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?
That nut requires several hundred pounds of torque to tighten, so will be hard to remove. I use a 48” pipe wrench across the U-joint to remove and tighten, so grind on your socket to fit properly to prevent an accident. Get a proper wrench to remove.

Doesn't take much time to make a jig to hold the yoke with a few feet of flatbar. Just need two holes drilled the same distance as the u joint strap holes, rest end of the jig on the floor. Makes the process a bit easier and safer.
Bought an impact driver and the nut came right off. I also removed the washer, but now am stuck. I can't get the yolk off to get to the seal. What am i doing wrong?
