The differential housing (4010) consists of a cast aluminum housing and a cast aluminum
differential housing cover (4033). The differential housing cover uses silicone sealant as a
gasket.
The hypoid-design gearset consists of a 8.8-inch differential ring gear and a drive pinion gear.
Two opposed pinion bearings (4621) (4630) support the drive pinion gear in the differential
housing.
A differential drive pinion collapsible spacer (4662), located on the drive pinion gear shaft,
maintains pinion bearing preload. The pinion nut adjusts the preload.
Differential bearing shims (4067), located between the differential bearing cups (4222) and the
differential housing, adjust the differential ring gear backlash and the differential bearing
preload.
The differential case (4204) is a one-piece design with two openings to allow for assembly of
the internal components and lubricant flow. Two opposed differential bearings (4221) support
the differential case in the differential housing. Removable differential bearing caps retain the
differential assembly in the differential housing.
Inside the differential case, the differential pinion shaft (4211) supports two differential pinion
gears (4215). The pinion gears engage the differential side gears (4236), to which the halfshafts
