I have a 2010 f 150 4x4 auto and every so often I get a vibration in the front end when I first leave the driveway. If I put it in 4 high for a minute while driving and then go back to 2 wheel drive the vibration goes away. This does not happen every day maybe 3 times a week. I never had 4 wheel drive with a **** before my other trucks had a lever and linkage. Please help
