Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Fluid Inspection

Tools Required: Dipstick, funnel, clean rags.
Check the transmission fluid level using the dipstick; if low, top off with manufacturer-recommended fluid.
Inspect the fluid color and smell. If dark or burnt, consider a fluid change.

3. CV Joint and Axle Inspection

Tools Required: Jack, jack stands, socket set.
Safely lift the front of the vehicle using a jack and secure it with jack stands.
Visually inspect the CV joints for torn boots or grease leakage. If damaged, proceed to replace them.

4. Transmission and Drivetrain Component Inspection

Tools Required: Torque wrench, socket set.
Check the condition of the transmission mount and engine mounts for signs of wear or damage.
Inspect the driveshaft for any signs of play or damage and replace if necessary.

5. Clean and Reassemble

Clean any debris around the components before reassembly.
Reassemble any removed components and ensure all fasteners are torqued to specifications.
