Need Some help

I was looking at a 90 K5 and it runs great but then I checked the 4 wheel drive on pavement, I know not good but any ways. It has auto hubs on it but when I locked it in it was fine in a straight line but when I turned it started binding and popping. What do you think? Hubs or possibly mismatched gears because the K5 had a 12 bolt in the rear but I would of thought the gear difference if there is any would show up driving straight. What do you think.

That is what it should do on dry pavement. The binding and pooping is the front tires gripping the pavement. Never use 4WD unless you are on ground that can give (i.e. dirt, mud, snow, rocks, etc.). You can seriously damage the drivetrain by doing that on dry pavement. It sounds like it's working just fine.

Also, if the front/rear gears were mismatched, it something would have gone BOOM way before you tried to turn a corner.
