Hey guys got a rear end trying to find out what it actually is. Its on my brothers 2011 F450 dually. I know its 4.30 ratio and thats about it since im not there to check more till I get home. I have him checking number of bolts to hold cover on and number on axle tube per request by randys. Is it a dana and what one? One web site I checked said its a dana S110 drop out but its not a drop out according to my brother. I did a search and all searches point to old tag decoding, and for some reason I cant get into coffee table now(doesnt open) if it even has info on that,cant remember.The tag on my rear end says 4.30 BC34-GC 2010942 3 LS
Anyone have any ideas? LOL to tell you the truth I never even looked up what my truck has yet.

 

what do you want to do with this?

 

the stock rear axle on a dually is a dana 80

 

There is also an axle code on the door cert. B pillar.

 

I need to rebuild it

 

Yes I know, which doesn't tell you anything about rear end other then the code ford gave it. Unless there's a code desirfer sum where that translates this but I havent had any luck.

 

This..............


Its a D80. The D110 is in the F450 (and F550) chassis cabs. The pickups got the D80.

 

This is what I'm thinking also but would like to confirm it. Btw what is the difference of a cab chassis vs pickup, I mean how do u tell? Thank you

 

Did the 450 come with a pickup box on it? On with just the rear portion of frame exposed?
1st example is "PICKUP"
2nd example is "CHASSIS CAB"
Good luck, Don

 

Yes has po up box like normal, so should be Dana 80. But what I don't get is sum sites like Randy's only have Dana S110 listed for F450 and I asked them and they started asking me to look for numbers on the axle tube ect... That's y I got confused.
