Posi ???
How can I tell if my 2004 F250 SD 6.0 CC has a posi rear end in it? It has been laying one wheel peel's but i was told if you put the additive in your rear diff it can start working.
Is there a vin digit i can look at or something or will it say somewhere?
Thank you,
Bob

Go to the Super Duty tech Folder here:

In post #3 and post #9 are the axle codes. The codes in #3 appear to be for the pre '05 trucks. Check you VIN label on the door or door frame of your truck. Down near the lower right corner of the decal, there should be a box that says "axle" and it will have a code in it. Compare that code to the codes in the Tech folder and you should be able to find out what yours has.
