Re: 72 Blazer got the shakes bad - HELP

Just a thought, we had a 1978 Blazer that started shaking at highway speeds all of a sudden. Knew it wasn't tires/wheel problem, checked drivelines, okay. Opened hood and noticed one of the fan blades broke off. Didn't hear anything, didn't damage radiator or shroud. No signs of exit of blade. Replaced fan, problem solved.
