Ford used Dana 70B and rear axles in 1977.5-1979 era 1 ton F350 trucks and most heavy-duty van/motor home chassis models. Dana 70HD axles were introduces for the D50 ambulance chassis in 1978 and E350 van chassis models in 1979. The difference is the size of the differential bearings. Standard Dana 70B axles have 3-13/16" diameter diff bearing cups. Dana 70HD axles have 4-1/8" diameter diff bearing cups. Over the years, Dana has primarily used Timken bearings when building their axles. For long life and dimensional consistency, Timken bearings are unmatched by any other brand of bearing I have used rebuilding axles over the past 30+ years in the business. When you are a shade tree mechanic dealing with a diff and pinion rebearing job without all the fancy gauging tools we have, you always want your new bearings to be the same overall thickness as the original bearings were when the axle was built so your pinion depth, pinion preload and backlash are within the tolerance limits when you are done with the job. Timken bearings will almost always deliver that type of accuracy, plus the steel quality and surface finish is the world's best.
