i have an 8" rear end, but rear end fluid seems to be finding it's way up the axles and out through the housing tube. It has coated my inside of my rim with gear fluid. Is the cause of this usually a bad or going out axle bearing? thanks

I had the same problem, I just replaced the seals. People will say to do the bearings as well, and I prolly should of, but to date my rear end is just fine. [patriot]

ON A FORD 8 INCH REPLACE THE SEALS NA BEARING

1991CHP ON A 8.8 IF THE SEALS ARE LEAKING JUST REPLACE THE SEALS YOU SHOULD BE FINE

Also, go with the obvious...make sure it isn't overfilled. Level surface, etc ...when filling it. Sounds like both the seals and bearings need to be changed. You have to take the bearing collar off anyway...

i've replaced one of the bearings about 4 years ago, i believe it was the side that's leaking. The driver side doesnt leak at all. Which gasket needs to be replaced. The one where the 4 bolts that hold the axle in? or is there another one? if you look into the axle housing theres another one, but it doesnt look like it would seal anything. Remember im not talking about an 8.8 rear end. This is for my 68 mustang.

The one inside the housing really doesn't do squat...it's a oil slinger. If it's there, it's working. Flange gasket is about the only thing you can change.

Huh?????? The inner seal at the end of the tube is the mail seal that needs to be changed. Never heard it being called a "slinger" before.

To OP, change the tube seal, axle bearing, and for the 4 bolt flange just apply a small bead of silicone to the flange if you do not have the flange gaskets and you will be fine.

thanks guys.. i will just clean it up good and rtv the end.

It's actually called a "axle seal", so we were both wrong. There's no mail or tube in it. [Wink]


Anyway, here's a pic of what you will want to change. Axle Seal
More than likely it's part number 9569S at Autozone. Good luck.
