How do I replace the rear axle seal on my 95 roadmaster?
I heard metal on metal and found gear lube on my Left rear wheel. I checked the differential and couldn't feel any gear lube. I have added almost two bottles, the nosie went away, but the gear lube is leaking out, what will I need to correct this, how long should I plan to spend doing it? Thanks for your help

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
Raise the vehicle and properly support it. Remove the wheel and drum. Remove the rear diff cover, have a drain pan underneath to catch the gear oil. Place the trans in nuetral, chalk the front wheels to keep vehicle from moving if you forget to put it back into park befor you lower the vehicle. Rotat the differential until you see the bolt that holds the diff pin in place. Remove the bolt, 5/16 or 8 mm I believe. You can then remove the diff pin, do not rotate the diff with the diff pin removed! Push the axle in, you can then remove the C-clip that holds the axle to the side gear, it will usuall drop or just fall out. Pull the axle out of the rear diff and replace the seal.
Put everything back together. Use black or grey RTV to reseal the diff cover making sure o clean up both surfaces as best you can. Put trans in park. Lower the vehicle. Remove the fill plug from the side of the differential and fill with gear lube until lube comes out the hole. Reinstall the plug and your good to go.
Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Remove rear brake anti-lock sensor . Push axle shaft inward until u-washers at button end of the axle shaft are clear of side gear recess.
CAUTION: Do not damage inner wheel bearing oil seals when removing axle shafts from rear axle housing. In addition, axle shafts should be completely removed from rear axle housing.
Remove u-washers and pull axle shafts out of the rear axle housing.
If what you see leaking is very oily and does not evaporate, likely it is an axle seal. If there are no leaks in the brake system, that's the only thing back there that can leak. If the axle bearing is going away, it can damage the seal so make sure you look for small shiny metal flakes behind the seal when you replace it or you will be doing the job again very soon. Can't remember...that IS rear wheel drive right?
Not that difficult, raiseand support the rear of the truck and remove the wheels. Might as well replace both sides so you know you have new seals, remove the differential cover and drain the fluid. Once differential is opened and cleaned , remove the axle "C" clip that hold the axle in place and slide the axle out. Once the axle is out remove the wheel seal and clean around the area. This would be a good time to replace the wheel bearing too since you have access to them and there not that expensive. Install the new bearing and seal, note make sure you oiled the bearing and seal before installing it back and take care when installing the axle back in and "C: clip. Use RTV silicon gasket maker to seal the differential cover and wheels back on and lower. If your lazy like i am, you can drain the differential fluid and replace it with a 50/50 mix with gear oil and Lucas engine oil additives. That may stop the leak and get you a few more miles. You gear oil is (ford 75W-140) (Dana 80W-90)and the capacity is 2.6 liters and 3.5 liters if you have the 10.25 Ring gear. Good luck and hope this helps.
