Not a problem at all. When you drive in 2wd, you don't even know its there, because it isn't moving. You do it right, and even when you're in 4wd, but cruising (snow on the road, etc.) it vibrates a little, but not much. I've run mine at 50mph with no issues on I-80 coming over donner summit in the winter before I pulled over and unlocked the hubs.
