2003 Honda Element Q&A

2003 Honda Element Question: Does anyone with a 2003 Honda Element have a rear suspension knock,noise?

Have had what I believe is a rear suspension noise for the last few months which my mechanic has tried to but been uanable to find the source of the problem. The noise is a loud knock when traveling over the slightest bump. According to the mechanic he can not see anything broken. I'm wondering if there is anyone out there with a similar problem or knows of a solution? -
