AMAZING!!

Having just read an answer to a post, I learned that there are 2 small bushings on a small extension to the rear lower control arms, which relate significantly to vibration through to body.

Does anyone know about this? I looked now under the car, and I see where these metal extension-stops are. They have about a 1/2 inch of space between them and the two metal extensions connected to the upper part of the chassis.
In the lower pieces, there is a hole - could be to secure a rubber bushing. I have no bushing at all at either side, and I detect that there ius a bit of clean metal on the upper piece where it may be contacting metal-to-metal with the lower piece. Am I missing rubber there?????
Someone- HELP-please advise. Thanks.

Trying to figure out exactly what part you are talking about is hard.

It sounds as if you have some rear subframe mounts that are compressed.

Thanks for respondeing, but I don't think its compressed mounts. Actually, there's no rubber there on either side, at all. The metal extensions (about 3 inches long each-top and bottom) are: lower, extending from the top of the middle section of the rear lower control arm; upper: just above that, extending down from the main chassis frame. It's the same on both sides. The lower extended piece has about a 1/4 inch hole in it; the upper extended piece, none. As I mentioned earlier, I have no rubber on either side - and it looks like the way it functions, when the wheel goes lower - under load or road conditions - the two pieces act as a 'stop' to prevent the car from bottoming out or to control the limit of its up and down movement. They are, again, solid pieces. However, without rubber bushings, they will contact metal-to-metal. By now, you should have an idea of what I'm describing. So-my question again is, should there be a rubber bushing on the lower or upper part? And if so, how would it be described so that I can order the parts? Thanks again.
