These seals help keep dirt and water out of your axle shaft assembly and seal in lubricant. They conform to the rotating surface to help provide leak-free operation. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
