How to tell if a FRONT SPINDLE is bent???

My front wheels are toe’d out way too much. Before I re-align the front tires again (I aligned the front tires about 8 months ago), I want to be sure that none of my front spindles are bent. Tonight, I jacked up my 900xp and removed the front tires and the spindles don’t appear to have any obvious bends or damage. However, I did notice that the arm that sticks out the rear of each spindle (connecting to steering rod) is at a different height off the ground. One spindle arm measures 12.25" above the garage floor and the other side measures 13.5" above the garage floor. I’m not sure if the height from the floor means the spindle arms are bent or not.

Also, I noticed small grooves on the inside of the front rims. Can a bent front spindle cause the brake calipers rub a slight groove on the insides of the front rim?

Also, can a bent front spindle shift the upper a-arm towards the rear about 1" to 2"? Or is that not possible?
