Squeaks over bumps is usually caused by the swaybar bushings. On early 203 C-classes MB offers upgraded bushings and bushing brackets with dust boots on them to keep the grease in and the dirt out. MB has kinda a universal paste that can be used to grease up alot of stuff on the chassis, but it's damn expensive. This is what I apply to all the swaybar bushings I can do. For the rear, there's no updated parts available. But a good greasing of the bushing will usually fix any squeak caused by it.
A high pitched clicking noise is usually caused by a worn out swaybar end link. Once again, there's an updated part available. Newer style endlinks are available that usually last alot longer.
And lastly, for clunking noises and sometimes even squeaks, it's very common for the front thrust arm (or cross strut - many people call it many different names) bushings commonly crack, and leak all their fluid out. Sometimes they can even be mistaken for an engine oil leak. There is an updated bushing available, but it isn't that much better and can still tend to crack.
Reminder, that all the stuff I just mentioned are for non 4-matics.
The swaybar bushings can probably be done by someone who's faily comfortable working on their own vehicle, as long as you know how to get the right parts that you need.
Once again, the endlinks can also be done by anyone who has a basic knowledge of what they're doing.
The thrust arm bushings on the otherhand, by be rather difficult. The thrust arms have to be removed competely, and the bushings have to be pressed out and in.
