General Description

These trucks use various rear axles. The axles can be identified by ring gear size in inches, by manufacturer (American Axle Manufacturing or Dana) and by the type of axle shaft used (semi-floating or full-floating). AAM axles include the 8 1/2, 8 5/8, 9 1/2, and 10 1/2 inch ring gear axles. Dana supplies an 11 inch ring-gear axle. The locking differential is supplied by Eaton.
