I have a pre 1977 3/4 ton dana 44 (H.D.?) as my front axle while running 35's. I was wondering if there is really any difference between the pre '77 and after '77 44's? I know the brakes and bearings are different (I used to think it was an '78, oops) but is one stronger than the other. I had a guy at the local 4x4 shop go on and on about how the older dana that I had was much stronger and almost as good as a 60! I always thought a 44 was a 44, was a 44,was a 44, etc. Is he on crack, or is there really that big of a difference.
