Re: Rear Axle Identification 2001 Blazer
Even easier way to do it.
Look under the back of the Blazer. The center of the rear end will have one of two things:
At the bottom of the housing, a 7.5" has curved 'fangs' on either side. An 8.5 rear end will have triangles (one side of the triangle flat to the ground, the other straight up and down).
Also, an 8.5 has axle tubes that get wider at the center section, kinda flares larger before they connect to the center.
Vehicles may be subject to change......
