DISASSEMBLY AND ASSEMBLY
Universal Joint —
Single Cardan, Flange Yoke
Disassembly 1. Remove the driveshaft (4602). For additional information, refer to Driveshaft in this section.
2. CAUTION: Under no circumstances is the driveshaft assembly to be clamped in the
jaws of a vise or similar holding fixture. Denting or localizing fracture can result, causing
driveshaft failure during vehicle operation.
Place the driveshaft on a suitable workbench, being careful not to damage the tube.
3. NOTE: If components are not marked and installed correctly, driveline imbalance can occur.
Index- mark the positions of the driveshaft components.
4. Clamp the U- joint tool in a vise.
5. Remove all four of the snap rings.

z
The axle housing assembly consists of a cast center section with two steel tube assemblies and
a stamped differential housing cover (4033). The differential housing cover uses silicone sealant
as a gasket.
z The hypoid- design gearset consists of 7.5- inch ring gear (4209) and a drive pinion gear (4209).
Two opposed tapered roller bearings support the drive pinion in the axle housing (4010).
z A collapsible spacer (4662), located on the differential pinion shaft, maintains pinion bearing
preload. The pinion nut adjusts the preload.
z Differential bearing shims (4067), located between the differential bearing cups (4222) and the
rear axle housing, adjust the differential bearing preload and the ring gear backlash.
z 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 tapered roller bearings (differential
bearings) (4221) support the differential case in the axle housing. Removable bearing caps
(4010) retain the differential assembly in the axle housing.
z 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 axle
shafts (4234) are splined. The differential pinion shaft lock bolt (4241) retains the differential
pinion shaft in the differential case.
z An embossed metal tag, bolted to the differential housing cover, contains rear axle
identification. Klj . 3 ba
