Gots to have lots of power to break a 40 spline axle....or even a 35....assuming traction is there. Getting rid of the pos track-loc isn't hard to do if you already have 4.10's in there and the Powr-Loc has bearings already on it. If you need to remove old bearings and press on new ones, then you need to have at least some of the proper tools for doing that. A press makes makes things easier. I have a pinion depth tool that helps a lot imo. If I may ask, how did the Trac-Loc get in there? I don't like that design and rather run a cone unit vs one of those. Also having 'setup' bearings makes the job much easier....which are bearings that have a slip fit. Slip fit bearings can be bought or you can hone a good set yourself but honing your own will take some time....and they are not meant to be used as a permanent bearing.You can break most axles if you try hard enough!
Big tyres and a good burnout will get some real grip off the line and a very loose converter will bust them gears, even seen 40 splines broke on a sticky track lol...
Anyways I have a 71 Gtx with a trac-loc Dana.
Folks are saying 400hp in a large car is about your MAX!
So I’m gonna swap it out for a Powr-loc with 4.10’s...
Am I gonna need anything special to do it?
Thanx in advance for John.
