Owner report 11320219 · 2020-04-04 (April 4, 2020)

ON SUNDAY, THE 22ND OF MARCH, I WAS TRAVELING SOUTH ON US HWY 45. THE SKY WAS CLEARING AND THE ROAD WAS DRY. I HAD MY CRUISE SET TO 65 MPH.

My circumstances are EXACTLY as described in a release 12/19/2019 Tech Service Bulletin A002 I experienced the vibration in my steering wheel that caused me to be suspect that there was something wrong in the drive train. Upon further investigation. I noticed that an oil seal was leaking, and when I dug a little deeper, I noticed gears that were broken and shaved down and then stopped at a Kenworth corporate location upon which they told me that I needed to purchase the entire unit to fix it. I then decided that I was going to add some differe…
