GM Genuine Parts Axle Intermediate Shaft Bearings are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These bearings help protect against heat-damaging friction in the intermediate shaft. This friction is produced between rotating components that connect various shafts and gears in your GM vehicle's CV axle. 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).
