Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, brake cleaner, socket set, and a multimeter.
Safety Warnings: Ensure the vehicle is on a flat surface and securely supported with jack stands before working underneath.

2. Inspect and Replace Brake Components

Remove Wheel:
- Loosen lug nuts with a lug wrench.
- Raise the vehicle using a jack and support with jack stands.
- Remove the wheel.
Inspect Brake Pads and Rotors:
- Check brake pads for thickness; replace if less than 3mm.
- Inspect rotors for scoring or warping; replace if necessary.
Replace Brake Pads:
- Remove caliper bolts and detach caliper from the rotor.
- Replace old brake pads with new ones, ensuring they are installed in the correct orientation.
- Reattach the caliper and torque bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reassemble:
- Reinstall the wheel and hand-tighten lug nuts.
- Lower the vehicle and torque lug nuts to specifications (usually around 76 ft-lbs).

3. Inspect Drivetrain Components

Check CV Joints and Axles:
- Visually inspect CV joints for damage or grease leakage.
- Replace any damaged CV joint or axle assembly as needed.
Inspect Wheel Bearings:
- Spin the wheel by hand to check for roughness or grinding.
- If the wheel bearing is suspect, replace it following manufacturer guidelines.
