2004 Ford Explorer

I was driveing down the road when the truck started swaying side to side it felt like a bad tire. Then all of a sudden we heard a loud thump felt like a tire blew. I pulled over to the side of the road and there was what looked like oil spraying out of the bottem towards the rear of the engine and it stunk really bad like rotten eggs and burning rubber. The truck runs just fine and I was able to get it home buy driving really slow. On the way home driving about 20mph it was makeing a humming whineing noise.
