[V8] wandering V8

[Jason Wilkerson]

Gentlemen,
   My v8 has developed a wandering sensation lately.  Let me explain as much as I can - when driving straight it will seem to pull ever so slightly to one side and then to the other side.  It used to pull to the right just a little, which I kinda liked.  I may be imagining things, or it could be windy out - but It has been happening for a week now and I think it is really happening.  It will also seem to 'steer' by itself in a curve.  What I mean by this is that if you are in a long sweeping curve you may notice the car wanting to slightly turn more?  Hope that makes sense.
   Anyway, everything seems tight, has new struts. The ball joints and tie rods are in good shape.  No noises, vibration or looseness felt anywhere.  One admission - last week during the big snow I got out and 'played' in it a little.  After it was over there was ice and ice potholes in the road everywhere - I drove on that crap for 3 days.  Could it just need an alignment?  Or what did I break or knock loose?  Thanks in advance.
