I have a 2000 F150 4x4. I got stuck a little while back. When i was trying to get out i noticed that only one rear tire was spinning. Making me think that my truck does not have a limited slip rear. Does anyone know how much a locking rear diff. is and which one is a good one how hard it is to install. This would fix the problem too correct?

 

First look at the door code for the rear diff. If it is a letter and a number, it is a limited slip. Example H9. If that is the case, it could be that it does have a problem or as it states is limited slip, but you still can defeat it. If it is 2 numbers, then it is an open diff.

 

Thanks kingfish51. Ill check on it when i am back in the states. I am deployed right now. I just noticed that you live in Mt. Airy I grew up in frederick but am stationed in Louisiana for the Air Force.

 

Glad to hear from a local. Take care and thank you.
