Audi A4 CV Joints & Boots

A CV joint, short for a constant-velocity joint, is a device that came to supersede the universal joint in the role of a movable link capable of transmitting torque. An integral part of a modern independent suspension system, a CV joint is now installed in virtually any car, with no exception for your Audi A4. Having a tripod bearing inside, the CV joint requires lubrication and is highly vulnerable to contamination. For that reason, all of them come covered with a flexible rubber boot. The problem is that this boot isn’t particularly strong – it can be easily punctured by sharp debris. What’s worse, it’s susceptible to aging and hardening much like any other rubber item.

Once the boot cracks, the loss of lubricant and addition of dust start to ruin the bearing. Typically left unnoticed, the boot failure causes the collapse of the bearing in a matter of weeks. If you notice the issue in due time, it will be enough to replace only the boot. Otherwise, somewhat more serious spends are to come. In our Audi A4 CV joints, boots & components collection, you will find lots of replacement options, every single one of which is high-quality and adequately priced.
