71 K10 6 Lug Hub Spec Question
Based on what I've been able to learn the front axle on my 71 K10 is a dana 44 (casting # C-31256), 6 lug, small bearing hub. The inner diameter of the inner bearing is 3 1/4" inside lip to inside lip. The local junkyard has a 6 lug hub from a 75 they say has an inner bearing diameter of 3 1/4" inside lip to inside lip that will fit. Since the inner bearings determine if it's small/big bearing and the replacements have the same diameter, shouldn't they be a direct fit replacement? Does anyone know if the 75 replacement hubs will work?
