cost for replacements? just an approximate. ever since i lowered my car the old oem ones keep loosening up.... and im tired of dealing with it. could there be another problem?

cost is whatever it cost to buy them. replacing them is free. very simple. what do you mean by loosening up? there could be another problem. could you explain alittle more on whats happening?

when i bought mine 2-3weeks ago they were around 30 a pop.

ya, ill try to keep it in dummy terms...

but whenever i put them on, there was a weird vibration noise coming from the rear on the pass side. i tightened them up and the noise stopped for a while, but south carolina roads are bumpy and over the month i have been down here, the sound is returning, it sounds like the entire assembly re-seats itself everytime i hit a bump. umm... whenever i drive down a somewhat rocky(ish) road, the rear sounds like its going to fall off, it vibrates, and clicks and squeeks. i assumed it was the strut mount again, and thats what im going with now. unless there is a better idea. i wish i could get a recording, but my phone has a terrible microphone.
