I have 31 spline axles & mini spool. Got a deal on 28 spline third member. How hard would it be to convert the 28 spline gears to 31? It has a full spool.

You'll either have to replace your axles or get rid of the full spool and replace it with a 28 spline setup. The gears can be run on both setups, it's the internals for the axles that lock you down to what you can do with it. Hope that helps.

You just need to ge a 31 spline full spool and swap it out

Thanks, I was hoping that was it. Didn't know if the side bearings were different from 28 to 31. Guess not.

Nope, side bearings are the same. Just swap spools.

Side bearings are not always the same..depends on casting and years. there are several different sizes out there.

JUST LET YOUR LOCAL SPEED SHOP TAKE CARE OF IT.

Just buy a set of 28 spline axels then you can run either center section.That's what we did as we run several dif,gears and when you buy used you don't always find the right gear with the right spline.I'm thinking someone should make a set of axels with 28 on one end and 31 on the other,then make drive plates 28&31 then you would only need one set of axels and just switch drive plates
