Knocking under dashboard on passenger side?
Any expert advice here would be great-
Truck-2005 F-150 XLT 5.4L
Problem-Currently when my truck reaches a speed of 45mph+ there is a methodical knocking sound that comes from the passenger side dash. This sound is on the interior and comes from the far right corner of the dashboard.(almost as if someone is tapping with there finger every other second). There is no correlation with anything else being turned on or off that affects this sound.(i.e. air) It simply happens once I reach a certain speed and is not an outside noise. When I slow back down under 45 mph the knocking subsides. Has anyone ever experienced this? Any suggestions?

There has to be a correlation with the speed here....something is causing that knock when I reach a certain speed. It sounds almost as if the clicking is coming from right beneath the airbag. That wouldn't make much sense in regards to speed though...IPn reference to the wheel bearing idea...This sound is strictly on the interior and is unacceptable, there should be no reason that a knocking sound should happen under the dash when I go 45mph+....I'll look into this further and see what I can find.
