whatever dude.. i do gears everyday i know what bearings go into them and they are not the same. whoever told you them that they are the same axle is ignorant and has no idea what they are talking about. my boss tore down a 10bolt and a 44 and took a micromiter to every part of the axle and the only part that is smaller and weaker tha a 44 is the sidegears in the carrier. EVERYTHING else is bigger. the stubs are the same size but they are shorter.
