77-79 4X4 CrewCabs
Sad, but no. I pulled a D-44 out of a '78 F-250 Crew Cab and it had only a 7700# GVW. Crew Cab did not automaticly get you a D-60. The more I hear it was the Snow Plow option on the F-250's that got the D-60 as well as all F-350's.

Yea mine has a D44 front and D60 rear. However, there are different axle weight ratings for the D44 I think. Mine is a 5400# axle. I think there are D44 axles with less weight ratings. Correct me if I'm wrong.

There are two front axle ratings for the D44, at least in the earlier years. On the lighter duty version (3300#), the steering knuckle is about 4.5" in diameter. The "heavier duty" version has a much larger steering knuckle, perhaps 6-7" in diameter? I haven't seen one for awhile, so I'm not exactly sure of the size.
I have heard that they are otherwise very similar, so little is gained by the heavier designation.
