LCA bolt stuck!
So I'm trying to take my rear shock off to install coilovers and the bolt on the lower control arm will not come out! The nut is off and the bolt will spin if I put a wrench to it. When I try hitting the bolt out with a hammer doesn't budge! Wtf. I tried heating it, putting the nut on the bolt half way and hit it with a 4 pound sledge hammer until I got tired. Currently letting it soak in liquid wrench and taking a break from this damn thing. Anyone run into this problem??

first off I just wanna say thank god I don't have to live in any rust belt areas like this car obviously does. geez, thats rough. and is that shock so rusted that the coil spring is literally uncoiling? Anyways... I bet a million dollars that the reason that bolt won't come out is because the shock bushing metal collar that the bolt goes thru has become one with the bolt itself. the rust has formed the two pieces together. you will remove the shock and the lower control arm from the vehicle. than very carefully with safety glasses on cut the bottom of the shock off from the bushing housing that has the rusted bolt. than take an air powered cut off wheel and get down inside the control arm and cut the bolt into two or three pieces to get it out of the control arm. than install a new nut and bolt preferably a stainless steel nut and bolt. And it needs to be the exact same size and diameter as the bolt that came out. otherwise it will wollow out the control arm. good luck.

The fact that you can spin the bolt leads me to believe it is probably the spring which is putting pressure on the bolt and not letting it come out. Probably the bolt threads are being wedged against the control arm flange. Did you undo the control arm from the wheel hub? That will allow the strut to drop down once you undo the the three shock tower nuts in the trunk. You can then use a small jack to raise and lower the control arm so that there is no tension on the bolt.

So badblackgs was right, "the shock bushing metal collar that the bolt goes thru has become one with the bolt itself." However getting the lower control arm off was a mission by itself. I ended up leaving the LCA on and grinding the bolt head off. Afterwards I drilled out the bolt until it could clear and repeated on the threaded side. Result i got the first rear coilover on! Fingers crossed hopefully the other side isn't as bad.
Side note: I'm never going to buy a rusty car again after this work out, famous last words "how bad could a little rust be?"

i bought my car from Manhattan and live in Tn so as i have been modding my car all this time, whenever i replace, upgrade, and/or remove a part, i have bought NEW OEM bolts and installed them also so i dont have any issues like this. yes i know its a little more costly but saves me a lot of headache down the road

Was the bolt actually fused? I had this happen to me ,but I used a screwdriver as a "tap" and a hammer to get the bolt out. The compression of the strut made it so it was unable to come out unless force was used.
