Toyota 90311-62001 Seal, Oil

To remove the freewheel hub, start by taking off the front wheel bearing assembly. Next, detach the bolts that secure the brake backing plate and spindle to the steering knuckle, then remove the backing plate, including the eight spindle mounting bolts, dust seal, and cover. If the vehicle has front drum brakes, remove the complete brake assembly and secure it aside without disconnecting the hydraulic line. Tap the spindle with a soft-faced hammer to separate it from the steering knuckle, and inspect the spindle bushing for wear, replacing it if necessary. If equipped with anti-lock brakes, disconnect the electrical connector and remove the speed sensor. Turn the axleshaft until the flat spot on the CV housing aligns with the top of the steering knuckle, then pull it straight out of the axle housing, being careful not to damage the axleshaft seal. If replacing the axleshaft oil seal, use a suitable puller to remove it from the housing. For overhaul, secure the inner axleshaft in a vise with soft jaws or wood, then use a brass drift and hammer to drive off the joint and outer shaft. Remove the ball bearings from the inner race and cage one at a time, then tilt the cage and inner race to pull them out. Remove the inner race from the cage by aligning its lands with the cage openings, turning it 90 degrees, and pulling it out. Clean and inspect the inner parts of the joint for wear or damage, replacing any necessary components. To reassemble, coat the inner parts and the inside of the outer shaft with molybdenum disulfide grease, insert the inner race into the cage, and ensure the protruding end of the inner race aligns with the wide side of the cage. Assemble the cage and inner race to the outer shaft, ensuring proper orientation, and install new snap-rings on the inner axleshaft. Place the CV joint in the vise and install the axleshaft while compressing the inner snap-ring with a screwdriver, ensuring the axleshaft cannot be pulled out of the joint. If necessary, install a new oil seal and lubricate the splines on the inner end of the axleshaft with grease, keeping it straight as you insert it through the steering knuckle and into the axle tube, ensuring proper engagement with the differential. The remainder of the installation follows the reverse order of removal.

The axleshafts can be withdrawn from the housing with the differential retained in the housing this is necessary when changing the bearings and oil seals or when pulling off the differential carrier from the rear axle housing. First, use a hydraulic jack to lifted the back of the car off the ground and supporting it with jackstands while chocking the tires of the front section of the vehicle. Then, you should withdraw the rear wheels, unlock the parking brake, and then detach the brake drums. Pump out the differential oil using an oil drain pan and after pumping the oil to the required amount, screw the drain plug back into place. Remove the rear differential cover; next, take out the pinion shaft pin, pinion shaft, and the pinion shaft spacer spinning the differential to have better access. Found that if an assistant applies inward pressure on the outer flanged end of the axleshaft, while the other rotates the vehicle to align the groove, you pull out on the axleshaft lock clip, and pull the axleshaft straight out. Check the condition of axleshaft bearing and seal, if the bearing is to be replaced, use slide hammer with internal puller jaw to extract it. New oil seal should always be lubricated with multi purpose grease on the inner lip before refitting of the axleshaft. Last but not the least, verify the torques and replace all the components in the reverse order, replace the differential cover now fill the rear axle.
