    Guys!! I'm so excited. I just came from a junkyard and they just received an old suburban with what appears to be a front D60 and a 14bolt!! The guy just wants the equivalent in my local currency of US$500 for BOTH axles. Can you believe this?[​IMG]

    Now for my question. How do I tell it's really a D60? The only thing I noticed is the thick hubs sticking out of the front wheels. While my 10 bolt are about 3.5" in diameter, those were almost 5". Is this a good sign? BTW it had Spicer hubs which looked very tough.

    What else should I look to make sure its really a D60? Thanks!!

    Check the steering arm on the drivers side...is it held on with 3 studs? If it is then it is a D44 or 10 bolt. The D60 uses king pins instead of ball joints and the steering arm is held with 4 bolts.
    I'd guess it was a 3/4 ton Sub and it's a D44, but you never know what someone may have swapped in. Good luck!

    Thanks for that info. I think we're talking about a D44 then. Is this still good? or should I pass on these? From what I've learned, a D44 is practically the same as a 10Bolt, right? Would you go with these axles with a 454?

    You can build a D44 to put up with some major wheeling. Plus you would have the 8 lug front and rear. But a D44 is not as strong as a D60. If you are going to run a tire bigger than a 33" I would upgrade to chro-mo shafts and CTM U-joints to handle the torque of the big block, maybe get a stronger carrier too like a detroit

    Juan,
    An 8 lug 44 will be fine. GM put a lot of 454's in 3/4 ton trucks, and from the way you have always described your wheelin habits I dont see where you would need a D-60. By the way if the Burb is stock it will be a D-44 or 10 bolt they never built a 1 ton burb so a D-60 was never offerd in the Burb's.
