removing pinion nut?

[mjfoster49]

Does anyone have any suggestions for removing the pinion nut on a dana 60? I tried a breaker bar with a 5 foot pipe slid over it, and I broke the breaker bar. I also have a ingersoll rand 2135TI impact wrench and it wont budge it. I tried heating it, but all i have is mapp gas and I am not sure if it is getting it hot enough or not.

I recently had this same prob, old 60 rear rusted, weathered, so on. After racking my brain and trying everything I soaked it in penitrating oil, let it set for 2 days and put the impact to it, after working it around for awhile, tighten-loosen-tighten-loosen, It broke free. I have also heard of people bolting axles into trucks and running the breaker bar from the nut to the ground then driving the truck a couple inches to loosen the nut. never seen the 2nd one done so dont know, seems a little sketchy, hope this helps anyway.

That is crazy that it wont budge. What kind of socket is it? Is it 6 point? I have never had a problem with a pinion nut not wanting to come off. DO you have good PSI behind the gun? Try tightening it up, then loosening it.

I just got it off, I used a bigger breaker bar with a pipe slid over it. Thanks for the suggestions.

You could try shocking it (I am not talking about an electrical type shock). If you have something like a 9/16 punch, you can use this and a hammer to hit the nut, but be carefull not to damage any threads. Often times if you smack a hard to get off nut or bolt with a hammer (brass hammer)or punch (brass punch), this will shock it loose enough to start coming off.
