Grinding "whirring" sound
Every once in awhile lately I get an expensive sounding grinding whirring sound from my right from wheel. It seems to happen at random times and is only noticeable over 20mph. When I stop it goes away, but today it started back up again. Then I pulled over, backed up a little and it has been fine ever since. It has done it 3 times, the first time when I hadnt even though of 4wd and the other 2 times when I had recently used it and went back to 2wd.
