Axle swap / compatibility

63 Views 1 Reply 1 Participant Last post by  Rob1984
So I have a 06 Sierra 1500HD and my rear end has a Slight hum at low speeds like 60km or less.
So I’m wanting to move from my 373 gears to 410s. Wondering if I can swap axles from a 2500hd or if the driveline is different ??
What axles are interchangeable with my axles I have now ??
