Trac-loc rebuild

[RangerJoe]

I've got the carbon fiber clutches soaking in friction modifier now. I have an Explorer 31 spline unit stripped and ready to be rebuilt. I am going to reuse my FRPP 3.73's that are in my car now. When I took the Explorer unit apart, I got to thinking.

Can I take the side gears and spider gears from the 31 spline unit and install them in my 28 spline unit that is in the car? The side gears are what actually have the splines on them. If I could do it this way it would save me from pulling the carrier and having to reset backlash when I put the new carrier in. I've read about a dozen post all over the internet, but get conflicting answers. Are the 31 and 28 spline carriers the same size, with the exception of the side gears?

Thanks in advance!

Well, since you have the parts just sitting there..........................try it and tell us how it works out.

LOL...yeah, I thought about it. I just hate to do it twice, but I may end trial fitting the parts after I get the 28 spline out and see what it looks like. Hopefully someone will chime in with a definite answer.

Try this: remove 28 spline axles (they are coming out anyway) now remove "S" spring from differential, remove side gears and spider gears, slide in 31 spline side gear and see if it fits the original 28 spline carrier. If it does, then mock up the carbon clutch packs and see if they also fit the 28 spline carrier, if they do, you should be good to go, if not, hell you only spent about 10-15 min to find out and you have to take the 28 spline carrier out anyway.

ive asked before and told it wont work... but give it a shot...

lemme add they said they had never tried it but thought that the 31 and 28 spline center sections were different. other then just the spider gears

I read somewhere that the cross pins were different sizes, but I guess I won't know until I try. Hopefully I'll get to this in a week or so. I'll let everyone know for sure.

Thanks,
