    I have found a corp 14 bolt out of a 78 3/4 ton 4X2 It is at a junk yard and they want 35$ for it if I take it off..Is there somthing to look for when buying a used axel, I dont even know if it will fit my 85 blazer but I found a place that said they can make it fit..for the right price.

    For $35 bucks, it don't matter go get it, but to answer your guestion....Pop the diff cover and look for missing or chipped teeth on the gears, check for uneven wear on the ring gear, leaking seals and bad brake assemblies..leaking slaves worn drums etc...make sure you get all the rear end...e brake cables included...WK

    U-joint and e-brake cables are probably your biggest concerns. Trick joint should not be a problem and a stock cable from one vehicle or the other should hook you up.

    Read my axle swap article, I go over this. The 2 wheel drive axle has lower shock towers on it!

    As far as I know the 2wd axle should bolt right up, it will just have lower shock mounts on them which means you may need longer shocks (If your going to wheel your Blazer, I would get a 4x4 axle for better ground clearance). Another thing to think about, is the pinion angle may be different because the 2wd axle was made for to be connected to a lower tranny, not sure on this, maybe someone here knows.
