Thanks for the support! We found a dealer in Florida that adds a lifetime powertrain warranty (good at any dealer in the lower 48), but you are right about the standard warranty. My VX is still covered after all these years! Having a long coverage period is nice if you plan on keeping your ride & don't wrench. Looks like balancing the driveshaft helped, but did not get rid of the noise completely. Our mechanic did not want to tear into the rear diff or transfer case until making sure the drive shaft was not causing the vibes on either end. Your old Ironman was a beast Jay. Cece's Proton isn't lifted that much, but the PO did not maintain it very well at all. She's been lavishing TLC and $$$ on it since she got it and it's just getting frustrating. We shall see...
Thank you everybody for your advice!
