Well, a week long project really. So here is how it goes. Last Sunday, go up to friends house to retrieve my boat (16' Lund Mr. Pike) figure I will use the Jeep. But, spare tire holder I made was too close to ball. As I moved hitch in, before it could drop onto ball the hitch latch would close from hitting tire, preventing it from being able to drop on ball. No biggie I think, will remove the hitch insert (cat I, with the 1.25" solid shank) and get one with a little drop. OK, you know what is next. Hitch is rusted in. So through the course of Sunday, Monday and Tuesday I beat it in, out up down left right, I heat it until too hot to handle, I soak with copious amounts of PB Blaster and rig a block and two small bottle Jack's to apply push between hitch cross bar and insert. NOTHING moves. Repeat these actions many times, start soaking hitch bolts with PB on day 2.
Wednesday, deside hitch is coming off. 1/2" breaker bar with 2' cheater. Bolt into right frame internal welded in nut actually screws out! Move to left side, 3rd pull it twists off. Bolts through into bottom of stock bumper very rusted, I just saw them off with sawsall.
Hitch is now off. I hook it between grapple forks on Kubota loader with insert chained to grapple. Surely it will pull out now. Or not. Hitch folds up like a jack knife, insert does not budge a fraction.
Order new hitch.
Thursday start drilling out the twisted off bolt. Planning to drill out with 27/64" and tap to 1/2" NC. Run a 1/8th pilot hole up through center of bolt to guide.
Friday, new hitch arrives. Finish drilling out bolt up and through the frame internal nut. Tap the new threads.
Tomorrow will bolt on new hitch.
