Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to avoid any electrical issues during inspection.

2. Inspect and Tighten Components

Tools Required: Socket set, torque wrench
Inspect the undercarriage for loose bolts or components, particularly around the transmission and suspension.
Tighten any loose bolts to the manufacturer's specified torque settings.

3. Check CV Joints and Axles

Tools Required: Jack stands, pry bar
Lift the vehicle using a jack and secure it with jack stands.
Inspect the CV joints for torn boots or excessive play.
If damaged, remove the wheel and axle nut, then replace the CV joint or axle as necessary.

4. Transmission Fluid Inspection

Tools Required: Transmission fluid dipstick, funnel
Locate the transmission dipstick and check the fluid level.
If low, add the recommended type of transmission fluid.
If the fluid is dark or has a burnt smell, perform a transmission fluid change.

5. Reassembly and Testing

Reinstall any components that were removed.
Reconnect the battery.
Start the vehicle and test drive to ensure the clicking noise is resolved.
