8.8" differential...which is which???
I have a 1988 Bronco that came with an H9 3.55 limited slip differential in the rear. The carrier was blown up, so I am replacing it. The carrier in the truck had what looks like a "Trac-lok" system with the S-spring and all the shims/clutches in it. The one I picked up from a salvage guy looks a lot the same, except that I don't see all the shims/clutches or the S-spring in it. It just has side and spider gears, and a shaft. So, I'm wondering if this is in fact a limited slip diff or just an open diff. Or did the ltd. slip carriers change designs some in the later years, since this diff I got is off a slightly newer pickup. Thanks.

I wouldn't try and get a LS from a junkyard. Usually they start to loose their ability to work properly after time, so baiscally you'd be getting a used weak LS.
A new LS is about $200, and so are some lockers, so you could think about a locker. Not sure what your conditions are for.

My conditions are basically for snow plowing, which I know is a perfect application for a LS diff, but I'll give this $50 fix a try this year. We just moved into the snow belt, and I just got the truck for $500 and will be putting a plow on it in time for winter, so we'll see how it goes. This truck isn't going to see much off road time...that's what my '71 Bronco is for!!
