International Front Axles Explained: I-Beam, Torsion Bar IFS, and Dana 27/30/44/70 Differences

Dan from Binder Boneyard discusses common misinformation about International truck, Travelall, and Scout front axles, outlining major designs and year ranges. He covers two-wheel-drive setups including I-beam axles used through 1973 (with 1974 switching to independent), the 1010 torsion-bar independent front end with obsolete steering/suspension parts and hard-to-source Lockheed brake components, and rare Scout 80/800 and Scout II 2WD tube axles. He then traces four-wheel-drive development from early heavy-duty 1953 trucks and 1956 S-120 closed-knuckle Dana 44-based axles, through Scout Dana 27 and Dana 30 closed-knuckle designs, to open-knuckle Dana 30/44 changes in the early 1970s and the move to disc brakes (especially Scout II). He highlights weight-rating variations, Dana 70 one-ton fronts, parts availability issues, and urges verifying what axle is actually installed before ordering parts.
