does the car drive straight ahead?
if you drive into a curve with more force does it slinger or buckle?
if you grab the wheel on top and force it in and out do you feel a play?
if not just grease the front joints and see what is.

I dont thnk that it is too hard but keep a look on the tie rod ends.
if your the thread of you tires is going to be unequal you need to look closer.
does your steering wheel has free play?
