Review on Dorman 935-102 Driveshaft Coupler: Efficient and Durable Black Coupling Component by Scott King

I installed this in my car last week. These "guibo" disks are meant to last thousands of miles, so we'll have to see how they hold up. This washer was slightly thinner than the one I removed from my 1982 BMW 320i. It may have been because the old one has been expanded over time, but I'm not sure. The screws on this Dorman disk are also hex screws. So make sure you have hex bits to attach this thing to. If you only have regular socket wrenches, you're out of luck. I tightened the bolts to 34ft/lbs.
