The GMC Sierra CV Boot is a flexible cover that keeps the lubricating grease around the constant velocity joint while blocking the entry of road grit and water. It allows for free pivoting of the axle when steering or suspension travels. Constructed of tough rubber or thermoplastic, the CV Boot bends with every halfshaft angle change, allowing all that power to stay smooth. If the CV Boot tears, grease will leak out and dirt will slip in, causing clicking noises and subsequent failure. Initially, trucks had soft neoprene sleeves, while later models incorporated heat resistant thermoplastic elastomer boots. However, both varieties use molded ribs and metal bands that secure the CV Boot tightly to the joint housing and shaft for a proper leakproof seal. Sierra drivers get a visual check for cracks, which enables them to change a damaged boot before it causes excessive wear on an expensive axle. All modern GMC pickups with independent front suspension or four wheel drive still make use of constant velocity joints, which is why the CV Boot is applied for protection of the CV joints on the drivetrain, on inner and outer shaft ends. Timely care will keep the Sierra drivetrain clean and quiet and prevent expensive repair costs for GMC owners.
