Steering /suspension issue diagnosis

[mannyo]

I bought my D2 cheap last week,and whilst driving it around have identified a weird issue that I would like to get sorted.

At slow speed on an uneven surface the front left sometimes makes the odd clonking sound. The driveway to the house I rent is a farm track of compressed mud and very uneven.

On a smooth road the car drives very smoothly, however on a bumpy road its almost like you need to constantly apply steering input to keep going in a straight line. Also if I run over a drain that has sunk in the road with the left wheel then the car almost seems to get pulled in that direction and require a small steering correction to keep straight.

I guess I maybe looking at worn bushes or simillar, so any thoughts out there.
