Well it finnaly happened, was out wheeling yesterday and heard a huge pop and then grinding sounds. It was kinda my fault though I was hammering it way to hard and hit a ditch sideways. I think it locked up at about 4000rpms and just couldent handle it. I Popped the cover today and there are metal shavings at the bottom of the diff and my ring gear has some gouges in it. My question is should I take out the gov-lok and replace it with a detroit or lockrite and run the gears how they are or should I just replace the whole axle with a new 14 bolt. I can get one from a 1978 K20 with 4:10's and another gov-lok for $200. Will this bolt right into my 1984 K20? Chips in Gears, are they ok?
