Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

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

3. Inspect and Replace Brake Components

A. Inspect Brake Rotors

Measure rotor thickness using a micrometer.
Check for warping by placing a dial indicator on the rotor surface.
If warped, replace rotors with new ones. Torque new rotor bolts to manufacturer specifications (typically around 80-100 ft-lbs).

B. Inspect Brake Pads

Remove caliper bolts using a socket set and slide the caliper off the rotor.
Check brake pad thickness; replace if below 3mm.
Install new pads and lubricate the backing with brake grease. Reattach the caliper.

4. Check Suspension and Wheel Bearings

Inspect control arms, strut mounts, and bushings for wear or damage.
Check wheel bearings by spinning the hub; replace if there is any roughness or play.
Use a torque wrench to tighten any bolts to manufacturer specifications.

5. Tire and Alignment Check

Inspect tires for uneven wear and ensure they are properly inflated.
If necessary, have the wheels aligned at a professional shop.
