Dana Axel Identification

I have searched but can't find a decoder for the rear end on my 2002 F-350. The tag on the differential has two lines
Line 1: 4.10 (there's an upside down triangle here) 2C34 UB
Line 2: 606775-5 LS

I have to buy a seal and bearings but there are questions being asked that I don't answers to.

If I'm not mistaken, Ford started putting the Sterling 10.5 full floater rear axle in their F250 and SRW F350 in 1999.

Go to this webiste and enter your VIN number: FordEtis home page

This will show you everything you should ever need to know about the truck.

Russell is correct. It will be a Sterling 10.5". The search ill tell you the axle ratio and then if you expand more info, you'll see if it is limited slip.

You can also look up the axle code from your door sticker. That should tell you the same thing.

I assume it is a Dana because of the differential case cover.

My bad, missed that it was a dually.

I believe that is a Dana 80.

That would be a limited slip Dana 80.

What questions are you being asked that is giving you a hard time?

That was it. I couldn't find anything that told me that. I have done a lot of research since my first post. I just decided it must be a Dana 80. The tag had LS on it so I assumed it was Limited Slip. According to one web site it has an 11.25" ring gear based on the 2C34 UB. Don't know if I'll need that info.

I get a low frequency growl when driving. I subscribe to the ALLDatadiy manual and all the troubleshooting suggests that it is low on lube as a starting point. I took it to the dealer and asked for a diagnosis. They said it had a leaking right shaft seal and bad bearing. I don't see any evidence. When they quoted over $600 in labor just to see if that was the real problem I told them I would take over. I just hate laying on the driveway anymore. But I can't bend over without soap either. Any way. I almost have the shaft out and I will inspect it, the bearing and the seal and see what I see. If there is damage to the gear on the end of the shaft I guess I'll bust open the differential and see what I see there.

I think I am getting tired of mechanicing. It's probably because it is 9,000 degrees outside. Oh well, onward and upward.

Thanks for your help.

A few things before the big work should begin...

how many miles on this? How many miles since you have owned it?
Have you any knowledge the last time the rear diff fluid was changed?

The low growl you speak of ...are you 100 percent the rear brakes are all working proper and its components? Yes they can cause a growl for sure.

Can you get the rear off the ground and have someone run it with the rear wheels turning under the vehicle's power of course while you listen around different areas. Noises on these big machines have a tendency to radiate to different areas which becomes critical if you can get up close and personal with the area.

Good luck.
