Before I get started, i DID do a search. I replaced my axle seal a couple of months ago. When i was changing my tires, i realized that there was something leaking (maybe leaking, could not find the source) from both rear tires. Now the thing is, could it just be the old stuff soaked in the brake pads? or is it new stuff. I changed my right rear axle seal but not my left. Any thoughts?

Possibly the rear wheel cylinder in the drum brakes. Mine went bad and it leaked all over the wheels.

Both my rear axle seals went bad and my rear brake pads were soaked and I had them replaced when the seals were done and I bet the other seal is bad too and the side you replaced is the old stuff that collected.

SOB. This sucks! I replaced both wheel cylinders and they are not leaking. I took the drum off and poked the seals and nothing came out. I really hope the other one isnt leaking (in denial)

Check your diff breather. If it gets clogged, the hot air inside the axle can't escape and that can push gear oil out past the oil seals. Also, did you replace both seals on the one side or just the "easy" one?

I replaced the inner and outer seals on only the Right side. I checked the diff breather and everything works ok. Do you think that the hose length has anything to do with it? Mine is kind of long. (probaby a stupid question)

On the hose length, the important thing is that the hose runs upward all the way from the axle to the end. You want to avoid at all costs any "dips" in the breather hose as it runs away from the axle. Why? The hot air and oil mist that comes out of the vent can/will condense in the hose and is there are any dips in the line, the oil can pool there and block off the hose. It happened to me when I used to have my rear axle vent line running up to tee into the front vent line. Gear oil is pretty thick stuff, gets thicker the colder it gets. When mine plugged, I had two axle seals and the pinion seal go out until I found the problem. It took a fairly good puff on the vent hose to blow air through it. After re-routing the line to the rear, I've had no problems since.

Fix the lines, or at least see if they are plugged. If so and the leaking stops, you are set (the pressure was forcing the oil out). If the line is open or the leaking does not stop, then the seals are bad.
