Funny you should ask. A few nights ago our ceiling fan started chirping so I pulled it down, tore it apart and lubed the bearing. It did no good at all. I've contacted Crossroads and a new fan is on the way.
Sounds like they may be starting to have a supplier problem, our Cruiser is a 2010 also.
I too had mine to start squeaking on our last trip tree weeks ago. A couple of shots of WD-40 and the squeak was gone. I also have a 2010 model. Next trip is on Labor Day weekend and I'll be sure to listen closely.
