Yeah it would be nice. But the locker is completely transparent in 2wd, even with the axles always turning. As long as no torque is being applied you can't feel anything, just hear a little clicking when turning sharp at slow speeds.

The word "posi" is old talk. I believe there was a limited slip called posi back in the day.

Posi is still old car talk. Its a nickname for limited slip. It always was. Some people can't understand limited slip so they came up with posi traction.

OK, guys I am old, old enough to say you are all kids, (no critism intended, I were your age once too), I started wrenching with my dad at age 6. He was a mechanic of the day, (ERA, he stared working on gas powered vehicles in 1920 or so and did that until 1965, I started in 1954 or so and only did it as shade tree from then until now).
What the definition of a posi was up until I got outa the milirary and probably for a period of time after that, was both rear wheels locked together. (zero slippage in the diff)
I had a 77 Chev 4x4 that had a full posi (spool) in the rear and a LS in the front. You might want this for rock crawling or going places you really shouldn't have gone, (I did that a lot!) but for DD it was and is not the ideal setup.
Posi meaning to me, put one tire on pavement and the other in the gravel, nail the throttle, if it left a black mark or tire smoke on the pavement, and spit gravel at the same time it was posi. Mostly it would just jump forward and the scratch in the gravel was none existent. It also had the habit of trying to push the front end toward the gravel.
Now I haven't done that in a lot of years, but I believe it still holds true.
One of you guys who has a lot of power and some time can give this a try.
It has been my observation that a LS will spit gravel for a couple seconds before the clutches lock up, but then who knows, maybe the ones we were using weren't set up right and didn't have enough preload against the clutches.
Anyway, a posi is locked all the time and makes the front end travel in a straight line, (the old Bel Aire I had for dragging had a posi, SPOOL) it wears the front tires out fast and has zero slippage in the differential. A LS has slippage in the differential (as the name, "limited slip" implies), by way of the clutches, which makes them much more friendly for everyday use, and they don't wear the front tires and front end parts out near as fast.
I really hope this clears up the whole thing, I am talking about what went on in my era, you are talking present day.
My 02 Ranger is LS, as is the 92 Explore I picked up yesterday to make my B2 run again. But LS is not a spool, which is positive traction, it has NO slippage in the diff, LS has slippage to make it work for everyday use, posi in my terms, is not for everyday.

ok well in the "car dictionary"... posi is simply a LS nothing more than a name, not a different type of diff. just to be clear

I figured you were referring to something older, it is different terminology. Obviously you know it is referred to as a spool now. For years and years a posi or posi-traction has been a nickname for a clutch based limited slip.

Yup.

Can't teach an old dog new tricks... or new names apparently.

Posi=Limited Slip=Positive Traction

All the same.

Current set up in my truck
AG 542080-PRO - AUBURN,AUBURN GEAR,LIMITED SLIP,PRO,POSI,POSITRACTION,DIFFERENTIAL - Auburn Gear Pro Series Positraction for Ford 8.8 with 28 spline axles. The Auburn Gear limited slip uses a long-proven cone design to provide traction for performanc rear
Dont have the link for my front Bought through work. But it is also auburn. And took some work to make it work.

Now my question was asking whos done it, not talking me out of it or saying I dont knwo **** when Im sure I know alot more then half the people in this tread and have been around mechanics for quite some time now. Maybe if you knew my history in the offroad communtity and the work I have done and do everyday, You possibly wouldnt be bashing me.

Oh and thank you Clem you are 100% correct, that was how my pathfinder was after the sas and d44's.

If you've got an LS in an SLA ranger front diff, post up.....there are a TON of guys who would be interested in how it was done. We're all looking to share info......

x2.
Pull your head out of your @ss dude. Everyone's pissy attitude here is getting really f'ing old.
You got input from people who have had aussie lockers in front, and one told you that there was plenty of breakage with that alone. We were giving suggestions and opinions, not intending to bash anyone. A lot of people gave you suggestions that would more than likely yield better results and be more reliable.
I have heard a ton of people say "limited slip" when they really mean open, and using limited slip and posi in the same sentence is redundant by today's use of the words (therefor it sounds like you are not correctly describing what setup you have). And I have not heard of a single person installing any limited slip in the front of an IFS ranger, other than the 2 or 3 test units that torsen produced.

Like I said before, if you have good info to share about the limited slip up front, please do as plenty of people would love a limited slip up front.

In the meantime, no I don't know of anyone who has welded the front diff of an IFS ranger, and my opinion is you would regret it.

I tried to get a hold of a friend that lives up north to ask what he used in his 80's, whatever year, B2 that's got diffs out of an Expo. No luck yet, probably out fishing or chasing some skirt.
I seem to remember the carrier came out of a Jeep or a Scout, something along those lines. It was a front diff that had a clutch lockup LS. His biggest problem was finding the ring and pinion to match the rear end ratio, but like my 77 Chevy, you can get into places you don't want to be or shouldn't have gone to in the first place.

ARB used to make an air locker for the front and rear of RBV's, but somebody said they quit making them, I have no idea. The ones I have seen in operation were pretty good, but a Detroit is so much better. IMHO

I am sure there is something out there that will work if you really think you need it, it is just a matter of finding the right piece and finding out if it will work or not. When your trying to do something that someone says can't be done, it is a whole lot more enjoyable when you do make it work.

As for teaching an old dog new tricks, this old dog has a saying he lives by, "If a day passes that I don't learn something new, that day was wasted." I haven't wasted very many days, can you say the same with all honesty?

I just had a thought, (I know, that's dangerous), has anybody got a front diff carrier sitting around? What we need, is to know what the dimensions are for the outside of the carrier where the rind mounts, the outside diameter of the bearing races, and the spread, (length) of the carrier from outside to outside of the bearings. I think the distance from the center of the carrier to the center of the pinion drive teeth would also be very helpful. Having these dimensions will be valuable to getting some company started in the direction we want them to go.

Also, while I am on this kick and don't know the answer for sure, is the front carrier in an older Expo the same as the front carrier in say, an 04 ranger? Or did they change all the dimensions when they changed to this type they have now? You can come on and tell me what this new style diff is, I will learn and you can crow about the old man not knowing, I don't care. I just want to figure out a way for those who want this to have it, then we will see how many talk about the brown stain they have in their drivers seat.

As for my vocabulary, I may still be living back in the 60's threw the 90's, but red is still red and posi still means it is a spool, not an LS.

No. The old TTB (twin traction beam) diff was a Dana 35. The new SLA (short long arm) Ranger/Explorer is a "hybrid" dana 35. The gears are D35, but the carrier IS NOT the same size. I beleive it is a tad smaller.

There are a few prototype LS carriers floating around, but nothing on the market or known. RangerRick over on offroad rangers worked on those things, he did at one time have one of the prototypes, but that was years ago. That site has not even been up in a long time.

That's why I'm trying to get this guy to post up what he has, b/c if he does have an SLA LS carrier it will be quite interesting.....if not, he just blew a whole lot of smoke up people's butts pouting/bragging like that in the last post.......

As for the "posi", I've always known that as GMs moniker for limited slip, but whatever

My dad worked on pretty much every car/truck you could imagine from the early 60's till 95... my grandpa from the early 40's till sometime in the 80's... neither of them ever called a posi a spool... posi was LS... spool was a locker...

but then again you're from the PNW.... so I'll excuse it...

Exactly. The carrier is not the same size.
There has been a lot of time and effort trying to get a manufacturer to build a limited slip for the front end, but no one has. Torsen made a few units, RangerRick, DesertSpive (this truck is the project range-runner in a mag), and I think one more. It never went into production despite tons of emails.

Clem the front differentials are the same for the following;
98-current Ranger
95-01 Explorer (although I think 95-96 had some extra vacuum plug or something on them)
01-05 Explorer Sport Trac
Also some newer Explorer Sport models, I don't remember how long they carried them up.
