    Hey guys, i have a mid-late 70's (sorry don't know exact date, if theres a way to find out lemme know) 14 bolt FF thats been leaking on my drivers side rear wheel lately. I rebuilt this whole axle and the matching front dana 44 about 2 years ago. I think its leaking from the round, aluminum gasket between the axle shaft and the drum. If i'm correct, can I get this gasket at a parts store or do I need to go to the dealer? Anyone have a part #? Thanks alot..

    I have had a hard time with that outer axle gasket myself.

    Also make sure your inner seals aren't leaking because they will cause the brake to do funny things and pull to one side. I let my inner seal get too bad one time and had to jump on the brakes in the rain pulling a trailer with a ford F150 on it. The leaky drum pulled real hard and sent me into a spin and jacked knifed my trailer and /forums/images/graemlins/k5.gif /forums/images/graemlins/doah.gif

    I had the same problem after converting to disc brakes and i found that the seal on the inside of the hub was leaking.

    Here is the Autozone part number I used to correct it.
    TIMKEN INNER 2081 $3.19

    I used RTV to seal my outers along with the metal gasket. My metal gaskets were kinda beat up when I got my axle and I didn't thing they would seal so I RTVed the metal gaskets and then put it in with RTV on both sides to help with the seals. Sofar so good. I did have one leak a little but I just popped it off and put some more RTV in and it is working so far. (2 years)

    [/ QUOTE ] If that's where its leaking, just RTV both sides of the gasket you have, don't buy a new gasket, that's how I did mine. I would clean everything up, and find out where the leak is for sure.

    Thanks for all the responses, I'll try that 2081 Timken #. I was thinking about just doubling up on the aluminum gaskets, since its really thin. Seems way too thin too offer any sealing properties. As far as a inner seal, not sure which one your talking about. I do remember, from this site, when I was rebuilding these axles about how a groove can be worn on the axle shafts themselves over time, and that can cause leaking too. Is this perhaps what your talking about? Thanks

    The Fel Pro part number for the little gasket is 55350 and they are $1.99 on www.partsamerica.com (checker auto parts). They call it an axle flange gasket.

    I got sick of cleaning RTV off everytime I pulled an axle so I used the gaskets on mine.

    [/ QUOTE ] I was refering to the inner hub seal. When you pull the hub off stand it up on the front of the hub with the drum hanging in the air. You will see the inner bearing in the hub and in front of that will be a round metal seal. You are supposed to change it everytime the hub is removed from the spindle but most people don't, which is why they leak most of the time. The seal must be pounded out and pounded back in, don't hit the bearing like most people do, get a small crows feet pry bar and pry on it until it pops out. Reinstalling is a little tricky, try to keep strait and lightly pound it in with a small hammer. Remember, pull a wheel....change a seal. /forums/images/graemlins/wink.gif

    I replaced mine a while back, so they are still made, and they were very cheap. But like others have said, no real point in replacing them if you don't need too. I bent one of mine. /forums/images/graemlins/blush.gif So I just decided to replace them both.

    No need to get new "gaskets" just clean them, and silicone both sides.
