So when i bought my jeep a few years ago, it had a constant pull to the right. I just figured it was due to the crown of the road. then i had the an alignment and rotation and it went away completely. a few months later i had the tires rotated again and it was pulling right again. needless to say i had them rotated a few times since then, and every other time it pulls to the right pretty hard and feels like there's a good bit of resistance to rolling.

wtf is going on?

 

You might just need another alignment, wouldn't hurt to take it to a shop ad get them to balance your wheels and see if any of the rims are bent
