So i'd say these were messed up to begin with like I had assumed all along.......I am going to try and get them exchanged as they only have 500 miles on them and this problem existed from the beginning. I am not sure how it will go as the truck has been stored for one year which the warranty states 6 months.......I bought them from National Drivetrain not sure how there rep is?


If they are serious about quality control they would WANT them back to see where the problem lies....
