When I was at the Prevost shop, I asked them to look at my front brakes since the hubs had gotten really hot. They did not find any problem with brakes, but did find a problem with steering.
What they did was to take off the front tires, and then grab the rotors at 9 and 3 o'clock positions and then tried to quickly turn the wheel left and right. One wheel did not have any play, but the other one had probably half an inch play in it. That problem is still to be diagnosed but if your wheels are not always going straight, I suspect that will introduce a lot of wobble and steering drift.
They also found a bushing for the front sway bar that was deteriorated.
The coach had been driving like normal with no more wander than normal.
So, my point is that if you feel your coach is not keeping down the straight and narrow, you might have something to repair on front end. I will keep you posted when I get that looked at.
