I have a 91 f150 ext cab short bed 5.0 auto 2wd.
My problem is at about 45 mph and up it vibrates pretty bad coming from the rear, it just started a couple of days ago.
I have re-balanced the wheels and that didnt help and tires are like new.
Could it be a mount or something broke? It feels like when you go from reverse to drive or vice versa the tranny moves aot and it makes a clank, but not like its in the tranny but the tranny itself is moving??
Can i take it somewhere and somebody could look at it for free?
