    I have a 203 case,,,,,its leaking out of the rear shaft seal real bad,,,,its like parked in a slanted driveway,with the front of the truck facing the garadge,,,, (driveway slants down,from garadge to street) hasn been started since i bought it a few days ago, and even still it leaks all by itself :doah: ,,(btw its mated to a th350, but i dont think it matters any)


    i was eventually gonna do the 400 205 combo, but i wanted to at least drive it temporarily until i gather the set. Whats involved in fixing the leak? Is it worth it to fix the leak? Do i have to drop the pan?


    Also, if a dont have the know how or the tools to fix it,,, how much should i expect to pay a shop to do it?

    Thanks in advance all!

    if it really is the rear shaft seal, you undo the nut on the yoke, yank the yoke off, pull the seal, press the new seal on, put the yoke on, put the nut on. done.

    Does this require more than a few Craftsman wrenches?

    I dont have any else but some small hand tools man :crazy:

    Probably need a socket for the nut. Its something like 1 1/4" or some where around that.

    When I last did one, the seal was a bugger to pull out using the universal "seal removal" tool.

    Why fix it? I find that my '74 leaks lots of places ... I took the top off, that solved the roof leak, but the tranny leaks (some redheaded idiot put it in, didn't do it right :haha: ) and so I just top her off now and again.

    If you aren't fully tool-equipped, I'd just leave it until you have the tools and time and the weather is nice. '203's are cheap, anyway ... I have a part-time one sitting out in my yard, should you need one (but they are freaking HEAVY!)

    I believe the socket is 1 3/16", you can buy a craftsman for not too much money and grind it to fit inside the yoke. You should be able to change the seal for less than $50 parts+tools, takes an hour or two the first time.
