Hey everyone. Went to to go remove my front struts today to replace the monotubes with a new set, and I couldn't get the upper retaining nut off. I was able to completely remove the strut assembly from the truck with no issue, but the retaining nut and the bolt both spun together while trying to remove them. The gap they are in is so small, I can't get a wrench on both the nut and the bolt. Does anyone have any ideas? I'll cut it if I have to, but I'd rather not. Thanks ahead of time!
