ya I was like ah ****, at least my kids are here I can have them grab some cooking oil from the kitchen, lol after a couple tries I managed to get out of it, getting the nut tightened back up was the hardest part because it's facing the opposite direction and so it threads the opposite way i'm glad it was kinda loose taking it off the first time, if the bumper was off it would be a lot easier, now I just need to know how much to torque the engine ground strap.Funny how easy you can put a hand into a tight space but can’t get it back out isn’t it? BTW what’s an rvc sensor?
