Agree with everyone and add :
The old 3/4 ton Suburbans (GMT400) had the same AAM axle assembly as the 1 ton dually of the same year. Only difference is in the leaf spring pack/hangers/brackets and the brake cyclinder/MC
Why parts counter will ask how wide your GMT400 3/4 ton Suburban has....there two and the difference is in the width of the shoes and drum. The wider shoe/drum also is a full floater rear end.
As for ball bearings vs rollers vs tapered rollers is that the balls have a smaller contact point with the race. Therefore lower rolling resistance
Rollers have a larger contact point and has a higher load rating vs a ball, but in regards to dia, the roller is rated to carry more
Tapered rollers has a much higher axial thrust load rating. Straight rollers almost none and balls has some.
Been advocating tossing the marketing nomenclature (1/2-3/4-1 ton, 150/250/350, 1500/2500/3500, etc) for years and just go with their GVWR. If they toss the 3/4 a step in the right direction, IMHO
