I just got a '88 Camaro 305tbi 5 speed. Problem is once the car is warmed up I get some major clutch chatter/vibration when taking off from a dead stop. When its cold it doesn't do it at all. The guy said he has replaced the clutch and flywheel but it didn't fix it. Also after about 70mph it vibrates pretty bad and shakes the shifter and clutch pedal. I was thinking maybe rear end bearings but it doesn't roar like their bad it just shakes/vibrates. Anyways just seeing if anyone had any ideas I'm thinking a new clutch(maybe it didn't get broken in) and maybe some u joints but just wanted some other opinions before I start throwing parts at her.

 

Ok a little more info on it, above 70mph in 4th, 5th, neutral clutch pushed in and neutral with clutch out it vibrates.

Also I noticed this morning you can hear a bearing making noise with it in neutrul clutch out and once you push in the clutch it slowly spins down. Once you let the clutch out it starts again.

Someone correct me if I wrong but thats more than likely a bearing inside the tranny right?
