I work as a mechanic and I have been doing lots of work on a 69 GMC half ton 4x4. I have run in to a problem with the front axle. It has what appears to be a D44, but it is closed knuckle (you have to remove a pipe plug to see the u joint). I don't recall these rigs coming like that. Is it a Jeep part (Gladiator or?) or a Chevy part that I don't know about?

early chevy's used closed knuckle 44's so it is a factory part but I have never worked on one so that is all the help I can give you.

Yup, all the older (pre '72 or so) Chevy's had closed Knuckle Dana 44 fronts, weak. Good new is a later open knuckle 44 will bolt right in, well, mostly.

Thanks, now that I think about it, all of the ones I recall seeing have had axle swaps done. It must be 69 and earlier that has them (4 wheel drum).

yup

My 68 IH pickup has a closed knuckle 44 up front to.

there are 2 typs

the 1/2 ron which is a small ball type (the ball is a bit bigger then a soft ball)

then the 3/4 tone which is a big ball about the size of a volly ball. and has a grate lod capasaty (higher then the open knuckle) and uses the same U joint as the closed knuckle 60 and I hear that U joint is bigger then todyas open knucke

so the 3/4 version is a prety stout axel, turning radus sucks but beefy

My 1960 k20 had a closed knuckle dana 44 front. I ran it till it fell apart. It is well worth it and easy to swap. I thru a 76 3/4 ton 44 under it the only difference was the tie-rod on the drag link and the brake lines.
