New lower arms will have the bushes in them, only standard items mind, but cost a little over £20 for each side as a pattern part, not genuine Ford items. You can get uprated bushes for the lower arms, which means getting them pressed in.
It does sound like a lower arm issue, but get under the car and just have a look! You'll be able to spot if something doesn't look right!
