Check the swaybar and swaybar endlinks for loose joints.
IF theyre all tight, Im afraid its your bushings squeaking. Youll have no narrow down which bushing and replace the entire part.
It could be your upper or lower control arms, outer or inner tie rod ends, or your swaybar or swaybar endlink bushings.
if u here clunking your ball joints are going to b bad
i wouldnt be worried about it until your car is pulling to a side...theirs a crown in the road so find a level street
ok awesome,have no clue what to look for here, but ima try to google it..thanks!
also I noticed the sound would exacerbate when its hot outside, like i would drive it in the morning and wouldn't here anything but when i begin to drive it in the afternoon when the weather is hot it gets worse.
A bit of more information i forgot to mention!! when i brought my car into service the rep.told me that something "cracked and slowly started to leak "at the time they said it wasn't severe and i could keep driving it. obviously i don't remember what he was talking about because it been quite a while since I went back to service because I started to DIY oild changes...
thanks guys for all the help!Hopefully I can get this diagnosed soon

See attached pdf on the issue. ignore VIN's. Even the W204's have this problem.

You need upper and lower control arms replaced.
I would recommend against replacing only the bushings because usually the spindle joints (at the outer end of these control arms) are also probably worn already, or if not will wear out soon. Easier to replace the entire arm.
While youre at it, check your sway bar endlinks by holding and shaking it at both ends. If you feel any play, you might as well replace them too.
Other parts to check are the outer tie rod ends. Check for play at the outer end where it connects to the wheel hub.
Trust me, its easier to replace all these at one shot than replace them one at a time, do an alignment and then find out that something else is worn out a few months later. Learnt from experience.
Check the other side too..they usually tend to wear out in pairs.
Good luck.

how about 2005? My mechanic told me I need to replace upper CA bushings. Seems like everything there is still original up to now, 113k miles
He said ball joints (?) are OK. I was thinking about replacing the two control arms instead of just the bushings. So the difference price-wise should be around $100 then?

These cars go through about 4 castor bushes to one camber bush. The camber bushes seldom fail. The bushes are cheap.

I recently replaced both lower and upper arms,
Sway bar bushings, and links.
After further inspection, i finally found it.
The rattle is coming from a loose steering part that is parallel or behind the sway bars. It is hitting the metal plate cover.
Any idea how to fix this?
Thanks

OK, I finally had my bushings done.
The mechanic had to take off the entire thrust arms to do that.
Do I need to check/correct the wheel alignment after doing this?
(the bolts in thrust arms were standard, not from a 'bolt kit')


So if the alignment turns out to be pretty bad, I will have to buy the caster bolt kit then?

You do not have to get a dealer to fit the bolts. Any decent alignment shop can change them. In SA all our tyre shops carry Benz bolts in stock.
The car comes new with standard bolts in the castor & camber bushes. So you need 4 bolts if it has never been touched.
EDIT. If the alignment is bad you will need 4 bolts.
