The 8.8 with 31 splines. The exploders had 28 splines, so make sure you don't get one of those.

If you do....you could probly swap the axles and chunk out to the heavier splines just so you can keep the disc brakes.

Right, all rear bronco axles have 31 spline axles.



"single track"
.... open diff.

Your saying you want to find a axle with a limited slip to swap in...?

IF so, just look at the axle tag, if it has 3L55 it has a limited slip, but the factory limited slips weren't the greatest, and just got worst over time. A locker would be easier, better traction than a worn out limited slip too.

Better traction than ANY factory limited slip (trac loc)

limited slips work better in the snow for a daily driver.

This is always one thing I never think about when answering questions....

Mostly do to the fact that I haven't seen snow in about 10 years!

What happens when you get stuck, one tire has traction,the other one doesn't. The limited slip will allow all of the slip in the world because it can't overcome the traction. If this was a "real" limited slip, instead of a worn out JY unit, this might be a different story. I personally will not bother with a trac loc on the rear end, except in a street vehicle, driven on clean, dry pavement.

you dont live in the snow do you? so how can you compare? i live were it snows up to 3' at any given time during the winter. if you have a locker it is very easy to spin yourself around in an intersection or anytime you turn a sharp corner. the limited slips alow you to drive and still maintain traction. of course if the LS is worn it wont work as well but that can be fixed. In deep snow a locker can make it even harder to go strait as well. I guess you almost have to experience it to understand. no biggie

I lived in northern Canada for ten years. I can tell you I prefer a locker than a limited slip. (I had both) When driving in snow you have to adapt in either case. But, you are wayyyyyy less likly to get stuck if you have lockers. If your skard, get a swichable locker.

Its a good thing you know SOOOOO much about me. I stand by my personal preference of lockers(and spools) vs. limited slip. If you were to use your truck for more than getting groceries and posing at the mall, you would realize that a limited slip is VERY limited on its capabilities of being usefull, and being marginally better than an open diff. I would trade off any extra difficulty in control and steering for the reliability of having both wheels locked when things get ugly.

If I was to use what I percieve in your post to be your sense of logic and reasoning, I would assume that you don't have the ability or patience to adapt to driving with a locker, or learn how to SLOW DOWN and not be a menace on the road, but like you said, no biggie.

my bronco is built to go anyware i point it. both diffs are open to accept a set of lockers when money permits but i will say in the meant time i havent needed them YET. Dont get personal I wasnt. I assumed that you being from sunny socal rarely made it up to the snow.
My wife has to sometimes drive my rig in the winter time and having a locker in the rear is going to require some major learning on her part to get around. For the folks that use there bronco more as a DD a limited slip would make more sense in winter time condtions. less tire wear and far more predictable. lockers on a short wheelbase like the bronco can pose a safty risk in the snow and ice while the same setup in a truck i far easier to control which i used to own a 73 f250 hiboy with front/rear detroit which was fun and had no powersteering either.
Mac_91 didnt give any info on his driving style or use.

Kem is right about that. Limited is alot more stable speaking from experience with a limited rear end in my 79 and the trac lock in my 95. The Trac loc will come in handy when you get down in some deep snow or if you are in a ditch for whatever reason. Got my lifted 79 stuck when i was half way in the ditch and half way in the road. The two drivers side tires where only spinning and it happened to be an icy road. I had swampers and a 460 so after a while i would spin up and break the ice. If it had a trac loc or a locker i would have got out no problem becuase my other side was mud. I cant wait to see what this 95 with the trac loc is going to do this winter saying last year i was driving a 2wd F-150 Also if your worrying about spinning around couldnt u just put it in four wheel drive? That should add some stability.
