Yes, you can now get all the control arm bushings seperate.... Even the cross axis ball joint which is located at the rear knuckle lower control arm (rear lower control arm with bad cross axis jt used to require $$$$ entire control arm).
I believe you are currently limited to mevotech brand (last on my list of favorites) for the front lower forward bushing.
A couple points:
-Ford control arms are $$ but the bushings last longer and paint is more durable
-Ford typically does not offer bushings seperate other than rear upper rear bushing assembly and swaybars
-When tightening suspension bushings, weight of vehicle needs to be on system, otherwise you will shred the new bushing fast. Part should have details on if this is reqd.
