Grinding/ Dragging backend

[Snype451]

I get this horrible grinding noise if I have weight in the back seat of my car.

I finnally got rid if my clunk (new swaybar, endlinks etc) but I get a horible grinding/dragging noise if I have people in the back seat and I go over bumps at highspeed or take a turn a high speed.

If I take a turn then it sounds like the backend of the car is dragging. Its not but you would swear up and down that it is.

My dealer says its becuase I have gravel in the struts and I should just go to the car wash and blow them out with the presser washer.

Thoughts or things I can check for?

look at ur inner fender wells and see if the tires are rubbing

or inside your rims they could be rubbing on strut or shock. Sounds like your bottoming out?

I'll stick my head in the wheel well tomorrow and let you know if I see any indication at all of rubbing
