    I think the trans crapped out and he's wondering if he should rebuild the t-case while he's at it.

    My thought is no. It probably doesn't need a rebuild yet. Unless you're getting funky noises, the case popping out of gear, or a sloppy chain...don't mess with it. If you're leaking fluid out of the front or rear ouput, it's just a seal that needs replacing.

    Ya,I think you are right. He might be better off getting the whole thing from another truck or the bone yard.

    I you are taking it out yourself you might as well crack open the case just for a look. No reason not too. My 208 seemed to be in good working order, but when I popped it open I had some bearings and stuff that were toasted.

    Pop the case and look of an excessive amount of metal on the bottom of the case near the magnet and also look for excessive chain slop. If everything is ok then it will cost you $3.99 plus tax for some RTV to seal it back up. If it is torn up it could save you alot more to get it fixed now instead of having it break somewhere in the middle of nowhere.
