The rubber gasket forming a seal around the CV-joint is called a boot, and must be tough to stand up to the elements encountered on the underside of your car. Even normal driving conditions expose the BMW axle assembly to a great deal of abrasive dirt and grime. If you have a cracked boot around the CV-joint, you well likely develop a grinding noise when turning one direction or another if repairs are not made. If you're experiencing such a noise when turning, you'll need a replacement BMW axle assembly and quick. The longer that noise continues, the worse the damage will be. Very often CV- and U-joints are often too damaged to use once you've heard or felt grinding. Some people recommend reusing old CV or U-joints and replacing the boot alone or even as a sealed boot-assembly. However, this requires a great deal of greasy work and special tools. Busy people value saving the time, mess and hassle of replacing components by getting the whole BMW axle assembly from car-stuff.com. When you purchase the whole assembly, you will eliminate the possibility of doing all the work only to reinstall a damaged joint. Why gamble when dealing with moving parts? Car-stuff.com has very competitive prices on high-quality BMW axle assemblies that make them a very good deal, indeed.
