I feel like one of the lucky ones. Seems to have fixed my vibration for now. I'll have to look to see if they used a hose clamp or not, but feels good.
Mine went in last night and they said it's done. They re-indexed the driveshaft and said the vibration was fixed. Could it be that easy? Should I ask if they used hose clamps? I'm picking it up Saturday, I'll report the results.
I rented a v6 convertible last February in California and it was smooth with no vibration with 35000 miles on it. I'm thinking it's a bad run of parts I'd guess.
New 2016 Owner here and didn't feel the vibration that much with a full tank of gas. I'm at 1100 miles and time to bring it in. Let's hope it's a one and done on getting it repaired.
