Are you trying to shop for parts to buy or figure out what you have?????

If you're trying to decipher what's in your axle find the BOM on the rear of the right side tube (ex format; xxxxxx-x) and plug it in to the dana site (www2.dana.com).

Between the truck application and the fact it's a D70HD you should be able to shop for any parts out there.
