Thanks Brian,

This might explain why I noticed the noise right after doing a manual leveling of the bus.

When I finish the leveling I leave the switch in the last position I had leveled.

Before I restart the bus I move it back to the ride position, have I done something wrong in this process ,should I leave it in the ride position after I turn off the key??

I will look for your picks and read the other posts. I definitely am not level any longer, will get back.
