Does it feel heavy, light, loose, is it not returning to straight ahead on its own?
Check tyre pressures and condition, Are they the same type and size, is the direction of rotation correct (it will be marked on the side of the tyre if applicable)?
Jack the car up and feel for any play in the road wheel (worn wheel bearing, track rod end, suspension bush).
Get the tracking checked.
Is the power steering working?
