Fiesta 2015 face-lift version, started to make squeaking noise when both front wheels go over a bump at over 20mph. When i go over a bump on only left or only right wheel I don't hear the noise it's only when both wheels go at the same time. 

The sound seems to come from the middle bottom. 

Any idea what it could be? 

Sound like Anti-Roll Bar bushes need a squirt of grease?

I've had this problem on two previous Fiestas and it was the anti roll bar bushes both times.

Proper annoying noise isn't it, as the above fine fella's say....it's the bushes.

First time it happened it was driving me up the wall.   Nobody, not even Fords engineers could work out what it was.   Then a guy from a little backstreet garage sorted it out by replacing the bushes.   However, I now understand that a squirt of silicone grease sorts it out.

Thanks I think it's the bushes too it makes sense why it's middle front, are they accessible if I just remove the wheel to spray them for now till I get them replaced in near future?
