I do about 8 axles a week at our shop. We just take a cordless impact and hold the yoke with our hand and pop the pinion nuts off. We do everything from 2012 jk's with 100 miles to 89 cherokees with 300k plus. They all just come right off. Now going back on with a new crush sleeve is a different story. We use a very long ratchet and a big cheater bar with a factory tool on the yoke.
