I have eibach pro lower springs, a whiteline rear sway bar, and the Whiteline endlinks.
I was getting a noise coming from my rear which I though was the whiteline endlinks which I heard they were know for. So I put on my stock endlinks.
I am still getting this rattling/banging noise from my rear. It is not as loud as when I had the whiteline ones on but there is still there.

Anyone have any ideas. I have check to make sure everything is tight and on correct.
I do not like driving it with this noise since it never happened before I put these parts on.

 

Check your spare tire area for a loose wheel lock key or other various tools. Its all metal in there, any loose stuff will make a jingle over a speed bump. Just a thought if youve checked everything else

 

It's the swaybar.
