Hi all. I was driving my 65 fb to work yesterday and ran the speed up to 80 or so and got a bad vibration up thru the shifter. I slowed and it followed me down to 50 or so and went away. I eased the speed back to 70 and it started to come back. I crippled in to work and home but am not sure what I am facing. U Joint setting up drive line vibration? Trans trouble? It was 10:30 when I got home so was looking for thoughts for the diagnosis game tonight. The trans is a toploader 4 speed, the vibration was very rapid making a groanish noise. Any thoughts appreciated. Thanks for the help. Steve

How are your back tires? Did you maybe lose a balance weight?

just happened all of the sudden? Made any change in the driveline rotating parts? Something is out of balance.

tires

You will laugh but The wheel tire combo has no wheel weights. The wheels are vintage troque thrusts and required adhesive weights. I work at a vocational school they mounted the tires up went for a drive there was so very little vibration I just ran them. The combo has been in use about 10 years and 20 thousand miles.

yeah, this could be several things. Since all of them attach to the transmission...and the shifter is mounted to the transmission you will get it all. Tires, Ujoint, trans mount, etc.

Try getting them balanced, see if that helps. Thats what I would do.

Could have lost a draveshaft weight. I'd check that if it's something that came on all of a sudden. If you did, I'd change the u-joints as well once you get it rebalanced, as well as a new rear seal in the tranny tailshaft.

This weekend

This weekend might allow the time to get the thing up on stands and give it a real looing over. I twisted up shifted to nuetral and killed the motor the other night but that did not make it go away, not that I thought it would but was hoping to gain a hearing perspective. Hope its not in the trans.

If the vibration is only coming through the shifter rather than the steering wheel or whole car, then there's a good chance it's a U-joint or at least driveline related. It would be a good idea to get under the car and check out the driveshaft/differential slop(if any).

The Mopar steel wheels on the car now have center holes larger than the stock Ford hubs. The tires were mounted and balanced by a local shop with a good rep. I thought the taper-seat lug nuts might center them alright, but they did not. I had to make some "hub-centric" rings on a lathe to properly center the wheels. Works great now, but when it vibrated, the whole car would shake.
