The axle housing assembly consists of a cast-aluminum center section, a removable cast-aluminum axle housing tube (3B210), and a differential housing cover (3N136). Both the axle housing tube and the differential housing cover use silicone sealant as a gasket. The hypoid-design gearset consists of an 8.8-inch ring gear (3A397) and a pinion gear (3N175). Two opposed tapered roller bearings support the drive pinion in the axle housing. A drive pinion collapsible spacer (4662), located on the pinion shaft, maintains pinion bearing preload. The pinion nut adjusts the preload. Differential bearing shims (4A451), located between the differential bearing cups (4221) and the axle housing, adjust the differential bearing preload and the ring gear backlash. The differential case (4205) 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 ) support the differential case in the axle housing. Removable differential bearing caps (4224) retain the differential assembly in the axle 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 left axle shaft (3A381) and the axle cluster gear shaft (7L253) are splined. The differential pinion shaft bolt retains the differential pinion shaft in the differential case. An embossed metal tag, bolted to the rear face of the RH axle tube, contains front axle identification information. CAUTION: Actuate the front drive axle with the wheels in a straight ahead position, and at light throttle only. A front axle actuator motor assembly (7G360), controlled by an instrument panel-mounted switch, actuates the front drive axle.

Introduction Some 2010 Prius vehicles may experience rear brake squeak when backing up or moving forward during the ?rst few brake applications when the brakes are cold. An updated rear brake shim kit is available to reduce the likelihood of this condition occurring. Repair Procedure 1. Test drive the vehicle to con?rm the squeak is coming from the rear brakes. The condition occurs more frequently when backing up during light brake pedal application after cold soak. 2. Remove rear brake shims. Refer to the Technical Information System (TIS) 2010 Prius Repair Manual: Brake – Brake (Rear) Brake: Rear Brake: Removal 3. Clean the rear brake pad backing plates with a clean shop towel and apply a small amount of black disc brake grease to the backing plate of each rear brake pad. NOTE Make sure disc brake grease is not applied to the lining of the rear brake pads. 4. Install the No. 1 Anti-squeal shims. Install the No. 2 Anti-squeal shims. Figure 3. 5. Using the Variable Pin Wrench (SST 09960-10010), slowly rotate the caliper piston until the piston groove is positioned as shown in the illustration below. 6. Install new rear brake anti-squeal shims with brake pads into the rear caliper assemblies brackets. Refer to (TIS), 2010 Prius Repair Manual: Brake – Brake (Rear) Brake: Rear Brake: Installation NOTE • When installing the rear disc brake caliper assembly on the rear disc brake caliper mounting bracket, ensure the protrusion on the brake pad is centered in the caliper piston groove. • It is important to ensure the protrusion is not contacting the outer edges of the caliper piston groove. (both sides) 7. Road test the vehicle to con?rm the condition has been reduced.
