front pinion seal

I know this is probably a stupid question, but I can't help it..... I am replacing the pinion seal on the front differential on my 75 CJ. It does not have the crush sleeve, so it looks like a fairly straight forward thing. I have dropped the drive shaft and getting ready to remove the nut that holds the pinion shaft in. So my dumb question is this, how do I lock the pinion shaft to remove the nut. I can lock the front hubs and block the wheels but that seems to be alot of pressure (210 ft/lbs if I read correctly) to put against those hubs. Is there a better way to lock that to remove the shaft?

Please leave off the duhhh, when you answer. I said it was a stupid question....

A lot of guys make their own yoke holder. I have also seen one you can purchase. Basically a thick piece of scrap steel, cut a hole in it so you can get a socket on the nut, and drill 4 holes so it bolts to the yoke where the driveshaft usually bolts.

Here is one I saw a while back. But you can definitely make a simple tool a lot cheaper.

24" pipe wrench works great.
