I recently replace my front differential due to bad bearings. Now the truck drives great when coasting and there is no noise. However, when accelerating there is a vibration that you can feel in the steering wheel, gas pedal and even the floor boards a little. As soon as I stop accelerating the vibration goes away completely. You can feel it mostly around the 2K - 3K rpm range, outside of that the vibration subsides. This vibration issue existed on the previous front diff.
I've searched and seen that others have reported the same symptoms. Unfortunately, none of the treads I read had a solution to the problem.
Does anyone have any ideas as to what could be causing this vibration? I've heard u-joints, but most said that the vibration should exist even when coasting.
I was thinking of disconnecting my front drive shaft and driving around to see if the vibration stops. But I wasn't sure if it was 100% safe to do that in the AWD Moutaineer's. Some threads I've read said driving without the drive shaft could ruin the transfer case. Is this true?
Thanks in advance!
