I have some vibration in the drive train that starts at about 85 MPH and seems to quiet down a bit above 90. The vibration causes the shift lever to “buzz” in that range. The vibration is there whether I’m under power or coasting.
My first thought has been – balance the drive shaft. Was curious as to what the collective thought – Could this be a bad Flexible Coupling? Comments appreciated – Aaron |

Aaron,

Aaron,
A frequency specific vibration can be caused by a few things, with the driveshaft being a possible cause. I would start by carefully inspecing the rubber coupler...Any signs of cracking? A 360 degree view is essential. -Driveshaft balance...Possible (see next step) -U-joints...Loose or binding? -Trannission mounts...Loose or deteriorated? -Driveshaft alignment... -Lastly, unlikely but possible, differential bearings... This is the order in which I'd approach the problem. Hope this helps! Regards, David |
