My 65 "A" block 4 speed has developed a bad vibration which kicks in at 35 mph. It does not matter what gear I am in. It vibrates when on the gas but goes away on deceration. It came on about a week ago and is getting progressively worst like something is coming loose.
I checked the U-joints and they are okay. It is not the engine. So I think I am down to three choices. Flywheel and clutch. Transmission. Rear-end.
The 35 mph is confusing me. I have eliminated tires as a problem. If I lost a weight on the driveshaft I missed seeing it. The rear-end seems okay but may be alittle loose. The tailshaft has some play but nothing is leaking.
Any ideas before I start taking everything apart??
