Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues while working.

2. Inspect and Replace Fluid

Tools Required: Fluid pump, clean rags, funnel.
Sub-steps:
1. Check the transmission fluid level using the dipstick. If low, refill with the manufacturer-recommended fluid type.
2. Inspect the condition of the fluid; if contaminated or burnt, consider a fluid change.

3. Inspect CV Joints and Axles

Tools Required: Jack stands, socket set, torque wrench.
Sub-steps:
1. Lift the front of the vehicle using a jack and secure it with jack stands.
2. Remove the wheel to access the CV joints and axle.
3. Inspect the CV boots for tears or leaks.
4. Check the CV joints for play or damage.
5. If damaged, replace the CV joint or axle assembly as needed.

4. Brake System Inspection

Tools Required: Brake caliper tool, socket set.
Sub-steps:
1. Remove the brake caliper and inspect brake pads and rotors for wear.
2. Look for any debris or foreign objects lodged between the rotor and brake components.
3. Replace any worn brake pads or damaged rotors.

5. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall all components, ensuring all bolts are torqued to manufacturer specifications.
2. Reconnect the battery.
3. Lower the vehicle and test drive to ensure the grinding noise is eliminated.
