Need help removing nut that holds shock in place, I've tried heat, a hammer and chisel... Options

[914 RZ-1]

I'm trying to remove the nut that hold the shock in place. I need to replace the strut.



I've tried heat, but maybe it wasn't hot enough. How hot do I get it?

I'm using an 18" pipe wrench. It's the same one I put it on with. I changed the shocks about a year ago. It will not budge. It's hard to put leverage on when it's in the vise. I even hit the wrench with a dead blow hammer. It's currently soaking in penetrating oil.

I tried using a drift and hammer to break it loose. Didn't budge.

The next step would be to use a cheater bar on the wrench. However, I'm afraid I won't be able to hold it in the vice securely enough.

Does anyone have any other ideas?

Thanks!

Things change of course over time, but the school of thought on this was that you used a pipe wrench to take it off, and the special tool to reinstall.

The issue being that the special tool was not hardened enough and and a really stuck on nut would wipe it out. The pipe wrench will put marks in the nut, but it will get the damned thing off.

I just have a big assed pipe wrench from when I needed to do it.

If it is the big steel one used on Boge's I wouldn't hesitate to use a big pipe wrench. I have them going up to 48" (IMG:style_emoticons/default/lol-2.gif) . But if it is the aluminum one on the Bilstein insert it would only be a last resort action on my part. A pipe wrench offers incredible grip & torque but impact is more effective and inflicts less damage when loosening corroded bolts and nuts. I would try a blunt cold chisel and large hammer before going to the pipe wrench approach. In order for impact to be effective the part (s) need to be rigidly help in place with no way for them to move when impacted. This is where most people get it wrong. A good example of this is when someone is holding the part in their hand rather than in a vice when striking. (IMG:style_emoticons/default/beerchug.gif)
