Default 2.3 axle swap questions

New guy here, although I've been lurking for almost a year now, looking for a few answers before I start the axle swap.

I have a 2002 2.3L 4cyl 2wd 5spd, current axle code is 86, which is an open 7.5 with 3.73 gears. I drive almost exclusively on the hwy, and am not all that impressed with the open rear differential with my lovely Canadian winters. Looking to swap to a limited slip rear diff. I have no concerns about the work involved, but have no idea what's going to fit.

I'm going to be looking for a used rear end (with drum brakes, don't want the pain of swapping to disc), with as straight a swap as possible. Likely doing the junkyard dive, and not looking for anything fancy.

What should I be looking for? year/model, ranger/explorer, does it matter if the doner is 2wd or 4wd, auto or std(mine is std).

I'm guessing I'm looking for a F4, F5, or F6 axle code........did I just answer my own question? Or should I be real concerned about gearing? Or is the 8.8 an easy swap option?

Thanks in advance, this site is awesome!
2002 2.3L 4cyl. reg cab 5spd. Pretty much stock I'm sorry, I'll try to change that.

Default Re: 2.3 axle swap questions

I would find an explorer with a 3.55 and posi, it is easier to do the disc MC swap, etc. than to find pickup axle with 3.55 posi in my not-so humble opinion!

Try to find rear in same year as yours or as close as possible and use 2wd axle as 4 wd too wide.
