Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure with wheel chocks.
Disconnect the battery if working on electrical components.

2. Inspect and Replace Brake Components

Remove Wheel
- Loosen lug nuts and lift the vehicle using a jack.
- Remove the wheel and set it aside.
Check Brake Pads and Rotors
- Visually inspect brake pads for thickness; replace if less than 3mm.
- Inspect rotors for scoring or warping; replace if damaged.
Replace Brake Pads/Rotors (if necessary)
- Remove caliper bolts using a socket wrench and hang the caliper using a wire.
- Remove old pads and install new ones.
- Reinstall the caliper and torque bolts to manufacturer specifications (typically 20-30 lb-ft).

3. Check Differential and Drive Components

Inspect Differential Fluid
- Locate the differential fill plug and remove it.
- Check fluid level; add if low, and replace if dirty or contaminated.
Inspect CV Joints and Axles
- Look for torn boots, grease leakage, or abnormal movement in CV joints.
- Replace any damaged components as necessary.

4. Reassemble and Test

Reinstall the wheel and torque lug nuts to manufacturer specifications (typically 80-100 lb-ft).
Reconnect the battery.
Lower the vehicle and conduct a test drive for verification.
