Porsche CV Axle Bolt - German 99951004701

Product Information

The CV (Constant Velocity) axle assembly is responsible for transferring torque and rotational power from the transmission to the wheels while allowing for suspension movement and steering articulation. The CV axle consists of a shaft with joints at both ends: a CV joint that connects the axle to the transmission and another CV joint that connects the axle to the wheel hub. This design allows the axle to handle changes in angle and length as the vehicle moves, especially when turning or going over bumps.

• Clicking or Popping Noises: One of the most common signs of a failing CV axle is a clicking or popping noise when turning the vehicle. This noise typically occurs when the CV joint is damaged or worn out, especially during sharp turns.
• Vibration While Driving: A failing CV axle can cause noticeable vibrations while driving, especially at higher speeds. This vibration may indicate that the axle is bent, or damaged, or that the CV joints are worn out.
• Grease Leaks: If the CV axle boot tears or cracks, grease can leak out. You may notice grease on the inside of the wheel or around the CV joint. This can lead to increased wear on the joint due to a lack of lubrication.
