Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical issues during repair.

2. Inspect and Replace Brake Components

Sub-steps:
1. Remove the wheel to access the brake assembly using a socket set.
2. Inspect the brake caliper for sticking or corrosion. If faulty, remove it using a wrench.
3. Check the brake pads for wear. Replace if thickness is below manufacturer specifications.
4. Inspect the brake rotor for warping or scoring. Replace if necessary.
5. Reassemble the brake components and ensure all bolts are torqued to manufacturer specifications (typically 80-100 Nm for caliper bolts).

3. Check Drivetrain Components

Sub-steps:
1. Lift the vehicle securely using jack stands.
2. Inspect the driveshaft for any signs of damage or binding.
3. Rotate the driveshaft by hand to check for smooth movement.
4. Inspect the differential fluid level and condition. Top up or change fluid if contaminated.
5. Reinstall any removed components and lower the vehicle.
