year of your truck?
on my 08 its on the tag on the door column between the front and rear doors.. mine is 4N (4.10 limited slip) last row, right, under 'Axle' Sam |
Yes you have two tags on the rear diff cover, one tells you type of fluid if its LS it should say 75-140 synthect ,and the other one has these numbers v423f on top of tag then L73 10 5 3009 and mine has the LS so maybe yours match
|
wulfman as for what i can see one tag i can see v425f but it could be a 3 and then the other tag i can just see synthetic
|
Lift one tire, in neutral, and try and turn the tire. A worn LS will still fight you a bit.
|
i read the tag and if says v425 b not f sorry. and okay i will try that when i get the chance. thanks
|
You can also do a burn out and see if it lays down two black assss mark. Mine will
|
i remember when my 04 did a posi instead of a peg leg.... the good ol days

Anyone know which rear axle I have by these PICS? I can't see another sticker on it. Inside the driver's door it say D1 under AXEL. I need to find out which oil it takes, and Ford can't give me the Build List for a few days. Thx!

What year and model of your truck, and which factory options?

What rear end ratio is in my Ford , do I have positraction? - Drivetrain.com |
It is easier just to read your door sticker, under AXLE. Look closer, D1 is not a choice. 3L maybe, or 41?
AXLE CODES: 37- 3.73 3L- 3.73 LS 41- 4.10 4N- 4.10 LS 43- 4.30 4L- 4.30 LS 48- 4.88 8L- 4.88 LS 53- 5.38 5L- 5.38 LS |
Sorry for the hijack of the thread but is it a good thing to have LS in a truck?
What are the advantages/disadvantages? Thanks |

Lest say you get on some slick stuff on one side if you have a LS then the other side would get some traction if you did not then you would just sit there and spin one wheel. Sean :-drink |
To be a little more clear:
A differential's job is to allow the axle shafts (and thus the wheels and tires attached) to turn at different rates. That's because when you turn a corner or go anything other than absolutely straight, the outside tire needs to turn a little faster to cover a little more ground than the inside tire, just like the outside of a record is covering more ground per revolution than the inside, right? Well, one side effect is that the power ends up getting transferred to the wheel that's traveling the fastest, and unfortunately that sometimes means the one with the least traction. Let's say you're on the side of the road in the rain, out in the country somewhere. Your driver's side tire is up on pavement, your passenger side tire is in the slick and sloppy mud. When you put it in gear and hit the gas, the tire in the slick mud is going to spin and spin while the tire on the pavement does nothing, because the tire with almost no traction is the one getting all the torque. I'm sure this has happened to all of us or at least seen it happen to others. That's why they invented various "traction aids" such as a limited-slip differential, a locking differential, and various iterations on that theme. The LSD in particular means that due to one of several different mechanisms (usually spring-loaded clutch plates), when one tire ends up spinning too fast compared to the other, the clutch plates are forced together, transferring some of the power to the wheel that otherwise wasn't doing anything because it had all the grip. So in your situation with one tire on pavement and one in the mud, the tire on the pavement ends up getting power now, too, and it is able to move you forward and out of the rut you've dug for yourself and hopefully up onto the road and home. |
