What Are The Common Symptoms Of A Bad Porsche Axle CV Shaft Assembly?

Porsche cars come with modern components that are essential for a smoother ride. One such component is the constant velocity or CV axle, which is an important drivetrain part. This one functions when transferring power to the wheels from either the transmission or the vehicle's differential. It causes the wheels to drive forward. Commonly having a greased flexible joint, the axle assembly can easily flex depending on road conditions, without affecting its power delivery.

The inner joint in the CH shaft assembly is covered with a rubber boot. This protects the part from accumulating dirt and debris. Since axles are responsible in transferring power from the engine to the wheels, they can encounter high levels of stress and can wear out easily than expected. It is best to spot the common symptoms of a bad Porsche axle CV shaft assembly so that you can give it the attention that it needs before it can cause stress to you.


One symptom of a worn-out CV shaft assembly is when grease is found either along the underside of the vehicle or the tire's inside edge. This results from a torn boot that leaks the grease, and is tossed around as the axle turns. When neglected, this can lead to CV joint failure since dirt and debris can easily get into the boot, damaging the joint later.

Loud Noises

One of the most common symptoms of a failing axle shaft assembly is that audible clicking sound that you hear when you make a turn. This is a sign of an excessively worn joints. At this time, joints have become loose that is why they produce that clicking noise. Clicks become louder when you make faster and sharper turns and the sound usually comes from the side where the faulty CV shaft assembly is located.

Excessive Vibration

Have you ever experienced driving and you noticed that there are excessive vibrations coming from the axle? This is one of the most common symptom of a bad CV axle. The vibration comes from the fact that the CV axle's balance gets affected while it rotates. This vibration increases when you increase your speed as well.

When you encounter excessive vibration while driving, it is possible for the shafts to interfere with handling of the ride. This can affect the overall comfort as well as safety of the automobile. In this case, the CV axle will already need to be replaced, especially when it has been damaged by these vibrations.

Your car's CV axles act as the connection between your wheels and your engine. If you suspect that the axles have gone bad even when they have not reached their lifespan, it will be best to have them inspected. From there, the mechanic can recommend either repair or replacement of the assembly, depending on the severity of its condition.

It always pays to give any of the above symptoms some thought. Never neglect them, regardless if you just started noticing them or they have been there for a long time already. What matters is you get the problem solved immediately so that you can enjoy driving your luxury car once more.
