rear wheel seal

[rob love]

If you have gear oil coming out of the backing plate or bottom of the drum, then both seals are at fault. You can have a brake grab fairly harshly, which in turn could effect your steering on a panic stop. Conversely, you can have the brake innefective, which again can effect the steering on a panic stop.

If you have brake fluid coming out of the backing plate, then the wheel cylinder is at fault.

Either one of these requires attention. In the military, we would ground a vehicle for either until the repairs were done.

thought so...does any one here knows where I can get that inner pil seal?

It is a Federal Mogul seal number 5751. Ask at your local seal supply warehouse but be ready for sticker shock. NAPA lists theirs as a 31284, which will run you $$136 if you pay full retail.

Best bet is to order online from Mac's auto, where they are only $20 or so. As well, they will have the splash shield built onto them. Some vendors will just sell you a plain encased seal which will allow the leaking oil to go directly to the brakes.

While some will debate the neccessity of the outer seals, I personally use them. For the extra $20 (by the time postage is paid) per wheel, it is nice to have the oil held back at least a little bit.

Hmmm... Duh. Sure lookes like a BB-1175-C to me.
Be aware of the new parts numbering system since Mac's is no longer the Mac's it once was.

While you are at it, the ring, grease retainer snap, BB-1180C may be something to buy two of and toss into the shipping package. FUC-03 page(s) 4,5, and 7.

BTW Rob, I'd be very surprised if Arie had brake fluid running out of his carrier brakes.
I think I can safely say that (with regards to original build) I will be the only one in the world that that could happen to.

Mac's must have read your post and reacted quickly. My new Mac's catalogue which arrived in the mail this week mentions on the front cover that they are once again using the Ford part numbers. Sure enough, next to the seal is now BB1175C
