Applications

Tech Note 1: Installing Snap Ring
The GM 14 Bolt Full Floating Rear Axle Hub is designed so the outer wheel bearing and cup are installed from the BACKSIDE of of the hub before the inner wheel bearing components are assembled. Therefore, installation of the outer wheel bearing requires three tools (besides a driver handle) instead of one. The flat side of QT1801 Cup Installer is used to drive/press the outer cup in until it clears the snap ring groove. The Snap Ring is then installed in the hub groove with snap ring pliers. Next you use a suitable tool to drive/press the cup back against the snap ring. Inner Wheel Bearing and Seal installation is done in the conventional manner.

Tech Note 4: Dana 70 Rear
Dana 70 Heavy Duty (70HD) axles were used in both Single Rear Wheel (SRW) and Dual Rear Wheel (DRW) 1 ton pickups and pickup based cab and chassis applications as an alternative to GM 14 bolt 10.5" rear axles. Conventional Van and Panel Van based models may have Dana 70B, 70U, or 70HD axles depending upon the year, Gross Vehicle Weight (GVW), and chassis model.

Tech Note 5: Rename
In 1994, General Motors sold it's axle division to a group of investors who renamed their new acquisition American Axle Manufacturing (AAM). The AAM 14 Bolt, 10-1/2" Ring Gear full floater rear axle is what used to be called the GM corporate 14 Bolt, 10-1/2" Ring Gear full float rear axle.
