Okay, I have read all of the threads , I think, pertaining to the 7700 payload package on the 2003 F 150 4x4 XLT.
Will someone please tell me if all 7700 trucks have the 10.25 Sterling Vistion rear axle with 3.73 and limited slip or posit-traction, or are those two the same?
The door tag on mine reads that it's a 26 which is a non LS 3.73. Cant be. This axle is built like a tank.

 

Limited slip is an option, even on the 7700.
And yes, it is a 10.25 axle.

 

I guess then i'll have to slide under there and look for the axle tag. Should have done it yesterday when it was up on the lift at the garage getting new tires, but I forgot. I just bought it. Thanks for the reply.

 

 

What is this?

 

I think he meant to post that in a different thread.

 

Ahh. Okay, thought it was something like that. Being an old guy i'm not always sure about this stuff, could be a secret image that means i'm a nut or something. kids....lol.

 

XLT's have an open dif unless special ordered and the XL and base came with limited slip rear ends this is what ford told me when I asked about it when my truck was in having service work done on the rear end
