For a street rig, yes. It will be fine. For ANY kind of wheeling, no. As Hossbaby50 said, if, by some amazing grace of a higher power, you don't break the internals, the balljoints will suffer. The wheel bearings would also take a beating as well. The brakes I'm not too worried about as they share the same diameter as a D60. However, the calipers on a D60 are larger and will provide more stopping force.
But, this all depends on what kind of truck you are running, how much it weighs, which 44" tires you plan to run, AND how heavy your right foot is. I have seen them run on a 3/4 ton axle and have seen it take far more abuse than I think it should, but in no way do I condone it on a wheeler.
