driveline vibration?

[maple ridge]

Hey Guys

Im getting a slight vibration and sound (almost feels like driving over small rumble strips on the shoulder) after I let off the throttle at high speeds (60+ mph). It will only last for no more than a second. My FX has just over 100k on it and this is the first time I've had this problem. Any ideas what this could be?

Thanks all.

first thing that came to mind is wheel bearing, but that would be constant. Since it is related to you taking foot off gas pedal, I would inspect your carrier bearing. I had one go on my last vehicle and was similar in symptoms to what you described. There is rubber in this bearing that if cracked or broken would cause a vibration/noise.

What's up guys , I think I'm having the same problem, it happens while driving in highway at 60mph. It's not a continuous noise , I notice that every time I make a slight turn the noise begins... My first thought was the bearing on the axle , but I didn inspected yet...
