    205 or 203 transfer case? May not matter, but the older 205 used 2 piece transmission/transfercase mounts. You shouldn't get the wrong thing if you tell them the year of your vehicle, and that it's 4wd, whether they call it a transfercase or transmission mount. (or both)

    The transmission to adapter gasket is the one side, the other is the adapter to transfer case gasket.

    Sorry..Its a 203.

    Mine are also 2 piece,a big horseshoe on top and a flat piece on bottom,with a bolt going up from the bottom.
    But I need to get the leak fixed first,if I replace the mounts they will just get trashed from the leak.

    Yeah, I wasn't really clear, the 205 mounts total 4 rubber pieces, an upper and lower for each bolt. So sounds like 203 use same/similar setup.

    Not a bad idea to fix the leaks first. :)

    Hey can I just remove the driveshaft and pull the t-case back to replace the gasket or what ever is in between the two?

    you should be able to just pull them apart a bit. if you go that route, i'd recommend using RTV to hold the gaskets to the mating surfaces.

    pulling the t-case would be more work than its worth IMO.

    I dont have a way to pull it any way,so its just pull them apart a bit or have someone do it for me.I will look in the Chiltons [or which ever cheap one I have] and see what it takes to pull them apart.

    here is how to fix it.

    remove both driveshafts. unhook the 4wd shifter linkage and speedo cable. you may also have a side support that needs to be unbolted from the t-case. support the bottom of your trans and unbolt the t-case and adapter from the transmission. clean up the mounting surfaces and install the gasket, I would just use silicone. bolt it back together. reinstall the driveshafts.

    send me a PM and ask how much I want for the bushings you need. I have a set of Poly ones that were installed and then the truck was wrecked.

    THANKS for the info!! :bow: :bow: I copy/pasted it to Word and put it on my desktop. :laugh:


    If I install poly t-case mounts then I would have to put in poly motor mounts too :(
