I have a 2002 Forester 5 speed AWD. When accelerating from a dead stop, letting out the clutch pedal, it frequently shakes the car like it is possessed by demons. I combat this by revving the motor a bit and/or double clutching. It does not do it once the car is moving. Also, it does not occur when the car is cold and gets noticeably worse after it has been driven awhile, fairly consistent then but still somewhat intermittent. Once the car is moving there is no sign of it, even accelerating heavily in upper gears. No bearing noise. Clutch was recently professionally replaced.
Crawled under the car to check u-joints and drive line coupler. Only thing I could find was the rubber mount in the center driveshaft bearing coupler had a little play when I tried to twist it (very little but enough to see). The shaking feels like it starts in the tranny area but quickly transfers to the back/differential area.
Any ideas what is causing this and how to fix it? Thanks, Joe
