I bought a 3/4 ton rear axle Saturday, 14 ff... The guy was tryin to sell me the matching front... he says its a 44 but the hubs are WAY bigger than anyy 44. At the end of the axle tube it bells out. It doesn't just but up to the ball joint purches like my 44. He said something about there being 2 44's??? One housing fits a set of gear ratios and one fits another set... Any ideas???
