If you're doing this yourself, first, you'll need to lower the front subframe.
You'll have to remove both the inner ball joint and outer ball joint from the old control arm and
fit them to the new control arm. You usually need some kind of ball joint puller tool to do that,
or you could just get new ball joints for the new control arm as they press fit in easier than they come out.
You also need some tools to press the bushing out of the old and into the new control arm.
If you can't get or make a suitable tool, dropping the subframe altogether would make things easier.
There are some YouTube videos on this subject if you search a bit.
I wouldn't try to re-use the old control arm bushing. In fact, I'd recommend using a Polyflex ones
since they last a lot longer than the OEM ones, and they position the suspension more firmly and
they add very little extra NoiseVibrationHarshness to the suspension.
Lastly (or perhaps firstly), if you have aimable headlights (Xenons), and if this is the left control arm,
mark the position of the vehicle level sensor bracket before unbolting so you can put it back
in the same spot as it started.
If you're just getting parts for the mechanic, I'd vote for replacing both ball joints and the bushing
along with the control arm. They're probably in the same sorry state as the old control arm.
