front end nosie

On my 98 camry I have a knuckling nosie when I grow over bumps. I've replaced the sturts. The mechanic said that it might be the strut bellow or the strut mount. Does anyone know what this might be.

It's supposed to be the strut mount bracket. I've got the same thing going on in my '99 right now, I hadn't had the time to look really closely into it yet, although I've been planning on getting around to it sometime soon. Also, I've had some people tell me that there is a possibility that some bushings might be deteriorated.
