The clunking noise is only on cold days due to the suspension part. I am not sure which part that shrinks due to the cold. I live in Fort Lauderdale thus it is quite warm here in winter. One would only get it if it's below 45 degrees.

The clunking noise goes away when warmer weather. There was a fix on this I think it's on vtec.net under prelude section somewhere with some rings insertion.
