I have a vibration / drone whenever I ease of the throttle and the engine rpm decelerates form 2800-2300rpm. It is not always the same but always noticeable.
The driveshaft has been balanced and checked twice, it is perfectly fine and the u-Joints are ok. The rear axle has been checked as well, all bearings are new. Total mileage is around 11000.


Any ideas and I hope it is not to bad ....

Dual mass flywheel

Is that a big issue? How much will it be to have it done?

Do I have to get one of those single mass flywheels to get rid of it?

The Decel Vibration is on most of the Manual V6 cars, I am just going to replace mine when the clutch wears out.

I guess I have to change it prior to the clutch. If I am going to add some more power it needs to be all right.

SpeedyJoe

Is that the flywheel I should go for?

Get a professional opinion first from your mechanic before you start ordering parts.

I just recently had my rear main seals replaced( oil leak)
The dealership also replaced and resleaed my oil pan to be on the safe side they said.

Prior to all of the work they had done. my car had random vibrations while decelerating as you've described. Since they've done the work to my car, the vibrations are essentially gone/hardly noticeable (just like it was when I first got the car)

something must have been "adjusted" while they ripped the car apart to pull the tranny out.
