• Unusual Movement: If your vehicle shakes or feels unstable during acceleration, it could be an axle issue.

Replacing CV Axles

Replacing a CV axle can be a straightforward task for those with mechanical knowledge. Here’s a step-by-step guide:

1. Gather Tools: You will need a jack, jack stands, a socket set, and possibly a CV axle puller.
2. Lift the Vehicle: Use the jack to raise the vehicle and secure it with jack stands.
3. Remove the Wheel: Take off the wheel to access the CV axle.
4. Disconnect the Axle: Remove the bolts securing the axle to the hub and the transmission.
5. Install the New Axle: Align and secure the new axle, ensuring all bolts are tightened to the manufacturer’s specifications.
6. Reassemble: Reattach the wheel and lower the vehicle.
