My rear-end's input shaft seal has developed a leak. There was no sign of a leak when I parked the bus last fall and I drove the bus just a couple of times in January when we had car trouble.
Here is a picture of the leak:
I've got a 1977 manual for Eaton EA-104 truck axles which appear very similar if not identical to what I have in my '89. The repair looks pretty straight forward but I have a couple of questions for you guys:
1) I'm planning a trip next month, about 300 miles round trip. I plan to have this leak fixed before then, if I don't get to it should I cancel the trip?
2) Where can I order a seal online? for that matter, is there a good all-round online source for bus parts?
