Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Brake Inspection and Replacement

Remove the wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the lug nuts using a socket set and take off the wheel.
Inspect brake components:
- Examine the brake pads for thickness and wear; replace if less than 3mm.
- Check rotors for grooves or warping; replace if necessary.
Replace brake pads and rotors (if needed):
- Remove the caliper by unbolting it with a socket set.
- Slide out the old pads and replace them with new ones.
- If replacing rotors, unbolt and remove them, then install new rotors.
- Reinstall the caliper over new pads and torque bolts to manufacturer specifications (typically 25-35 ft-lbs).

3. Drivetrain Inspection and Repair

Inspect CV joints and axles:
- Check for any tears in the CV joint boots; replace if damaged.
- Look for play in the CV joints; replace the axle assembly if there is excessive movement.
Reassemble components:
- Reinstall wheel and lug nuts, tightening to manufacturer specifications (typically 76-86 ft-lbs).
- Lower the vehicle and reconnect the battery.
