Put the rear up on jack stands and remove the wheels and brake drums. Then unbolt the rear differential cover and drain the gear oil. Then, you remove the pinion securing bolt. DO NOT ROTATE THE WHEELS AS THIS CAN CAUSE THE PINION GEARS TO FALL OUT. Push the rear axle shaft inward toward the vehicle and remove the "C" clip that secures the axle to the pinion gears. Then pull the axle shaft outward and out of the axle housing. Inspect the axle shaft for scuffing and excessive wear on the place where the wheel bearings rest. If there is excessive wear, you can use a "repair bearing", which is modified to install so it runs on an unworn part of the axle shaft. Otherwise a regular replacement bearing is fine. You need a slide hammer removal tool to extract the old bearing from the axle housing, and a bearing install tool to insert the new one without damage. Once the new bearing is in, reinsert the axle shaft, secure with the "C" clip, and pull outward to latch the "C" clip into its recess. Install the pinion bolt. Reinstall the differential cover with appropriate gasket or sealer. Fill differential with approved gear oil in the recommended amount. Ensure that if the rear is a positraction rear end there may be an additive required to the gear oil for proper operation.
not very much info. 1/2 ton? 2wd? If it is a standard pickup there are "C" clips that hold the axles in. You will have to remove the 3rd member cover and remove the clip. This is after you have removed the wheel and brake drum. The axle will slide out and the bearing will remain in the axle housing.Messy job. Take it to your mechanic.
To remove the rear axle to replace a bearing you have to remove the rear differential cover and remove the small retaining bolt holds the spider gear shaft in place and then slide this shaft out far enough to remove the "C" shaped axle shaft retaining clip. Once this clip is off then the axle can be slid out and the bearing & seal replaced. Make sure that none of the spider gears or thrust washers behind them get out of place and you should use a new retaining bolt when reassembling the differential components as they come [or should come this way] with thread locker to prevent them from coming loose.
Yes you do have to pull the axle and make sure you put everything back in the same place you removed it from. The ring and pinion shouldn't have to be bothered. You will have to remove the rear end cover to remove the axle. Its very easy to do. There is a pin inside the rear end that has to be removed to pull the axle. Pay attention to how you take it out and put it back the same way. It sounds as if you can do this with no problem.
Dear Jimmy, This repair is an intrusive repair if you have never done it.A chilton's manual can be purchased at your local auto parts store for $20 for your vehicle. Jack up the rear of vehicle and support it.Remove the rear tires.If the vehicle came with disc brakes remove the caliper and bridge, if not then remove the brake drum.Remove the rear diff cover, with a drain pan to catch the fluid.Remove your rear pinch thru bolt, your pin will then slide thru.Push both axles in to release and remove the u clips on the inside of the carrier assy, then pull both axles out.Remove the outer axle seal, throw away, ten using a bearing puller tool remove the bearing from the axle tube, install new bearing ad seal with drivers and reinstall axles.any other questions get back to me...I'm here to help!!!
This is a rear wheel drive vehicle? Are you sure it's not a brake squeal?
The bearing sits in the end of the axle tube and is lubed with the differential fluid. You need to dissasemble the differential to remove the axle, to remove the bearing. You need a puller for that type of bearing.
you must remove the cover on the rear end, remove the 5/16" bolt on center carrier, push the pin that the bolt whent through out, thenp push the axle in, a c clip will fall out of the carrier then axle may be removed,

REMOVAL AND INSTALLATION
NOTE: Whenever replacing the rear axle lubricant, use Rear Axle Lubricant XY-90-QL (ESP-M2C154-A) or equivalent. Removal CAUTION: The rear brake anti-lock sensor must be removed before the axle shafts are removed. The rear brake anti-lock sensor is bolted on the rear disc brake caliper anchor plate.
Raise vehicle to desired working height. Refer to Section 00-02 . Remove rear wheel (1007) and tire assembly. Remove rear disc brake calipers (2552) and rear disc brake rotors (2C026) .
Clean all dirt from area of axle housing cover with a wire brush and/or cloth.
Drain rear axle lubricant by removing the axle housing cover .
Push flanged end of the axle shafts toward the center of the vehicle and remove the rear axle shaft retaining u-washer from the button end of the axle shaft .
Remove axle shaft from the rear axle housing , being careful not to damage the inner wheel bearing oil seal (1177) and rear brake anti-lock sensor ring.
Installation NOTE: Check for presence of rear axle shaft o-ring (4A332) on the spline end of the shaft and install if not present. CAUTION: Care must be taken not to let axle shaft splines damage oil seal or bearing assembly.
Carefully slide axle shaft into rear axle housing without damaging rear wheel bearing (1225) or rear brake anti-lock sensor indicator (2C189) . Start splines into side gear and push firmly until the button end of axle shaft can be seen in the differential case .
Install the rear axle shaft retaining u-washer on the button end of the axle shaft splines, then pull the shaft outboard until the shaft splines engage and the rear axle shaft retaining u-washer seats in the counterbore of the differential side gear .
Position the differential pinion shaft through the differential case and differential pinion gears , aligning the hole in the differential pinion shaft with the lock bolt hole. Apply Rear Axle Lubricant to differential pinion shaft lock pin . Install differential pinion shaft lock pin and tighten to 20-41 Nm (15-30 lb-ft).
CAUTION: Differential pinion shaft lock pin must be tightened to specification using Stud and Bearing Mount E0AZ-19554-BA (WSK-M2G349-A1) or equivalent.
NOTE: Axle housing cover must be installed within 15 minutes of application of the silicone rubber or new silicone rubber must be applied. CAUTION: Make sure machined surfaces on both axle housing cover and rear axle housing are clean before installing the new silicone sealant. Inside of axle must be covered when cleaning the machined surface to prevent axle contamination. Tighten the cover bolts in a crosswise pattern to ensure uniform draw on axle housing cover .
Apply Silicone Rubber D6AZ-19562-AA or BA (ESB-M4G92-A or ESE-M4G195-A) or equivalent. Install axle housing cover and tighten retaining bolts to 28-38 Nm (38-52 lb-ft).
