I bought an aftermarket rear driveshaft to replace my chewed up factory rear shaft. While removing the factory driveshaft, the factory pinion flange only rotated a little bit, so it was reasonably easy to get the pinion nut off. Now I have a pinion seal leak, and I'm trying to replace the seal. While removing the aftermarket yoke, it seems like the yoke just keeps rotating, so I haven't been able to get the pinion nut to budge at all. I'm guessing this isn't normal... so I'm just looking for some guidance.

Worth mentioning that on the initial install, I stopped tightening when I heard a metal clunk sound, however, the Jeep has been driving fine. I'm wondering if this has something to do with me destroying the crush sleeve or bearings or something. There's some yoke in and out play as well...

This is what it looked like when I first installed it.

I am not sure I follow completely, but this tool bolts to the flange and then you can put a breaker bar on it to hold the pinion flange from moving. I let it rotate until it hit the ground and it held the pinion flange from moving until I got the nut loose.

Oh, guess I didn't realize how normal it is for the flange to rotate. Cool. I ordered one similar to that.

There is nothing there to keep it from spinning, assuming the gears are in good working order, unless either the tires are on the ground or something is used to brace it. Even w/ the tires on the ground the entire Jeep will more than likely shift and move back and forth. I have seen the nut removed w/ impact gun w/o bracing, but w/ a breaker-bar... good luck, as you have found out already.
