Rear Axle Seal Leaks?????

Hey folks,

Changed out the pads and rotors on my truck this weekend....... When I took off my rear rotors(disc all the way around) I discovered that my e-brake shoes on both left and right wheels were covered in oil.
Guessing that the axle seals are bad and that it probably isn't the best thing to find....???
Who has run into this issue and what does it take/cost to fix? How long do I have till something worse happens???

Pretty well sucks!

Thanks,

Joe H.

It is a real easy job. I picked up the stock spindle nut kit QK4008C and axle seals from quad4x4.com. Mine is a 3500 so the discs are attached to the hubs. Everything had to come off in order to replace the e-brake shoes. I got the new shoes from Rockauto.com. Just be careful that the seals are installed correctly in the hub.

It's easy. The seal is cheap and since you're already doing the brakes you have most of it apart anyway. The only specialty part really is the socket to take the axle nut off.


FYI the cover to a cutting torch tank works great to pound the seal back on.

You can buy the axle nut socket I think it was a rounded 2 1/4 in. and the axle seals (get heavy duty double lipped) were about 11.00 and put a light coat of silicone around the outer edge before you put them in,the axle nut torque I think 125 ft. lbs and back off a 1/4 turn.

its not that easy folks...everything has to come off, its not that hard but its just a PITA ...time consuming. the seal is like 30 bucks from the stealership and just make sure you put everything back together ok...i might have to do another one soon. damn dodge. the socket is like a 2 and 7/32 i think. i bought the "axle nut socket" from autozone and had to beat the HELL out of it to get it on the nut...obviously it wasnt the right size..

It is that easy I have done them numerous times,I can replace the seal in about 15 min.
What do you mean by everything has to come off?

Take the tire off,take axle nut off,pull of hub assembly,install new seal.
You do not have to remove brakes shoes unless there covered in gear oil
also after you put it all back together you should tip the axle side to side to allow gear oil to refill the hub,and I use medium (blue) loctite on the axle bolts and torque to 75ft.lbs

I'm replacing the rear passenger oil seal on my 2009 2500. It leaks so bad that it was throwing gear oil in the wheel well. All fasteners are removed however the hub assy. will not come off. Thought I would ask for ideas before using a BFH or slide hammer.

No pics but you remove the wheel.
Take,off the 10 bolts (9/16") and slide out the axle.
Pull the locking key.
Get the 2-9/16" socket and remove the nut.
Remove the hub.
Remove the seal.
Replace the seal.
Put the hub back on.
Torque it down (forgot the magic number).
Put the locking key in.
Slide the axle in.
Bolt it up - 90ft-lb on the axle bolts.
Fill it back up with fluid.
Done.

Did mine last weekend. Been leaking for 70k miles all over the brake shoes. Sure is nice to be able to stop again.
