Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Disconnect the battery if working on electronic components.

2. Inspect and Replace Brake Pads and Rotors

Sub-steps:
1. Lift the vehicle and secure it on jack stands.
2. Remove the front wheels using a socket set.
3. Inspect the brake pads for thickness; replace if below 3mm.
4. Check the rotors for grooves or warping; if warped, replace them.
5. Clean the rotor surface with brake cleaner and install new rotors if necessary.
6. Apply anti-squeal grease to the back of the new brake pads and install them.

3. Check Wheel Alignment and Balance

Sub-steps:
1. Inspect the tires for uneven wear; replace if necessary.
2. Use a wheel alignment machine to check alignment specifications.
3. Adjust alignment to factory specifications if out of tolerance.
4. If vibrations persist, balance the wheels with wheel weights.

4. Inspect Suspension Components

Sub-steps:
1. Visually check control arms, tie rods, and bushings for wear.
2. Replace any worn or damaged components as needed.
3. Ensure all bolts are torqued to manufacturer specifications.
