I have a leak where the drive shaft attaches to the rear differential. Unhooked the drive shaft and exposed a bolt with a large nut on it. It also has a cotter pin through the nut and bolt, which i have been able to remove. I can't get the nut to loosen at all. I went and bought a socket to fit, but is too wide to fit in the space. I end up turing the wheels instead of loosing the nut. Am i doing this wrong?
