12 bolt posi rebuild

Is it possible and financially feasible to rebuild a 12 bolt that is currently open to a posi or locked rear end?

Just trying to plan how to spend money I don't have just yet

Re: 12 bolt posi rebuild

I planned to do this and found out it will take about $400 doing it yourself or $800 to have it done. So I am thinking of waiting until later for mine.

Re: 12 bolt posi rebuild

when it comes to axles dont go cheap. You dont want to rebuild it again because of inferior junk. You looking at the difference between a couple hundred bucks. A good Eaton pro Posi will run you around 400. new bearings and seals... around 60-80 bucks, new Gear set... 150-200. if you have never set up a GM axle i would not experiment with new stuff. Especially if you dont have the right tools. Pay someone a hundred bucks or so to come over and show you how.
