hi all

looking for some help

I have a 2004 TL automatic with 51,000km (canadian car) and when i hit little bumps on the road I get these little knocking or tapping sounds from the front suspension. I had the car checked at Acura (they replaced the front lower stabalizer bushings) but there is still the same noise. i brought the car in again....and they told me all is fine. I was thinking it was the front linkages...but they told me all was fine. All is original and nothing has ever been replaced.

any clue??
