Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery negative terminal to ensure safety during repairs.

2. Inspect and Replace CV Joints/Axles (if applicable)

Lift the Vehicle
- Use a jack to raise the front of the vehicle and secure it with jack stands.
- Tools Required: Jack, jack stands, wheel chocks.
Remove Wheel
- Remove the wheel on the side where the clicking noise is observed.
- Tools Required: Lug wrench.
Inspect CV Joint
- Visually inspect the CV joint for any signs of wear, tearing, or leaking grease.
- If damaged, proceed with replacement.
Remove the CV Axle
- Remove any retaining clips and disconnect the axle from the wheel assembly and differential.
- Use a socket set to remove bolts as needed.
- Tools Required: Socket set, pry bar (if necessary).
Install New CV Axle
- Install the new axle by reversing the removal steps.
- Ensure all connections are secure and torque the bolts to the manufacturer’s specifications.

3. Check and Replace Transmission Fluid (if applicable)

Locate Transmission Fluid Dipstick
- For automatic transmissions, locate the dipstick (if applicable) or access the fill plug.
Check Fluid Level
