I finally made an account on here so I can ask questions. I have an 05 V and the driveshaft coupler needed replaced. I drove it awhile until then I ordered a revshift coupler. I assumed that would solve most of my vibration since my stock coupler was in bad shape. First install of the coupler I did not have washers and did not install the washers which was my fault but the car made noise so I pulled it back on the lift checked it all out and finally drove it and it did not make a 3 mile trip before it tore the three bushings out on the driveshaft side. I got online afterwards to see I missed the washers so I called revshift and they rebuilt it for me. Second round same thing I checked it out put the washers on torqued them all down and half mile down the road I had the same problem. I have read through the articles I could find and no one seems to have a clear answer. Just looking for some help from the wiser.
