Hi I changed rear upper control arms really easy but the lower control bolt attached to the subframe on both side are not coming off I tried everything has anyone had this problem or do you know if the threads might be reversed?

BEST ANSWER: Threads are not reversed. It's a shoulder bolt that's rusted. I had to cut the bolt with a small wheel air grinder.
