2009 Ford F150 vibration/shutter from a dead stop
Hey guys,
So this problem happens in 4x4 and 4x2, forward and reverse. When I touch the gas and the truck starts to move, there is a slight vibration/shutter that will disappear when I hit about 5km/hr. Tried replacing the rear diff fluid but no luck. A lot of forums are saying this issue is caused by axel wrap, but the axel stays put when the vibration is occurring.
Any thoughts would be helpful.
Thanks everyone.
