I have a 2010 forester with a manual transmission. It has a really bad clunk or jump in the suspension when you turn in a parking lot or a parking space, either direction and in forward and reverse. I thought it was a CV joint so I changed both axles and both front wheel bearings since I was in there. This solved nothing. This is a similar clunking like a posi-traction reared with new clutches but is more violent in the front. This happens after the transmission is warmed up either by driving 5 miles or leaving it idle for 15 minutes. It is fine on a cold engine/transmission. It also developed a whizzing sound from the transmission or drive train after warm-up, noticed on de-acceleration. The sound is like the gears are meshing, just bad, just enough so you can hear and feel it. I also drained and changed the transmission/front differential fluid. None of this solve the issue. What could it be? Any advice?
