So, the front diff leaks, I think it has for all the 15 years I've had it. It's been dry a couple of times, I'm sure.
I don't think it is the outboard axle seal, I replaced it with the GM seal, still leaks. From the oil/dust pattern on it, it sort of looks like it is coming from the drain bolt. I'm thinking of thread tape there. I've seen the drips on the ground, I've seen them hanging on the bottom of the diff, but I haven't really seen it running down the side or anything.
I've also read maybe the vent tube is blocked, and the pressure inside the diff forces it out, so I am planning on checking the tube and the vent bit coming up from the diff.
I've also read on the old site people slather RTV where the case halves come together. I'm planning on that as well.
Fill plug is stuck, won't come out. Last time I filled through the axle hole after replacing the seal. This time I will fill through the vent.
Am I missing anything else obvious? If this doesn't fix it, I think I'll just have to try to keep up with it, I don't think I'm pulling that diff down for the other side seal.
