Ford 7.5-Inch Ring Gear Rear Drive Axle/Differential

Rear Drive Axle and Differential

Rear Drive Axle And Differential:

^ The axle housing consists of a cast center section with 2 steel tube assemblies and a stamped differential housing cover. The differential housing cover uses silicone sealant as a gasket.
^ The hypoid-design gearset consists of 7.5-in ring gear and a drive pinion gear. Two opposed tapered roller bearings (drive pinion bearings) support the drive pinion in the axle housing.
^ A drive pinion collapsible spacer, located on the differential pinion shaft, maintains drive pinion bearing preload. The pinion nut adjusts the drive pinion bearing preload.
^ Differential bearing shims, located between the differential bearing cups and the axle housing, adjust the differential bearing preload and the differential ring gear backlash.
^ The differential case is a one-piece design with 2 openings to allow for assembly of the internal components and lubricant flow. Two opposed tapered roller bearings (differential bearings) support the differential assembly in the axle housing. Removable bearing caps retain the differential assembly in the axle housing.
^ Inside the differential assembly, the differential pinion shaft supports 2 differential pinion gears. The pinion gears engage the differential side gears, to which the axle shafts are splined. The differential pinion shaft lock bolt retains the differential pinion shaft in the differential case.
^ An embossed metal tag, bolted to the differential housing cover, contains the axle identification.
