I was under the impression that it could be unbolted but you' might get driveline vibration. You could theoretically unbolt it prior to offroading. None of the manual MQ's have it fitted.NowForThe5th wrote:I think your question has been asked before and fairly sure the answer was no.

" I work in dynamics and vibration engineering and it's what is also known as a tuned mass damper and is most definitely there for a reason.
It could just be for noise and vibration comfort levels or it could also be for longevity of bearings/gears in the diff, by reducing vibration levels. I suspect the later, and it was probably something picked up late in development and hence the slightly ad hoc nature.
Noticing any difference with or without through the seat of your pants would be quite difficult as the drivetrain is already quite isolated from the chassis through rubber mounts. You would really want to check the change in vibration levels on the diff with accelerometers.
There will be a natural frequency of some component in the driveline which causes an undesirable vibration and the mass damper is tuned to flatten the peak vibration response. If modifying the key thing is to keep the mass the same but the direction of stiffness of the mounting is also important.
The PA also has a big one mounted on the back of the transfer case so it may be to do with the prop shaft and uni joints ".
So maybe 2 reasons it's there for comfort with regards noise vibration etc or mechanical but why mount it so it sticks out under the car facing forwards . From a quick read from where I found the info most owners have smashed the bejesus out of them.

If the auto has multiple unis, the damper may be there to cancel out a resonance created by the combination.
A harmonic balancer type setup on the pinion shaft may have achieved the same result without having the diff dragging its nuts over the terrain.
