How can I tell the dana 30 front end from the dana 44???

[Bronco Ben]

Is there an easy way to determine which dana 30/44 that I have in my bronco by visually looking at the housing/cover etc....? thanks

D30's have smaller, oblong-looking chunks, and doesn't have ball joints, but king pins. If that doesn't help, see if there's a tag on there, D30's had a slightly different ratio than D44's (most all D44's were 3.54 or 4.09) If that doesn't help, shoot one of us a pic & we'll tell 'ya.

I guess the 44 has a castle nut on the top of the king pin, whereas the 30 has a plate with 4 bolts. By king pin i mean the vertical shaft that you wheel rorates left and right on. Hmm, sec lemme look for link. Here ya go.
