rattle in right front
 

I have recently observed a rattle omitting from the right front of my 73 911. I have lifted the car and looked and have found nothing loose that I can see. My Koni's are over ten years old and I can lift the wheel easily up and down, could this be the source of the rattle? Also, could the anti-swar bar make this kind of noise? any thoughts on this? If the shock inserts are the culprits, where is the best place to buy them? I have Koni struts.:D

I had a similar rattle this spring. I decided to change all 4 shocks. When I took apart the front struct, I found it loose. The whole shock is going up and down the struct tube. I guess if I let it go, eventually the big nut on top would depart and it would be very bad.
