SOURCE: Rear Axle Leak

It might be the bearings that failed and letting the axle rest on the seal. Its a common problem for these cars. I've replaced mine and it did it again so now im replacing the rear end.

SOURCE: Left rear axle seal is leaking differental oil.

ok then here is the procedure  1 take off the axle nut
2 on the lower control arm you will find a large nut and bolt i belive the nut is a 21mm and the bolt side is an 18mm. this bolt is the one at the knuckle near the brakes. remove it
3 you will need to pull the knuckle out of the way or a helper to pull the knuckle out of the way so you can slip the axle out of the knuckle.( its a tight fit but there is room to slip it out.)
4 use a pry bar to pop the axle free of the diff. hosing its held in by a spring clip make sure the clip comes out with the axle if it gets stuck inside you will have to fish it out.
5 use a pry bar or screwdriver to pry seal out of housing then use a flat object that contacts the entire rim of the new seal so it can evenly be installed with out getting smashed and tap it in with a hammer. ( a good trick here is to use some grease and pack it into the new seal where the spring is this will prevent the spring from being shocked out of the seal during instalation . the spring keeps tension on the rubber in the seal so it stays tight to the shaft it is sealing.)
6 then revers the above steps. also make sure you are using the right gear lube it will most likely be 75w-140 but make sure you check your owners manual will tell you if it doesnt say on the diff cover. you can cause a lot of damage if you put in the wrong thing. and make sure  you feel the axle spring clip snap into place.
as a note there are two types of axle seals that are used on these so if the new seal looks different than the old seal then the folliowing will be important to you.the seals on these have been redesigned so if you axle has what looks like a cup or dust cover pressed onto the shaft where it goes into the diff the new style does not use this and it will prevent the axle form going in all the way so the spring clip will not lock in and you will have a leak. so you will have to remove it and install the axle without it.

Hello, it's not "easy" but, it's doable.
You'll need to follow the instructions and don't take shortcuts. ask for help if you need it.
Use this link to get an idea of what is involved. Ignore the "remove transmission" part. It can be done without removing the tranny. If you decide to do this buy a service manual to help you. If you have any questions feel free to ask.

SOURCE: REAR AXLE SEAL LEAKING ONTO BRAKE SHOES NEED INSTRUCTIONS ON HOW TO FIX

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

SOURCE: leaking rear axle seal

Because this would be so hard to describe, your best solution would be to go to a store like autozone, or kragen, and get a haynes manual for your truck. You will be very glad you did. It will be the best thing you can get for yourself. And that book will tell you exactly how to replace EVERYTHING in your truck.

Good luck.

I have grease coming out of my rear wheel housing what could be the problem. 2007 chevy silverado 2500


It shouldn't have grease are you sure it's not gear oil? And if it is leaking gear oil that means the seal at the axle hub is bad and needs to be replaced. Sounds bad but not to hard to replace, The seal is only a couple of dollars if you do it yourself! Make sure that it is not your brake caliper or wheel cylinder leaking.

I was told today that the front and rear differential seals, as well as a transfer case output seal were leaking on my 2006 Chevrolet Silverado 2500 HD Diesel. This truch has about 70,000 miles on it, but...


These are such easy seals to do, why bother trying to save a few bucks?
But seals also are suppose to leak, so that they are self lubricating. As long as you don't have a problem keeping the differetials fulled, don't worry about it.
Each seal is less then $75. But you can do yourself in less then an hour apiece, for $5.
