Sorry for the fuzzy pic-camera misbehaving.

 Finished planting corn and looking at rear of tractor I noticed the tires are a little closer at the top, may be hard to tell from photo but  (3" to be exact) closer than they are at the bottom.  Maybe it has been that way since I got it and I never noticed it. 

 It that something that happens over time normally or am I looking at new rear axle bearings or something? Can't tell anything out of the ordinary when planting or running down the road.
