Thanks for all the input, gentlemen. I checked my service bill and the part number for the seal is skf 23000. Unfortunately I don't know how to upload the photo. (looks somewhat like a ball joint cover) Will do some homework on all the suggestions. Again, thanks to all....will keep you posted....Keith

Is this part available from a Canadian source? Thanks for the info on the seal.

I thought that my rear output seal was leaking and replaced it twice and it still leaked. After cleaning it up multiple times to try to figure out where the oil was coming from it turned out the yoke was leaking where the plug in the end is pressed in. I tried silicone, epoxy and other stuff but had to weld the plug in to get it to stop leaking. Might want to check into it

I'm not sure. At the local level, a good transmission shop would probably be able to source it for you. But that same shop would also be able replace just the bushing for you as well.

This is a very good point and one that I forgot about.

However, if the OP replaces the seal and the leaks stops for a period of time, it isn't that leaky plug.

I appreciate all the input gentlemen. My biggest disadvantage is having to drive long distances to access someone to work on it, the joys of small town living. I will look into each of your suggestions. I'm wondering if the seal is lasting a year and a half, is that normal wear and tear or indicative of another problem as pointed out by you all? Thanks again. At this point, I am inclined to replace the seal and move on but wonder whether hidden damage is being done by missing something.

That is not normal wear and tear for that seal. That seal is failing prematurely because there is too much run out on the slip yoke because it is not being stabilized well enough because the bushing is worn too much. The seal has some give and can deal with a little run out but over time, it will fail as a result.

There isn't really any other damage being done other than ATF undercoating your truck when the leak starts.

Appeciate that....actually there is little fluid on the undercarriage, just drips onto the garage floor after a long trip. Will look at replacing the bushing or tail piece in the future.

Quick update, bought the tail section from Torque King on Amazon.ca. The price was cheaper but with shipping, still worked out to $250 CAD. For any of you American friends, Walmart sells this item for $119 USD, but still sources it to Torque King. Contacted my mechanic who will have no problem r&ring this. So I will have an extra on hand should I need one in the future, or sell to anyone. Again thanks for all your input and wisdom.
