In general you have to drain the rear end, remove the cover, remove the carrier pin, remove the axles, then remove the carrier from the main shaft and replace the bearings.
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.
Hello lemofla: My name is Roger and I will help with your question. It is not necessary to remove the rear axle from the differential in order to replace the wheel bearing. This operation does require some special tools and alignment of the car to complete the job. You will need to remove the nut on the axle stub at the rear wheel hub. The rear brakes and spindle unit must be removed. The splash shieldrivets must be drilled out so the shield is not damaged. You will need a press and snap ring pliers in order to remove the bearing hub from the old bearing. Once the hub is removed you will need to press the bearing out of the spindle.When all is reassembled the dust shield should be reattached with new aluminum rivets. Reinstall the spindle and brakes. Torque the axle nut to 221 (ft.lb.). It may also be necessary to push the axle shaft stub out of the hub with a puller as the axle can be stuck. As you can tell this is not a quick fix and does take special equipment. So if you do this yourself PLEASE be careful and pay close attention to the way things came apart and be sure to have the car realigned. Should you not realign the car it will not drive right and you will prematurelydestroy the tire on the side worked on. Should you need further help please just ask. Please rate the answer. Thank You for using Fix Ya. Roger
Remove the brake drum, remove the plate that holds the axle to the brake backing plate. The nuts are under the hub flange (where the wheel studs are), there is a hole in this flange to insert a socket on an extension. (you will need to rotate the hub flange to reach all four nuts.) After you get these nuts off, attach an axle puller (slide hammer) to the hub and pop the axle half-shaft out. Take this to a machine shop and have them press the old bearing off and press the new bearing on. Slide the half-shaft back in, and reinstall the nuts.
Might as well replace both bearings (left and right sides) while you are at it. Mark which side the axles come out of, often they are not interchangeable.
Sometimes you can rent or borrow the axle puller from a major chain auto store such as Checker or Auto Zone. They should be able to recommend a machine shop also, if they don't have the correct press.
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.
The rear axle bearing? I'm going to presume that's the bearing you're talking about and not the rear main bearing, so please take that into consideration if you would
You're going to have to jack up the rear of the van, remove the tire and drum. Then you have to place a drain pan under the rear differential and remove the cover. After the cover is removed spin the rear axle (the one with the tire off) to locate the pin in the very center of the differential. On the right side you will see an 8mm (5/16) bolt head.
When you remove the locking bolt (the 8mm) and slide the pin out DO NOT SPIN THE AXLE WITHOUT THE CENTER PIN IN PLACE. Push in on the axle with the bearing to be replaced and a "C" clip will fall out of the differential. SLIDE THE CENTER PIN BACK IN and screw in the locking bolt a few turns. Once the "C" clip slips out, you can pull the axle out. If you don't have a bearing puller, it's best to rent one. Insert the bearing puller and pop the bearing out.
you must remove brakes, then remove axle nut, then remove upper control arm and finally tie rod stabilizer, remove axle from car then bearing can be accessed. this is a difficult job that requires special tools so be careful
Jack up vehicle and support with jack stands Take off wheel remove brake caliper remove caliper bracket remove rotor remove axle retaining nut cotter pin remove axle retaining nut remove axle from output flange pull axle out of vehicle hub and bearing assembly held in by 4 bolts
installation is reverse of removal. You will need to find out the torque specs for the axle retaining nut.
