8P3959845A Volkswagen BOOT

A CV boot is basically a flexible covering, a protective shell really, for the constant velocity joint. It's made of a tough rubber material. Its job is simple: keep the grease inside the joint and dirt, water, and debris outside. Think of it like a really important seal. Now, that constant velocity joint? That’s what delivers power from your transmission to your wheels, letting them turn smoothly. It’s on the end of your driveshaft, where it connects to the wheel. Because it’s constantly moving as the suspension goes up and down and the wheels turn, it needs lubrication – that’s where the grease comes in. The boot keeps that grease contained so the joint stays properly lubricated while allowing full range of movement. If the boot tears, all that grease will fling out pretty quickly, and then dirt and water start getting into the joint. Once that happens, the joint starts wearing out rapidly. You’ll notice if it’s going bad – usually a clicking or popping sound when you turn, especially at slower speeds. That clicking gets worse and eventually it can lead to a complete failure, meaning you won't be able to drive the vehicle. Replacing just the boot is much cheaper than replacing the entire joint—and a whole lot less work. You can find these pretty easily online, places like Fixparts Online carry them. It’s one of those things it pays to address quickly, because a small tear can quickly become a big, expensive problem. Built to last: CV Boot (MPN 8P3959845A) comes with a 12-month warranty for your assurance!
