Word is that the Antebellum fire was caused by: "oil seal on the hub failed, and the bearing overheated and caught fire, mostly happens on trucks and buses that have the fancy hub caps that cover the hub seal, poor pre-trip on the driver's part", as reported on the TMZ site.

I had leaking stemco hub seals on my tag axle. When I bought my bus in Kamloops, BC and stopped for service at Vancouver the techs spotted it. They said Prevost went to a new style stemco hub seal. Here's a pic of the installed new stemco cover, note the larger red breathing button:
