Does anyone know the difference in the two front and rear differential assemblies listed in ORD 9SNL G740?

Are you asking about the difference between the front axle differential assy PN7348603 and the rear differential assy PN7372679? The front axle is a Dana model 25and uses a 7.75" ring gear and the rear axle is a Dana model 44 and uses a 8.5" ring gear so the assemblies are physically different in size to accommodate the different size ring gears, otherwise very similar in construction.
