So boys and girls how is everyone. Happy Thanksgiving! So I had a Driveshaft/Propshaft put in March of this year. Aftermarket. Junk already! I bit the bullet and installed a Genuine VW Propshaft Assembly with Center Support Bearing today by Autobarn VW in Mt. Prospect IL. Drives great I tell ya! I will never do another aftermarket Drive shaft. However. There is a slight vibration especially at 60ish. Tires have 5000 miles. Rotated today for first time. Re balanced at Discount Tire. Hunter machine. All fluids are recent withing last 6-7000 miles. Rear and Front Diff. and Transfer Case. As well as Transmission at 85,000 miles. I currently have 95,000 miles. Treg runs perfect other than slight vibration. Mechanic admitted no shimming the driveshaft. He actually said I don't know what your talking about. I have seen where some of you guys have had good luck with this. 2008 V8 with Air. Please help! Have a great holiday!
