Re: K10 Dana 44 v. K20 Dana 44
This is what I've been told, I have yet to experience one myself. I figure if a Jeep can bend a Dana 44 my 4600lb truck can do the same.
I was told that on a true Dana 44 HD they had external hubs, a different spindle nut, and a larger inner wheel bearing. They also had 1/2" thick axle tubes. They quit making them in 76.
The only thing everyone has told me that is the same are the axle tube thickness and when they went out of production.
