is it the dana 80 that has 35 spline axles? i tried to search but it erased 80 out of the search since it was less than 3 letters..

 

mine is 35 spline in my 97.

 

hmm i wonder if they changed any in those few years i replaced an axle shaft a few years back when i snapped the cap off the shaft but never did count them just went to a junker and he had one for a 2000 already

 

the 80's are all the same 94-02 that is if it's still stock. I know 37 spline is an upgrade unit for them

 

my experince is 35 on dodge and 37 on f450. I tried to swap a dodge rp and carrier in a ford it all works except axles.

 

ok then which is better and whats the difference?

not to educated with this whol suspension and locker stuff sorry guys

 

I have a 2000 dodge 3500 dually with a dana limitd slip rear end. When I back up it behaves as if it is slipping intermittently. What is the prognosis for failure & how soon. I do not have the special lubricant additive that is added along with the regular sunthetic gear lube. If it is trashed, then is it possible to changer it for a standard 3rd member, non-limited slip differential? I have seldom pulled any heavy weight behind.

 

powertrax makes decient parts but personally putting that much power through them isnt a good idea.. ive broke two of the lock rites in my dana 60 in the front of my 84 with only a mild bigblock and 37's....id say arb or detroit locker all the way

 

i just have stock 31s so not that much tire to turn and i only plan on makeing 500 -600 hp at the most (most)

 

more than likely it will hold just fine but im just givin you my .02 cents good luck with the install
