Hi everyone. I've got my very first Ford...2010 F150 FX4. I mostly love it so far, BUT there seems to be a wierd vibration sometimes driving down a perfectly smooth road over around 40 MPH. Looking at Rear view mirror shows it may be some sort of bed vibration.

Surely this isn't "normal". Have any of you noticed same? Is there a fix?

Thanks!

Welcome!

Wellsir - no road is perfectly smooth. If the body/frame structure did not absorb some of the excess motion, yer butt would be

I suppose you could have a minor whell imbalance issue - that characteristically exacerbates with speed ...

Remember - this is not a 'extruded from a solid block of billet' structure like an M3. It's a body-on-frame, long wheelbase, wide tracked, marginally-trussed bed pick-me-up truck...

MGD could be right...but check this out.

 

Nice find, Sir Shotgunz!

I wonder how many folks check runout like that.

The other thing that just pooped into me pointy head is a slight e-brake drag.

Thanks. MGD: If this is "normal" then Ford should hire some new engineers. I've driven GMC/Chevy for years with nothing like this (Yukons/Suburbans). Yes, at least here in Texas we do have pretty "perfect" roads at least in places...where there should be ZERO road induced (noticable) vibration. Let's hope its something minor like tire imbalance as shotgunz suggests and not a major design flaw.

Thanks again. Anyone else?

How would one check the e-brake drag?

Thanks.

 

When I had this happen I found one hub/wheel significantly warmer (read-HOT, LOL) than the other after protracted running. This lead me to jack up the truck in neutral and slowly rotate each rear wheel - yep, the dragging one made noise and would periodically'stick'.

Not saying this is a new-truck problem (that is in yer future though, lol), but even a misadjusted e-brake cable will do it.

Shotgunz is likely on track here, though.

If you look around on here - more than a few folks report bed shake with no other attendant anomalies to account for it other than simple design.

Good luck sir.

Thanks! I guess the dealer will have to take the first shot at finding it.

Thanks for the quick replies!
