I have 2009 Puma I was going to rotate my tires and re-pack all the bearings and found the driver side on the trailer front tire was wore down big time. All the other tires are fine, any thing I need to check to correct before I buy a new tire? I measured the middle of the spindle and compared to the back its the same height. I lifted the boat in between both wheel on the frame, so the axle is completely free.Could the wheel be bent and wear on the inside? Need help thanks
