Without Traction-Lok

DESCRIPTION
The rear axle assembly contains the following features:
- An integral-type housing, hypoid gear design. (The centerline of pinion set is below centerline of ring gear.)
- The hypoid differential ring gear and pinion consists of a 224 mm (8.8-inch) diameter ring gear and an overhung drive pinion which is supported by two opposed tapered roller bearings.
- Differential pinion bearing preload is maintained by a differential drive pinion collapsible spacer on pinion shaft and adjusted by pinion nut.
- The rear axle housing assembly consists of a nodular iron center section and a cast-aluminum axle housing cover.
- The axle housing cover uses silicone sealant rather than a gasket.
- The differential case is a one-piece design with two openings to allow for assembly of internal components and lubricant flow.
- The differential pinion shaft is retained by a threaded differential pinion shaft lock pin assembled to differential case.
- The differential case is mounted in rear axle housing between two opposed differential bearings.
- The differential bearings are retained in rear axle housing by removable bearing caps.
- Differential pinion bearing preload and ring gear backlash are adjusted by differential bearing shims located between the differential bearing cup and the rear axle housing.
- The halfshafts are held in differential case by a driveshaft bearing retainer circlip located on inboard CV joint stub shaft pilot bearing housing.
- When each halfshaft is installed, driveshaft bearing retainer circlip engages a step in differential side gear.

BRAKE SYSTEM, ANTI-LOCK-REAR
- Rear anti-lock brake system (ABS) components consist of rear brake anti-lock sensor and rear brake anti-lock sensor indicator.
- Rear brake anti-lock sensor is attached to rear axle housing and is not adjustable.
- Rear brake anti-lock sensor indicator is attached to inboard CV joint outer race.

OPERATION
Rear drive axle operates as follows:
- Rear axle drive pinion receives its power from the engine through transmission and driveshaft.
- Pinion gear rotates differential case by engaging with ring gear, which is bolted to differential case outer flange.
- Inside differential case, two differential pinion gears are mounted on differential pinion shaft which is pinned to differential case.
- These differential pinion shafts are engaged with differential side gears, to which halfshafts are splined.
- As differential side gear rotates, it rotates halfshafts and rear wheels.
- When it is necessary for one wheel and halfshaft to rotate faster than the other, the faster turning differential side gear causes differential pinion gears to roll on the slower turning differential side gear to allow differential action between the two halfshafts.
