Solution

1. Preparation

Tools Required: Jack stands, lug wrench, OBD-II scanner, torque wrench, basic hand tools.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to avoid any electrical shorts.

2. Inspect and Replace Brake Pads and Rotors

Raise Vehicle:
- Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheels:
- Use a lug wrench to remove the lug nuts and take off the wheels.
Inspect Brake Components:
- Check the brake pads for thickness; replace if less than 3mm.
- Inspect rotors for warping or scoring; use a micrometer to measure rotor thickness.
Replace Brake Pads:
- Remove the caliper bolts and slide the caliper off the rotor.
- Replace the old pads with new ones, ensuring proper orientation.
Replace Rotors if Necessary:
- If rotors are warped, remove them from the hub and install new rotors.
- Torque the rotor bolts to manufacturer specifications.

3. Check and Replace Suspension Components

Inspect Suspension:
- Visually check bushings, control arms, and shock absorbers for wear or damage.
Replace Worn Components:
- For any worn parts, remove the affected component using appropriate tools.
- Install new parts and torque to manufacturer specifications.

4. Perform Wheel Alignment

Alignment Check:
- After replacing components, take the vehicle to a professional for a wheel alignment.
Adjust as Necessary:
- Ensure all angles are within manufacturer specifications to prevent uneven wear.
