I tried impact wrench, long breaker bar with extended pipe, PB buster, turning counter-clockwise (left loosy right tighty) and it just didn't bother. I thought it was crossed threaded so I took it to a mechanic, it took him all but 30 seconds to take it off and only 40 mins to install the rubber on the CV boot. I didn't see how he took it off, so now I tried again to remove it, and still not having any success. So What am I doing wrong here? I borrow the 1/2 inch socket and 1/2 inch breaker bar from Autozone. I notice that all impact sockets are black, the one I borrow is silver...does it matter? I really gave it all when I turned manually. With the impact wrench, the socket just spins around the nut and i made sure it fits tightly too. So...any help?
