I'm presently replacing the subframe mounts and 2 of 3 on the passenger side required cutting the mounting bolts off. I'm expecting the other side to be a challenge also. There are some things rust penetrate won't help.
Question: How do I access the body side of the subframe mount at the firewall on the drivers side. It dosen't appear to be an access opening at the fire wall front to contact the threaded body fastener. I'm sure it is going to break loose like the passenger side.
Thanks, John Lighthart

There's that small square opening on the front of the firewall right in front of the caged subframe nut. It may be hidden by the inner fender brace? (my car is apart right now)... It's not a big hole though, so you may not be able to do much. Otherwise it may be easiest to cut a hole in the toe board. I'm surprised these are rusted on your car. Is your car rusted from inside out? My car is a complete Vermont rust-bucket with lots of floor damage, but I still got all my subframe bolts out with little difficulty. Please use the email icon to email me if you need more information, as I have done a lot of work on my car in this area.

Before you go cutting, have you tried some heat to get things to move? I havent found any nut or bolt that didnt give in to some heat.

When I tried to brake my subframe loose the nuts spun in the cage. I took a small chisel and tapped it in next to the nut in the cage. It wedged the nut in tight and I was able to get it off.

Don't give up on the Liquid Wrench. I started spraying the mounts a week ahead of time, once every night, I never had a problem getting one out, especially the front ones at the firewall. Spray a ton of it on the cage nuts from above in those front ones, twice a day for a few days. Use a good quality socket and at least a three foot breaker bar.
