Open rear end, really?

Hey Guys,

I know there's a very similiar thread going on right now, but, how do I tell what axle I have? I just found out I need a Tru-Track BAD! Jegs doesn't list it for my 09 SD by truck model. Hopefully I can find one specific for the axle. It looks bigger than a D60, might just be me though. The dealer want's $1600 + to install the factory LS unit. I must admit, I was shocked two days ago when we finially got some snow here in mid Michigan to find out they'd put 1 wheel drive in something with that much weight on the front axle.

Thanks, Jim

Most front axles are open, but the tru trac might bother your steering by always being locked. I would get a trac lock.

I want a tru trac but my buddies talked me out of it.

I'm actually talking about the rear axle. I found the Tru-trak application guide, now I just need to identify what axle I have. Any help decoding the tag would be great. Like I said, this 1 wheel drive stuff isn't gonna cut it Michigan winter!

thanks, Jim
