I have a 92 525iA.
Last week I heard the clicking sound under the right side (most prolly front). First I thought it was something stuck inside which was hitting the wheel periodically. The frequency of sound would increase as I increase the speed.
I noticed it only when i had my right passenger window rolled down.
Now it's stopped, when I decided to let my friend drive it for me to watch

.
Is it the sway bar link?? If it is, where is it located and how would I know if it has gone bad?

Can it be replaced anywhere or do I need to take it in to dealer?
Thanks for reading.
