Recently noticed my 53 plate (2year old) ST170 steering seems light/loose/almost skidding for about 1/4 turn to the right (only) on the steering wheel, thought it was just me imagining things, but the other day my missus said a similar thing to me about it when she drives. It seems to brake and accelerate in a dead straight line, except when driving steady in a straight line you can get a loose kinda unerving feeling through the wheel sometimes?

Also - the front wheels are rubbing occasionaly into a dip on the inner arch somewhere, could this affect/cause the above or be a knackered strut or something.

Any ideas?
