Stuck Pinion Nut!!

[martinm13]

Hello everyone,

I've got a 67 LWB and I'm in the midst of lowering it/replacing all of the old worn out stuff. After coming out to a puddle of diff fluid on my floor one day, I discovered that the seal around the yoke in the rear end is leaking so I went about trying to replace it today. Problem is, I cannot get the nut off. I have tried an impact, let it soak in penetrating fluid, heated it up with the torch, attached a long piece of steel to the yoke via some bolts for leverage and nothing is working. When I cleaned some of the grime off, I noticed that there is a bevel at the bottom of the nut. I'm not sure this is normal as I haven't worked on C10's before this, could somebody chime in and let me know.

Here is what mine looks like:




and here is a picture I found with the nut off. Notice how the nut in the picture does not have the bevel. I am wondering if mine is somehow welded in place...




Thanks
