The humming i'd be 100% on is the tyre rubbing on the strut.
It could be that your power steering pump has stopped working, this would give additional resistance to the acceleration/deceleration of your car.
Remember when you turn your wheels the strutt moves aswell so shouldn't clash.
As said above, check the inside of the tyre, if it is rubbing then this needs chanced ASAP
If your wishbone needed replaced and they didn't replace the bushes i would be very very worried about the state they have left your car in
