I couldn't agree more, unless a computer does not tell them a code, they cannot diagnose anything and change parts... In my case, I have been tinkering with mechanical things since I was a teenager, (but I am not a professional) I have not come across everything out there, torque tubes included... If I am shy about something, it is only because I understand that certain mistakes can cost thousands and I just don't have the resources to rectify them...Getting parts for these old big trucks is complicated and expensive enough.
