Made it to 300K on a Durango. Asked about a rear seal when the trans was done at 175k and was told it was fine. Still had original timing chain on it even after doing several water pumps and thinking it should be replaced being this far in. Good idea on freeze plugs. One behind trans looked bad when I parted it out.
I bought it last year with a hundred and twenty two thousand miles. It does have a small rear main leak. I don't want to pull the motor but every fiber in me says if I'm going to do it right to pull the damn motor... Damn it! LOL..
