Clunk noise from front right wheel, disappears without end link

Everytime i go over small bumps at speeds with only my front right wheel it makes this clunking noise, like something is loose. I read on this forum that it probably is the swaybar endlink that has gone bad. Since its cheap to replace it seemed like a good place to start. I also read that its good to test drive the car with the end link removed first to see if the noise goes away, and it did. So i ordered a new one and installed it thinking there will still be no noise, but it came back.

Does this mean that there's something wrong with the swaybar itself, or can it be something else? I have read that i may be a control arm bushing, but it seems like that the noise wouldn't have disappeard when i drove without an end link if that would have been the case.

The car is btw a 2004 320i M-sport II

Did you replace both or just the one end?

Like FCAB's, you have to replace both sides at the same time, for they both have the same amount of wear on them.

Oh ok, i just replaced one of them. So you think replacing the other one will fix the issue?

Yes, because once you have a new one on there, the other is getting beaten up.

It is a general rule of thumb, just like brakes.

But wait, why is the noise still coming from the front right wheel as before? Shouldn't it come from the left wheel if it is like you said?

Definitely do suspension and brake work in pairs.

I have a clunk at very low speeds and only while braking. Thought it was my original end links, so I replaced them with upgraded ones and a beefier sway bar. When I saw that the clunk remained, further investigation showed it to be a tie rod on its way out.

The sound or noise can be transmitted thru the swaybar. It is only a big piece of metal, so if you replace both and there is still a noise, I would start looking at LCA's.
