Rearend code??????

[jimbobb2]

The rearend is going out of my truck (2000 F-250 4x4 7.3PSD) and everyone is asking the axle code. The tag is gone and I have no idea what it is beyond a 3.73 gear with a posi-type locker. Any ideas on what code I should be looking for?

I think if you look at the data tag on the door post, where it says axle, there should be a # or set of letters.

[jimbobb2]

The door post just say 3 letters, but everyone is looking for a number and letter combo.

Is there any real difference in a gasser rear vs. a stroke?

[ipz2222]

probally just the ratio. Do you not have a tag on the rear end cover??

Go to the dealer and get the as built data.

No, the cover had been replaced before I bought the truck. When I have called some of the wrecking yeards, they say that there are 7 different codes for 3.73 rears in 2000.

Had not thought of that. I will see if they can help. I know that it is not drivable at this point. The housing is worn where the bearing had been spinning on it. I put a set of bearings in hoping that I could prolong the death, but it is still making the rumbling sound. I am sure it is just a short time from breaking the housing.
