2000 Volvo XC70 noise

Suspension problem
2000 Volvo XC70 All Wheel Drive Automatic 97000 miles

There is a very pronounced noise coming from the right side and if feels like it is the shock or spring. It is a noise like a rusty spring but it only is very noticeable in cold weather when you hit a bump or go over a rut. When the outside temperature it is over 60F there is no noise. Car seems to run fine straight and smooth at all times. No jerking on the steering wheel at any time.
