d44 axle

In 1987 was there any difference between the front Dana 44 axle in the J10 and J20 other than one having six wheel studs and the other eight? Thanks

Nope. At least from the time of the open knuckle(post 74?)....i have put j20 hubs, mid 70s chevy 10 bolt hubs, on to several late 70's and early 80s j10 44s. Now some will tell you the j20 axle has thicker axle tubes. Not sure about that.
J20

Yep. It's rated for higher GVWR. Supposedly it has a designation as a Dana 44HD.

The J20 Rotor/caliper bracket are 1" larger OD however it all will swap between the two.

The tube wall thickness issue is somewhat obscure. I have a few dozen FSJ axles here at the yard. I noticed that all early 1974, 75, and possibly 76 FSJ axles have thick wall tubes when compared to later axles. I suspect that some time in the mid 1970’s. there was a cost/weight reduction for the front Dana 44 and thinner tubes were used for the lighter GVW FSJ’s. The J20 axles all have thick wall tubes.

FWIW, the only time"back in the day". I had a wealthy customer who loved to chase coyotes and the he dud to front D44s was terrible, so when we talk about tough these days, i think mall krawler.
