If your Volkswagen Jetta is producing unwanted noise, perhaps your axle assembly is damaged. Damaged axle assembly is common especially if a vehicle is often traveled in difficult roads. The axle assembly that is used in your vehicle combines the axle shaft as well as the CV joint. You may also find here the U-joint. This assembly works in transmitting the rotational force produced from the transmission to the wheels. It is located in front of the 4-wheel drive vehicles. Transferring the rotational force actually requires it to be seamless that is why every part in the assembly is well greased and packed away from each other. And the boot or the rubber gasket that seals around the CV joint is tough which keeps the abrasive dirt and dust away from the joints. Flushing the contaminants away from the joints could be a tough job. In fact, this could lead to a lot of failure. These joints may extremely suffer from the contaminants. In addition, some may not actually produce noise or sounds which makes it difficult to diagnose the problem. This is the reason why checking its condition regularly must be practiced. Once a damaged axle assembly is ignored, the stress that is produced may result to a poor performance of the vehicle as well as to its handling condition. Replacing this old axle assembly with our CVU axle assembly could be an advantage. Any of the 1999-2004 models of Volkswagen Jetta can actually use the CVU axle assembly. The CVU6844 CVU axle assembly can be found in our extensive collection of auto replacement parts and accessories.
