Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Disconnect the negative battery terminal to prevent electrical issues.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, fluid catch pan
Sub-steps:
1. Locate the transmission fluid dipstick and remove it.
2. Check the fluid level and condition; it should be bright red and free of debris.
3. If low or dirty, drain the old fluid using a fluid catch pan.
4. Replace with manufacturer-recommended transmission fluid, using a funnel.
5. Recheck the fluid level after running the engine for a few minutes.

3. Inspect and Replace Worn Drivetrain Components

Tools Required: Jack stands, socket set, torque wrench
Sub-steps:
1. Raise the vehicle and secure it on jack stands.
2. Inspect the CV joints and axles for any signs of wear or damage (cracks, tears in the boot).
3. If any component is damaged, remove it using the socket set and replace it with a new part.
4. Torque all components to manufacturer specifications.
5. Lower the vehicle and reconnect the negative battery terminal.
