Shot rear end
Hey what's up guys,
The rear end just went out in my truck and I am having trouble trying to figure out which one it is. If anyone could help it would be appreciated. It is a 78 f-250. It came with a 400 in it but there is a 460 now. I don't know what else the guy swapped before i got it. Thanks.

Can you get the tag code from the differential? It is located on the bolt pattern of the diff cover.
If it's not a swap-out it's a Dana 60. The ratio depends on that tag.
If you can't locate the tag, a good way to find the ratio is to lift the rear and count the rotation of the driveshaft in relation to the axle. If the axle spins 4.1 times to each turn of the pinion, then its a 4.10 ratio and so forth.

When ordering Dana/Spicer Differential Parts provide bill of material number. This number is stamped on your right hand side axle tube. It's a number like 603XX-X, 604XX-X or 605XX-X. With this number you can tell exactly what components the factory used in the assembly of your differential. Plug the bill of material number in Dana's site, information is also provided should you want to change gear ratio.

Look for this number to determine the exact axle on your truck now.
The Dana site mentioned only decodes axle #'s back to 1979 so you may have to post the number here to have someone decode it.
