2020 Ford Explorer ST
19mm bolt, I’ve tried with all my might to crack this off and so has my FIL who has worked on cars all his life.
Only thing I haven’t tried is getting the wrench seated and smacking it with a hammer… is that really the best way? Don’t want to round it off any more than I already have.
There is no room to fit a socket wrench up there.
Get the car at operating temperature then try to remove the bolt
