Is the rear driveshaft damper actually "optional" as stated by

iPhoneEngineer · 2013-07-28T01:25:42+0000

Hey all—I recently added a 2008 Cayenne Turbo to my garage, and before starting power mods, need to take care of the driveshaft. I was really surprised to read this in the service manual: " The damper is no longer used as of model year 2006. The damper can also be omitted for previous model years." My '08 definitely has the damper installed, and it sure seems necessary (I doubt the shaft would be long enough to just bolt up without the damper in place). Anyone know what is meant by this? Any other words of advice I should have in mind while doing this replacement? I found the DIY here, which is certainly helpful :). Looking forward to getting to know the community here!
