They aren't so difficult that you can't do it yourself, either.  I've
always done my own front end parts replacement.  I can even do a decent
alignment at home, if necessary.  Both the upper/ lower balljoints and the
a-arm bushings are relatively easy to do for the average DIY-er here.  While
the a-arm's off, take it to a welder for a couple of tacks on the bushings
per Bentley instructions, if you can't do that part.
   IIRC, all 4 parts can be replaced without requiring an alignment, but if
needed, it could be driven to be aligned, after all parts replacement work
is done.
