The bushing sleeve in the eyelet is seized to the shock mount bolt. Nut comes off fine, can't pull the bolt. Tried wacking it, tried WD40, tried enough heat to start to melt the bushing. Braced the back of the nut and used it like a press, just started to flare the shock mount.
Someone's gotta have the secret for me. Please.  Similar sleeve from the other side which came off with one good wack.

Angle grinder, cut the bolt on either side of the shock and replace along with shock.

Use a 4" angle grinder with a cutting blade. An air compressor powered cut-off tool will also work. Pry the the shock to one side, and cut the bolt along the inside of the bracket. Pry to the other side and cut again. If space it tight you may have to cut the shaft of the shock for more room to work.
If the bracket is not bent open you can cut the bolt flush to the bracket and then pry it open to release the cut ends of the bolt. |

air hammer would probably make quick work of that

You likely have weight/force on that shock bolt, it will make them feel right seized. Put a jack under the end and try jacking the thing up just a tiny *touch* at a time. Once you get the jack to *just* take off the force of the spring, it'll be a LOT easier.

if you want to save the shock then shim the far side of the shock against the mount and hammer the head of the bolt [after lubing the bolt well] against the opposite side of the shock. That should break the rust bond and allow movement and penetration of the oil.

If seized, cutting is the only option. I’ll disagree with you there, but acetylene torch isn’t a bad secondary option. If all you have is an angle grinder, have at it. |

I figured I was gonna have to cut it out.
 Thought maybe there was a trick. Gotta get a new bolt first.

Cut the bolt on both sides. Push the bushing out of the shock and deal with it on the bench. This assumes you're trying to save the shock.

In road salt states, leaf springs often have the this happen. If seized, cutting is the only option. If you can hit from both sides with the air hammer. Also heat it up and hit with cold. Also pout some coke on it. Might get in there and eat the rust. |

Air hammer is useless. The entire bolt and sleeve spin freely inside the bushing, and lateral forces bend the flange
The nut comes off easily, too. I definitely have to cut the bolt. I am not trying to save the shock, I was actually trying to save and reuse the hardware, which is not gonna happen. New hardware just arrived, so now I can cut the old bolt. I have a mini-reciprocating saw that should get onto the gaps inside the flange, and an angle grinder if I have to cut the eyelet. And as a final backup, precut ready-to-weld flanges are available if I have to whack the flange off the frame. Thanks for the suggestions, I tried them all except the acetylene torch, and now for the destructive fix.... |

The one time I had one as bad as yours, that's what it was, I just had to fiddle with the jack to get it to *just* take the force off of the bolt, then it came out much easier than I had expected. |

Oh, sorry, there are no forces on the bolt. The upper mount is fully released and disengaged, the shock is just sitting there, can flop it right over against the fender liner. No stresses at all on the bolt, or the eyelet. Just a seized sleeve, spinning happily in the rubber bushing. |

Torch, drill, angle grinder, sawzall, what have you. Or if you have a welder, you can weld a huge honkin pipe to that bolt. Let the heat shock it, and also have a 6' lever to pull on.
