Junk yard differential
Mine is an 8.8 open, 3.55. What limited slip or posi will bolt up to my stock, like from an Explorer or something. This is a hunt for something cheap, and i know the local junk yard has cheap prices.

I believe as long as the differential comes out of a 8.8 it will work. So That means, Bronco, F150, Explorer, and Rangers too. However I believe to get a trac-lock differential it will have to come out of a 4x4, they were most common in the 4x4.

The bronco should have trac-lock rear, cuz very few broncos were 2wd.
NOT ALWAYS: but normally 4x4 has the trac-lock (limited slip) and 2wd has open differential.
Idk about the explorer, but on the F150 or Bronco you can look on the sticker in the door and it will have a axle code. That code tells you weather it has a open or trac-lock differential.

There is a rolled Bronco II that's about the same year as my F150. I'll look and see about the rear Diff. The stickers are gone, of course, so that's part of my questions here. I can get the guy to bring the forklift and put that thing in the air and then rotate the wheels and see if they both turn the same direction, is this the right thinking SC Rebel ?

That should work in theory. However if the clutches are wore out it will still act like a open differential.
Also I would recommend standing under the bronco 2; and turning one tire with one hand, and place the other hand on the other tire and hold it in place. So that you can feel how easy it is to keep the other tire from moving, or how hard.

There were two different carriers for the 8.8. One has 28 splines and is found in cars and a lot of Rangers. You will need the 31 spline version to fit in a full-size truck. The limited slip might be more common in 4x4 trucks, but as with any option, it's going to be hit and miss at the junkyard. Limited slip axles usually have a letter in the axle code on the door sticker, H9 or something similar. Open axles will have only numbers, like 19. My gut feeling is that the Bronco II has 28 spline axles, but I don't know that for sure.

Make sure the replacement axle is the same width as the one you are replacing. Also, if you have 4wd you MUST use the same ratio as you currently have, otherwise you will cause severe damage to the drivetrain. Some people have used the Powertrax no-slip and Lock-rite with hit or miss results. No extensive teardown of the differential is required.

Are you looking to swap the carrier or the whole axle. If you just want the whole axle, look under 2 and 4wd F150's and Bronco's 87-96. They'll have the 8.8 rear with the ABS setup.
First, look at the door sticker for "H9" axle. Then look under the truck at the axle for the metal tag that's attached with one of the cover bolts. It should say something like 3L55 8.8. There will be other numbers too but those are the important ones. The 3L is close to the bolt hole and sometimes the 3 isn't visible. 99% had either the 3.08 or 3.55 ratios so if it just says L55 it's safe to assume it's a 3.55. Especially if the door says "H9".
The one I got for my 86 was under a 2wd 89 F150. All the 4wd trucks I've had have been open. So I don't think there's any truth to 4x4's getting lockers.

O.K. the Bronco II won't work, as it's the same as Ranger. The 31 spline is more like it. Thanks for that ! Also the tag was a good idea. There's a full size Bronco there, but it might be an automatic. There are a couple more candidates there, and at least one is again, an automatic.

Know what you mean. I have a Ranger that has a 9" Ford Tru-lock with 11" brakes. Bought it from Currie Enterprises in Anaheim, Ca. It was over $3,000. I don't want to spend that kind of $ on the F150
