Re: Chasing vibration

I had like 15 year old tires that did that.

Thought it was pinion angle, nope, carrier bearing, nope.

Replaced rear tires, smooth as glass.

Same here, 67 Dodge Dart had a rumble that cycled on & off at hi-way speeds. Figured it was something that was rotating until I discovered I could hear the rumble just sitting at the curb in neutral. The transmission mount had lost the rubber damper and there was a metal to metal contact allowed. New trans mount and quiet cruising was restored.
