The present disclosure relates to a gearing arrangement for a tandem axle assembly for a vehicle that reduces parasitic losses associated with the bearings of a drive pinion. The gearing arrangement includes a first helical gear in driving engagement with an input shaft and a portion of an interaxle differential; a second helical gear coupled to a pinion shaft with at least two bearings mounted on either side of the second helical gear on the pinion shaft; and a drive pinion coupled to the pinion shaft and meshingly engaged with a ring gear. The ring gear is in driving engagement with a forward differential assembly. The first helical gear and second helical gear are meshingly engaged and have a predetermined gear ratio.
