I'm currently running full oe suspension, but I've noticed for quite some time now that when I sit in the car (and no I'm not fat, I'm 120 lbs) the car makes a bit of a clunking sound. This doesn't always happen but it generally happens in the morning after the car has had a good night's rest. It happens from both the passenger and driver sides. I often drive with the windows open and I've not noticed any clunking sounds whilst traveling over bumps or making fast turns, etc.; it really only happens getting in and out of the car.

Is this natural or is there a problem?
