I used a hand wrench and the nut got stuck about 3/4 way off. Had to cut the nut off and then tried to use a stud extractor on the stud and that is when it snapped.
This happened on my 4900 mile de5, even after soaking. I hired one of my techs to extract and it took awhile to get it out( in chassis) without damaging any threads.
Hope you don’t mind me sharing but I had a busy weekend installing a tsp downpipe, PRL front pipe, PRL rear mount, hondata can flex, powder coated PRL front strut bar and PTP turbo and downpipe blankets this weekend on my de5.
