They are easy to change, but you need car jack or something else to keep the pressure off the balljoint.
Best is using shock absorber lifting tool.
The 3 bolts can be difficult to gett off if they are rustet so WD40 and sprey it good before taking it off.
Find a big flat screw driver to get it between balljoint and mounting brack.
Give it a good whack with hammer to get it off.
Remember the one long bolt needs to be exact back again with new ball joint otherwise it wont fit.
Sorry for bad English i am from Norway.
Good luck
