Limited Slip rear diff??

My dad has a 2000 Ranger 4x4 ext. cab and we're going to change the rear diff fluid. He went to our local Ford dealer but he said they had a hard time determining what kind of diff (LS or not) is on his Ranger based on the VIN number. He said after a few minutes of browsing the computer the parts guy just studdered and said he's 'pretty sure' it's NOT a LS diff.

So I want to find out for sure. How can I determine if the rear diff is LS or not? Did 2000 4x4 rangers even come with an LS diff? Thanks

Yeah, you could get an lsd in a ranger 4x4 or 2wd. The difference is that the lsd needs a frction modifier. There should be a little tag on one of the rear diff bolts with the info on it.

there is ID plate bolted on. Just clean it and read it carefully.

It will read 3L55 for an LS diff, and 3 55 for an open diff. You can also look for the axle code on the drivers door or door pillar.

my understanding was if you jack up the back axle and rotate 1 tire and the other tire rotates in the opposite direction it is not LS. Anybody else heard that?

Axle code is 97 so it's an open diff. Thanks everyone.
