Sat down with the service director at the dealership this afternoon to talk about this problem and other issues with their service at this complex and finally got an admission that the bump has caused problems before including windshields cracking and he made sense that some models of A's have a tendency to crack under torque stress and suggested a type of torsion bar that ties the chassis to the coach at anchor points . That it also helps with the heave one feels when semis go by. Now this is the sort of up front discussion and dismissal I had hoped for to start with. Not denials and belligerence.
I do have pictures of this speed bump some of you have made a circus of, but I need some instructions on how to post them. I'm not pressing the issue now that I know the cause is compounded by structural flaws in the design of these fragile coaches. And what was supposed to be a 4 hour fix has turned into a 4 day cat and mouse ordeal. They said they would order the glass but it must come from Duncan and would be 10 days getting to them. So they taped it up for me so I can make it to our original destination then the insurace will have to cover it then.
I know this has been confusing and suspect to some of you but I got the answers I needed from those who chose to help in an adult way. As for the bump. It stays because the owners refuse to go to that expense says the service director. I should be on my way by tomorrow afternoon with some new knowledge under my belt new calipers pads seals and drive belt............and a list of jack asses to ignore in this forum
