I did a search and found some good stuff but i did not completely understand. Some said to place the car on jackstands on the sub frame. doesn't that defeat the porpose. Don't you want weight off the sub frame? I guess I don't get it. Where would you jack from? /support.

Here's a good thread:

And a post that explains where to support and jack:


It's not too bad of a job. Make sure you spray your body mount bolts down real good with penetrating oil a couple of days before you break them loose. The longer the better if you ask me. Like what was said before, only do one side at a time so you don't lose the subframe alignment. I broke the bolts loose before I jacked the car up on one side. Rest the body on jack stands with a 2x6 in between the body & stand. If you're floor pans are rusted, I wouldn't try it. But if they're solid, it's no problem. Once the body is supported, use a floor jack to put some pressure on the subframe. Now you can remove the bolts. Slowly lower the jack until you have enough room to remove the bushings. Slide in the new bushings and raise the frame back against the body. Start your new body bolts and only snug them. After that, you can remove the jack stand(s) and lower it back on to its suspension. Torque the bolts down. Repeat for the other side. You can check your frame alignment through the center mounts. There is a gauge hole that will align with a hole on the body when correctly aligned. One thing to note: You may have problems with the cage nuts spinning trying to loosen the body bolts. Hopefully this won't happen but be prepared if they do. This will definitely create more work. Hope this helps!

Thanks Dave
