Well i'll be,was that a special option or did it just come with it. ??? TGCTD

 

Haulin in Dixie said that all 2nd gen. Manaul trans came with the 80, that's probably what it is, i've got a 5 spd

 

I did not no this ,well live and learn. That's what i love about this site. Learning at cyber-speed ;D

 

Actually it is a hybred, the manuals come with a Dana 80 diff with 70 spindles. Many of the autos have the Dana 70. Mine is a 2500 with the 80, no options, just stock. I have forgottn the site but I was on one and printed out the info that went into great detail on this subject. The 2500 housing has a bit smaller inner bearing than the 3500, everything else is the same. So far the 2500 bearings have performed well, at 126,000 I checked them and they were good enough that I had no reason to put the new bearings in that I had bought. They looked like new, no obvous wear. And I do load over 5000 load on the axle dailey. At stops I check often for heat at the bearings.

 

I don't know about the bearings but the parts house said the seals are the same.<br>What kind of lok-tite do the use on the axle bolts? That's some tuff stuff.

 

Jerry I assume that means you at least disassembled the hub and what did you find that may have caused seal failure. Loose bearing adjustment, bent seal, scarred stub surface- was the color of the oil in the hub resevoir dark with metal particles in it. The seals may be the same but compare the numbers and physical likeness. Loctite is different colors-what color was on the threads of the bolts- parts place will match it up. PK

 

every thing looked good, but there was some rust on the spindle, probably since new. I cleaned up the rust and put it back together and will just keep an eye on it. There are some seals that have a wear ring that slides over the spindle for the seal to ride on, but I doubt there is such a thing for a Dana 80

 

Jerry sounds like you got it back together OK, yes I personally like the seal race system that way the stub never gets a groove. The rust could also be from condensation but as long as it's cleaned up it don't matter no more. Did you discover the reason for the seal failure, brake shoes were OK or how about the axle vent. PK
