Big bang and screetching metal on metal sound? I have a 94 4Runnner. Today O was urning around on a logging road in the Idaho wilderness. After backing up in a turn around I pulled forward intending to then back up. As I pulled forward a loud 'BANG' followed by screeching metal on metal.

The motor running fine, transmission working I backed up and drove back to camp about two miles. It did not overheat, oil pressure fine but the power steering was gone.

Got to camp looked under the hood to see the fan assembly separated from the motor. All the belts were in tact. What happened? Can anybody tell me what broke. Was it the bracket or something else.
