torsion dampener

Hey all my 05 rckt is making a terrible grinding noise coming from the left side of the engine, it only happens when I take off and start to accelerate. I'll let off the throttle when I hear it, it goes away immediately and then I can continue on through the gears up to cruising speed with no noise. im thinking its the torsion dampener bearing... any thoughts.

I wish I had some solid insight for you. I am a bit of a novice myself mechanically. I do know a friend had to have that bearing replaced on his '05. Seemed like a big job, but I have had the front cover off of mine to check the detent spring and replace my clutch. Not insurmountable. The technical manual is pretty good.

What I do know is that you should get to it quickly. A bearing failure could cause more damage and cost more money if allowed to get worse.

Does it do it when you apply the same load (torque) in other gears while accelerating or downshifting?
