Hello and yup this is my 1st post, name is Sean, glad to meet you all. Really need some help...and if any of you are local to Yuma AZ and need help with something I have a full machine shop, and all disciplines of welding available at my house, mention your a forum member and I'll help you out wherever possible. Feel free to IM me.


So here is my problem.
This truck is new to me, had it 3 days, going through doing preventive maintenance and came across a headache which I'm sure one of you will consider simple easyTrying to find which rear differential I have.
2000 f250 super duty 7.3 l 4x4, no axle code on door from what I see.... so please correct me if I'm wrong here, rear axle has sterling 10.5, 377 ratio, no ABS front or rear. I read one tag as E409H which I think is limited slip, but would like confirmation so I know if I need LSD additive. Also it says synthetic 5w140 only...I assume that was supposed to read synthetic 75w140.
Just want to do this right 1st time.




Door sticker



This is one tag



This is the other.

Yes I searched......yes I'm confused

Guess easiest answer will be pop pumpkin and look at it.... funny thing is I feel alone in this situation....I can't be the only one.

Ford. 10.5 ring gear. 3.73 ratio limited slip. 75/140 snyth. you can buy the gear lube with LS additive already in it.

This is assuming that vin goes to that truck and that rear end came with said truck and nobody has replaced anything in it.
