Rear axle seal replace

Pull rear differential cover, remove small bolt/pin that holds pin in, remove pin, push axles in and remove both c clips, pull axles out and then remove seals....reverse procedure but ensure to fill diff with gear oil until it comes out the fill hole.

its not that big of a job block your front wheels raise the rear end and support with two jack stands remove your tires drain your rear differential and remove the differential cover remove the 10mm bolt that holds the stud in place when you remove the stud the side gears will fall out giving you room to push the axles forward so you can remove the retainers once the retainer is removed you can remove the axle just watch the spider gear doesn't fall out of the differential do the same for the other axle once the axles are removed use a seal puller to remove the old seals and a seal installer tool to press the new ones in place both tools are available at any local auto parts jobber. After installing the new seals put some white lithium grease in the seal and install the axles line the axle with your spider gear and push all the way forward then install your retainer and pull the axle back seating the retainer do the same with the other axle after that is done install one side gear push you stud in place and line it up with the other side gear be very careful if there are shims on any of the gears keep them with that gear and make sure they go back in the place they came from try to mark them with a paint marker before removing. After installing the stud with the gears install your bolt I would use lock tight blue on the bolt and clean the rear cover put your permatex blue on the cover, bolt it up and fill the rear differential with quality 85w90 gear oil make sure if your vehicle calls for a friction modifier add that to the mix if you don't you will get allot of chatter possibly damage to the clutch pack and don't believe lube adds when they say modifier not needed if you use there lube That is a Royal mistake I replaced all the fluids with the brand boasting that's all you need and in one weeks time my rear clutch pack was chattering like a kid out in the cold I then added the friction modifier and problem solved it went away, Your done good luck and God Bless

You will need to remove the rear diff cover. There is a small bolt that secures the pin that the spider gears ride on. remove this bolt, and then remove the pin(you might call it a shaft). Remove the caliper and rotor from the side you are replacing, and push the axle in. Inside the differential, you will see what we call a c-clip on the end of the axle shaft you just pushed in. Sometimes this clip if it is in the right position, will fall out on it's own. If not, slide it off, and go pull the axle out. Now you can pry out the seal and replace it. There will be a pipe plug with a square recess on the front side of the differential. You can put a 3/8 drive ratchet in the recess and unscrew it. This is the fill plug. You fill the rear end untill it runs back out of this hole. It will be located about half-way up from the bottom of the differential housing.

kiker graham, Yes there is a clip that holds the axle in the differential. First jack up the back of the vehicle and support with jack stands. Put the transmission in neutral. Remove the wheel and brake drum from the axle you want to remove. Place a catch basin under the differential and remove all the bolts on the rear cover of the differential. Remove the cover and let the gear oil drain out. You may have to move the break line to remove the cover. When the oil has drained out turn the drive shaft until you see a small bolt in a recess on the right side of the assembly on the opposite side on the main drive gear. This is an 8MM bolt that has to loosened very carefully. First, using a punch, place the punch on the head of the bolt and hit it a few times with a hammer to "loosen" it up. This is done to avoid breaking the bolt. If this bolt is broken then you are going nowhere with this job. BE VERY CAREFUL when removing this bolt. When the bolt is out you can move the pin that it is holding. You will notice that this pin is very close to the ends of the axles. Do not completely remove this pin as the side gears will fall out. Pull the pin out only as far as you need to, to push the axle in towards the center of the vehicle. There is a C clip that will fall out when you have done this. Sometimes you have to spin the C clip to get it to fall out. Pull the axle out only far enough to put the center pin back in place. After you do this push the center pin back in and put the small bolt back in to hold it in place. Remove the axle. If the axle is bent and you say it is then it would be a good idea to replace the axle seal at this time. You can use the axle itself to remove the seal. Use the groove where the C clip sits. Place on the inside of the seal. Using the axle as a pry bry, remove the seal. Replace the seal and put the new axle in. You will have to move the axle around a little to get it to engage the splines on the inside of the side gear. Once again pull the center pin out only far enough to push the axle all the way in. Place the C clip in the slot at the end of the axle and pull the axle out as far as you can. This wont be much. Push the center pin back in and replace the little lock bolt and tighten it up. Clean the cover and the back of the differential and use silicone to seal it. There is a fill hole on the front side of the differential. The plug for this hole will accommodate a three eigths ratchet. Fill the differential until the gear oil starts to spill out of the hole. Replace brake drum and wheel. Good luck with this.

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.

To change the rear seal, yo will need to raise and support the rear of the vehicle. Remove the wheels and drums or rotors (depending on drum or disc brakes.) Remove the rear differential cover bolts and the cover (have a drain pan under the differential) You will likely need to turn the driveshaft so the center pin bolt is acessible at the back or the differential. This is a 5/16" (or 8mm) bolt that is on the right (passenger) side of the differential carrier assembly. I recommend a new bolt be installed here on reassembly. Once the retaining bolt is out, slide the center pin out enough to allow the axle shafts to be pushed in toward the center of the diff. to remove the "C" clips that retain the axle shafts in the carrier assembly. Be careful if you happen to pull the center pin all the way out not to allow the carrier assembly (has the ring gear mounted on it) to turn, as this can rotate the spider gears out of alignment causing a headache on reassembly. With the "C" clip removed the axle shaft can be pulled out of the diff. Inspect the bearing area of the shaft for rust, pitting, or scoring. Remove the old seal and carefully install the new one. Reverse proceedures to install. Take care to note the "C" clips and center pin bolt are properly reinstalled. Fill with 2.5 to 3 quarts of rear axle grease for you vehicle.
good luck.

1. Install axle shafts as outlined.

Jack up vehicle and support on stands. Remove wheels. Remove differential cover . Locate and remove lock pin that holds cross shaft in. Slide cross shaft out. Push axle inward to release axle c clip. Remove axle and pry out old seal. Install new seal with proper tool.Add some lube to the seal lip to aid axle intallation. Revese removal procedure. This is for a "c" type axle.
Another type has 4 nuts attaching a retainer plate to the backing plate behind the axle flange. In this case the 4 nuts are removed and the axle will come out. This may require a little effort. I think that you have a "c" type axle in your vehicle. Hope this helps. Moe

Wheel, brakes etc that are in way of pulling axle out have to come off. Drain rear end fluid, remove rear housing cover, remove bolt that holds pin in differential, remove differential pin, push in slightly on axle to remove "U" clip that holds shaft in, then slide shaft out. replace seal. Reverse procedure for re-install & fill with gear lube. If any questions, get back to us.

if you need to change the axle seals here is the process. You need to remove the rear wheels. Remove the brake drums if so equipped. Remove the rear cover on the differential. Turn the differential until you find the bolt that holds the cross shaft in place. Remove the bolt and pull the cross shaft out. Then you will see the axle ends. Push the axle in towards the center of the axle. You will need to remove a C clip retainer from the axle end. You can then remove the axle and gain access to the seal. Repeat the process on the opposite side. Then reverse the disassembly process. Place the cover back onto the differential housing and refill the differential. Good luck.
