Having driven my truck all last summer I had never had it over 60mph.The last weekend before parking for the winter,I drove it up to 65-70.There was a vibation.I'll list what work that was already done to it before I noticed it
front clip is 72 Nova -all parts ok
tires are new and balanced,wheels are not bent
drive shaft has been balanced
This vibration was not in the steering wheel it was in the seat.I think that indicates something in the back.Any ideas that I can look for would be great.Thanks, Boyd | | |

The vibration in the seat sure would indicate something in the rear of the truck.
The rear tires would be the obvious first choice, and easy to troubleshoot...put them on the front.
My money is on the drive shaft. Many times the urge to go the 'homemade' route is too strong, and whoever built the truck had his friend with the big lathe do the work.
If you think this is what it might be, you can use a couple of large hose clamps and do a "okie" balance job on the drive shaft yourself.
I can explain the balancing deal if you think it might help..or maybe you know it already.

Vibration would start at around 45MPH. Keep us posted. | | |

After exhausting all possibilites except new tires, I tried Dynabeads. Worked great! http://www.innovativebalancing.com/gallery1.htm | | |
