97 cavi rear struts

hello all =]
I have a 97 cavi. while driving (on gravel or not) it sounds as if I am driving down a gravel road. I think it is my rear struts making the noise but I'm unable to pin point it. any ideas?
thanks! jesika

I've got a 96 with the same problem. What it is, in my case at least, is the strut mounts. The rubber wears away then the strut bangs against the bare metal and makes the rumbling sound. Most auto parts stores have them for about twenty dollars each. You can also check www.tirerack.com. They have them there as well.
