Solution

1. Preparation

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

2. Inspect and Replace Brake Pads and Rotors

Tools Required: Socket set, brake caliper tool, torque wrench, jack, jack stands.
Sub-steps:
1. Loosen the lug nuts on the front wheels slightly before lifting the vehicle.
2. Use the jack to raise the vehicle and secure it with jack stands.
3. Remove the front wheel to access the brakes.
4. Inspect the brake pads for thickness; replace if less than 3mm.
5. Check the rotors for scoring or warping; replace if necessary.
  - If replacing rotors, remove caliper bolts, then the caliper, and finally the rotor.
  - Install new rotor, ensuring it is properly seated.
6. Install new brake pads, ensuring proper orientation and alignment.
7. Reinstall the caliper and secure with bolts; torque to manufacturer's specifications.
8. Reattach the wheel and lug nuts; lower the vehicle and torque the lug nuts.

3. Examine and Repair Suspension Components

Tools Required: Socket set, wrench set, pry bar.
Sub-steps:
1. Visually inspect suspension components for any signs of wear or damage.
2. Use a pry bar to check for play in the control arms and bushings.
3. Replace any worn or damaged components; ensure all bolts are torqued to specifications.
4. Reassemble any disassembled components.

4. Tire Inspection and Adjustment

Tools Required: Tire pressure gauge, tire balancing equipment (if necessary).
Sub-steps:
1. Check the tire pressure on all four tires; inflate or deflate as necessary to the manufacturer's specifications.
2. Inspect tires for uneven wear patterns; rotate or replace tires if needed.
3. If necessary, perform a wheel alignment to ensure proper tracking.
