Default Is there a safer way to get the lower control arm off?

Last winter, the suspension only squeaked over bump;
This winter, the situation is worse, it squeaks when turning left.

So I decided to the replace the lower control arm, sway bar bushing and links.

After searching on the forum, I found that there is a risk to get the LCA bolt spinning with the inside nut, then the only solution is cut a hole on the inside floor, to get the nut welded on the frame.

So I want to ask if there is a safer way the get the LCA off without this risk?

Any suggestion is appreciated!

spray the bolt as best you can with something like PB Blaster to help cut through any rust on the bolt. Do this several times starting several days before you begin the repair. Also work the bolt off slowly, once it starts to loosen tighten it a quarter/half turn then loosen it, this will help keep any rust from getting stuck in the threads and binding on the nut.

If you have an air chisel you can vibrate the bolt head to help loosen it after spraying it.

Seems it depends what area in USA as far as seasons that you have may determine how tough the job will be.

Thanks.
How can I let the solvent reach the nut inside the frame?

I am in NC, it is a 2006 touring.
I wonder how bad it could be.

You may be inluck as I speak from a mixture of salt and other ice melting products used by the commonwealth. You could drill a small hole big enough for a spray nozzle above the bushing to spray the flat nut, then just plug it with a small screw after your done.

where in NC are you? I'm in Raleigh.

have you been under the car to give everything a good look over? If it's rusty and crusty looking you may be in for a ton of work, if everything looks decent it should come apart without too much issue.

Yep. Not and issue on Arkansas cars. Muddy, but not much rust.

Also, using a 1/2 impact wrench may also lower to the chances of stripping the nut or breaking it loose from the weld. Many times, I've found that the hammering of an impact wrench loosen bolts with less damage than the constant pull of a manual wrench. I freaking LOVE my Craftsman 19.2 volt 1/2 drive impact wrench. That dude is stronger than my air impact wrench. And I've yet to find a bolt on a PT Cruiser that it will not loosen.

I am in Raleigh too.

I will take a careful look when changing oil next time.
In my memory, I think the condition is decent.

Thanks for the info.
