Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, jack and jack stands, torque wrench, flashlight, fluid catch pan.
Safety Warnings: Ensure the vehicle is on a level surface and securely supported before working underneath.

2. Fluid Inspection

Check the transmission fluid level:
1. Locate the transmission dipstick (if equipped) or access the fill plug.
2. Remove the dipstick or fill plug, and inspect fluid level; add fluid if low.
3. Check the fluid condition for discoloration or burnt smell.
4. If the fluid is degraded, drain and replace it with the manufacturer's recommended fluid.

3. Drive Shaft and CV Joints Inspection

Inspect the drive shaft and CV joints:
1. Lift the vehicle securely using a jack and jack stands.
2. Visually inspect the drive shaft for any signs of wear or damage, like cracks or rust.
3. Check the CV joints for torn boots or excessive play.
4. If damaged, replace the affected components.

4. Rear Differential Inspection

Check the rear differential:
1. Remove the fill plug and inspect the fluid level.
2. If low, add the appropriate gear oil.
3. Check for metal shavings or debris in the differential housing; if present, a rebuild may be necessary.

5. Brake System Inspection

Examine the brake components:
1. Inspect brake pads and rotors for wear.
2. Ensure calipers are functioning properly and not binding.
3. Replace any worn or damaged brake components.
