Just cut the line right where you are trying to loosen it at the rack and then use a socket to spin the nut out! It works really good!
Any way possible!
I have a cutting tool.... it s small little air saw that will cut it in 2 seconds. You could also use a cutter wheel i you can fit it in there. If not, you will need to use a good size side cutters. It may take a bit to cut through it, but once its off, the nut will spin right out with a socket!
Glad to hear you got it!
Let me know if you have any further questions!
