    • The 8.5″ axle was used on vehicles up to 1999. The 8.6″ was used on vehicles 1999 and up. Since 1999 was the transition year, some vehicles received the 8.5″ while others received the 8.6″. The easiest way to tell the difference is by looking at the brakes. All 8.6″ axles have disc brakes and 8.5″ have drums.
