bad vibration on 36 sedan

[alanwoodieman]

1936 has a bad vibration at 45 mph, literally makes the steering wheel shake. Push in the clutch and it almost goes away. Jacked up car ran it in gear up to 50 mph with not any real vibration. I was advised it could be pinion bearings--question what noise would those bearings make? and could they cause such a vibration. Yes I checked the tires for bumps, knots, etc
