Anybody running 4.56 gears in a somewhat stock setup. I'm considering swapping my gear from the stocker to a yukon 4.56. My rearend leaks now and I'm sick on the puddle in the garage so I have to tear into any way. Is there a way to adjust the speedo? I know there are speedo gears for 4.10's but I haven't seen anything for 4.56. Second, what should a shop charge for a gear install including bearing replacement, just the labor if I bring all of the parts? What is needed to repair the limited slip?
