrench, dial indicator, caliper gauge.

2. Remove Wheel

Loosen lug nuts slightly while the vehicle is on the ground.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Components

Inspect Brake Rotors:
- Use a dial indicator to check for warping. If warping is present beyond acceptable limits (usually 0.002 inches), replace the rotors.
Inspect Brake Pads:
- Measure the thickness of the pads. If they are below the minimum thickness (usually 3mm), replace them.
Replace Brake Rotors (if necessary):
- Remove the caliper and bracket using a socket set.
- Take off the rotor and replace it with a new one.
- Torque the caliper bracket bolts to manufacturer specifications (usually around 25-30 Nm).
Replace Brake Pads (if necessary):
- Install new brake pads into the caliper bracket.
- Reattach the caliper and torque the bolts to specifications.

4. Inspect and Replace Suspension Components (if necessary)

Check control arms and bushings for wear. Replace any damaged components.
Inspect wheel bearings; replace if there is any significant play.

5. Reassemble and Test

Reinstall the wheel and torque lug nuts to manufacturer specifications (usually 90-100 Nm).
Lower the vehicle and remove jack stands.
Test drive the vehicle to ensure vibrations are resolved.
