94 Suburban Front Shocks

1994 Chevrolet Suburban C1500 5.7l Front shock question: and that is, given the configuration of the control arm, I don't see how I can get a wrench on the top shock nut while holding the shaft steady with vise grips. Given that both nut and shaft ar recessed, I don't see how I can get any leverage to break the nut loose. (Please see pics). Any advice guys? Thanks, Pop

If you have access to an air compressor and an air hammer with a long-sharp cold chisel, you can just place the chisel next to the stud and hit straight down and shear the nut into two pieces.

Great idea. I have a compressor, just need to buy the air chisel. I'll let you know how it goes!

I just hit them with an impact gun, and if need be pull the bottom around a bit while I'm doing it. Sometimes just holding the socket with your hand tight enough to make the impact gun "hammer" will take the nut off even if the whole thing is spinning.
You can cut the upper protective sleeve (sometimes plastic, sometimes steel) and expose the rod and try to hold that with vise grips. It's hard to get substantial grip like that.
Heat is always a powerful ally on stubborn fasteners...
