T-Series Scuttle Shake/Vibration

[PAUL161]

Approximately between 3400 rpm and 3800 rpm running around 65 mph, I periodically get scuttle shake. I used a dial micrometer checking the drive shaft and found on both ends the shaft is 012 out by the weld on the same side front and back, the center is measuring 025 out also on the same side, other side being 0. Never dealt with such small diameter drive shafts. There also seems to be a little side movement on the spline where it goes into the front yoke. What do you think, replace it or that's not enough to worry about? PJ

Weren't you warned about buying the square tires? Sure they look all cool and modern, but still... :grin:

Yeah your right Drew! But I thought they would enhance the looks of an antique car. :highly_amused: PJ

I think your wheels and tires were not done correctly.

It's the tires, they need truing/shaving and then re balance. PJ

[SIZE=-1]The shake is gone. Last two tires rotated did the trick. 55/65/70 mph gives no shake at all. 20 miles on the Interstate and 16 miles on a secondary road produced a smooth even ride with 24 lbs air pressure and no hint of a shake. If the shake comes back in the future, these tires are history. Took a while but for now all's well. PJ[/SIZE]
