The axleshaft for a 20 (bottom) has a visibly smaller diameter than the shaft for a 44 (top)-another reason the Model 20 is inferior in stock trim. The bearing assemblies are weaker because they're smaller in diameter and width than the bearings in a 44, which means there's less bearing surface and, therefore, more friction and heat.
