So heres my question my 1986 GMC suburban starts to shake at any where from 25 to 35 mph. I don't have any idea what the problem could be. Im not mechanically oriented. Seems like its not anything to do with the motor because when at stop my vehicles sounds fine. Thank you

A lower speed vibration such as that makes me want to check the tires for a shifted belt ( will notice this at even slower speeds), a u-joint problem ( will usually hear a clunk when put inn gear) or a loose steering part.
