What rear differential do I have

[n.shift]

i have a 2001 rwd Eddie Bauer Ford Expedition. 113k miles with ruble sound when accelerating from a stop and turning left or right. No rumble strip sound when going straight. I read where it could be the limited slip differential. My door jam sticker is missing. But I have the toe tag off the differential. Here is a few pictures. Can anyone tell me what rear end is in my rig? Ty in advance

I've not tried this link but I was under the impression you couldn't get the rear diff info from the vin number

Look at the bottom of that page, there are a lot more codes included, start with first 4 letters on your tag,

so this leads me to me next question. when I accelerate from a dead stop and turn left or right, I get a rumble strip sounding noise. If I accelerate from a dead stop and go straight, I get no noise. Sounds like coming from rear diff. but Im not positive. do you guys think this is the LSD noise that people have been curing with change in rear diff fluid and friction modifier?
