Drop links are fairly easy to remove HOWEVER before going there I would encourage you to have a real good look at your front suspension. This is quite easy to do and if/when you have a knowledge of the setup then you will be in a far better position to understand and diagnose issues yourself.
For the time being forget your specific issue.
Do the following.
1) crack / losen the wheel nuts - N/S or O/S - suggest the side you think is the noisiest
2) jack car up and remove wheel
3) carefully examine exactly what you see regarding the front suspension setup.
You will see a vertical tube (the damper) with a coild spring going upwards from the wheel hub into the top inside of the wing. This damper & coil assembly is generally called a "strut".
At the bottom of the strut you will see that it is attached viat two bolts onto the wheel hub assembly.
The bottom of the hub assembly is atttached to a wishbone (track control arm) via a single swivel/ball joint.
The wisbone/track control arm, which in total takes the shape of a 'Y' is attached to the chassis at two points (the tips of the Y).
Attached to the hub via an integral arm you will find on either side a 'rod' (the steering rod) that connectos to the steering rack.
Having got/recognised all of these the you have the basic minium component requirements of the front suspension setup of a typical car.
The piece that is missing in the above is the 'anti-roll' bar. This is a bar that attaches to either the yoke, hub or strut and connects the N/S and O/S suspension/hubs together.
This is always/mostly linked or connected to the yoke/hub/strut by a rod or link bar, the drop link.
On the Croma the drop link is attached to the strut/damper just below the spring coil plate and drops down to the anti-roll bar, hence its name drop-link.
4) now that you can see how the front suspension hangs together you can do some simple tests yourself to try and identify any loose or worn components. With the hub/suspension hanging freely you can grab it and manipulate it by hand looking and feeling for any floppy parts. It is unlikely you will initial find anything but if you place some bricks under the hub to make a platform about 3 to 4 inches below the free hanging hub then you can place a wooden lever between the brick platform and the hub lower arm and then start levering up and down the whole hub/strut assembly.
In additon to looking for play in joints it is far more important to feel for play. You do this by gently placing the fingures of one hand ACROSS the ball joint/flexible joint whilst levering with the other hand. Any excess play should be easily spotted.
5) Repeat 4) for both sides.
This is difficult to explain but once you get the wheel off and study what is there and think about how it all hangs together then I'm sure you will quickly understand how it all works and where all the up/down and twist/steering movement joint points are and thus where possible play in connecting components could be producing noise if worn.
