    It turns out the pinion bearing on my 94 2wd 1/2 ton is going (gone) and I need to replace it. Rather than have a new gearset installed (don't know how long I'm gonna keep the truck) I was thinking of swapping one of the plentiful 10 bolts available into it. SO my question is - what have I got in a 94 GMC 1500 SLE 2wd? Obviously I have 5 bolt rims, but can I swap my shafts into a 4wd housing? Are the spline counts the same? What do I need to look for? (And if anyone has a 2wd 10 bolt with 3.73's that's a direct swap, please let me know)

    I've done this on trucks from the 70' and 80's. The axles swap out great. Dont know about the newer ones. I would think that they would. It would be more expensive to build more parts instead of just swaping axles at the factory.

    I'm going to agree with Sandman on this one too.

    Just to make sure, measure it out. Wheel flange to wheel flange and spring pearch to spring pearch.
     
  4. correct me if im wrong, but i believe the 2wd rear axels are a little bit narrower than the 4x4 ten bolts.

    Checked it out on some auto parts sight and yeah, the axles for 2wd and 4wd trucks are different lengths. That said, anyone know where I can look for a complete 2wd rear axle?
