mine way vibrating and it turned out to be the inside blower wheel, got a new one for $9 bucks going to put it on today hope the new one is straight.
I did find a mud dobber nest on the outside blades and cleaned it off and it was still vibrating so I checked the inside blower wheel and it has a lot of wobble in it so going to try the new blower wheel today.
