When I first got my 46 2 ton going I split the pancake at the diff.and shifted the diff.with a vise grip a few times to loosen it up. Then hooked up 3/8 vacuum lines to the factory switch on the dash. After feeding wd-40 into the switch (with the vacuum pulling it in)it stopped leaking. I use it all the time to down shift for going around corners. The diff. will stay in what ever gear you leave it in,there's no spring pressure or anything ether way. But if you leave it in low you'll go really slow!
