I'm trying to change out the rear shocks. I'm having trouble removing the lower bolt holding the shock in. I can turn the bolt using a 4' breaker bar on the bolt. I'm also using a wrench on the nut. (Yes, the nut has a metal bracket holding it in, but I'm using a wrench to back that up and ensure the nut doesn't budge.) When I turn the bolt using a breaker bar, the metal sleeve and rubber bushing going through through the shock's collar rotate. I've concluded the metal collar has fused to the bolt. When I continue to turn the bolt, the bolt doesn't retract. Rather, the lower control arm bracket that is holding the shock's metal sleeve and bushing expands. The metal bracket that is holding the nut is also expanding outward so that it'll no longer hold the nut. It's insanely frustrating!

I've hit the bolt with Liquid Wrench many times. I've wailed on it with a hammer and a cold chisel. No dice.

Has anyone encountered this scenario before? I'm about to pay a mechanic to cut the darned bolt out and remove the shock. However, I figured I'd first try asking if anyone has encountered this and how they fixed it.

Thanks!

Lots of people! Try putting a long pipe on the breaker bar for more leverage.

Can you get a hand grinder up there with a cutting disk on it and just cut the bolt off? The fastener should be easy to replace. If you get the bolt free from the nut you can then cut the head off, pound it back in flush, and remove the shock.

I used a small sawzall w/ a metal blade to cut mine out. did not take to long but it was easier and caused less damage then using the grinder/cutting wheel.
