Diff & Pinion Bearings 72-84 Dana 70HD Rear Axle

Shop Now for Differential Bearings and Pinion Bearings for 1972-1984.5 Dana 70HD Series Rear Axles in Dodge D300, W300, D350, and W350 trucks.

1972-1984 vintage Dodge Dana 70 and Dana 70HD rear axles share many of the same parts, but they use different differential bearings and bearing cups. The standard Dana 70 rear axle used in 1972-1984.5 1 ton trucks and motorhome chassis plus some 400 series 1-1/4 ton motorhomes have differential side bearing cups that have an outside diameter of 3-13/16".  The Dana 70HD Heavy-Duty rear axles found in most 400 series and 500 series Dodge motorhomes feature 4-1/8" diameter differential side bearing cups. Also, Dana 70HD axles use a combination of outside bearing cup spacers and shims between the differential and differential bearings to set gear backlash and differential bearing preload. Standard Dana 70 axles just use shims between the bearing and differential case.
