Rear Diff fluid?

[strokin07]

Last week I purchased a 2008 F250 KR.

1. How do I know if it is a limited slip?
2. What diff fluid is preferred?

On another note, the steering wheel has about 3-4" of play in it. It's lifted 6" with 35's. Would a new gear box solve this or could it be something else?

Thanks!

Ok. So I did some searching and determined it is a 3.73 LS. So with that being said, What fluid do I use and is it possible for the LS to go bad because I spun a single tire the other day pulling out of my neighborhood?

Seems possible to me. A limited slip is just that, it limits the slip.

I believe some fluids have the LS treatment in them already, I've used Royal Purple before.

the play in your wheel, I would check the pitman arm to make sure its tight.

Hey, thanks guys. I will be doing that fluid change asap. Also I checked the pitman arm for play with the aid of a friend and it is indeed loose. So now I suppose I will either tighten it assuming its not or put a washer or spacer to make it tight.

OK thanks. I suppose I will need to take it somewhere.
