KW V3's creaking noise

s2krazyyy

Hey guys I recently installed some KW V3's and I seem to be getting some creaking from the rear top hats on uneven pavement or going into steep driveways, the noise isnt always there but its enough to make it noticeable. Ive done some research to try and trouble shoot my problem but none have worked. So far I have tightened the top hat nut all the way down, tightened the two 12mm bolts from under top hat and I also tried spraying white lithium grease around the top hat area and every bushing I can find and I am still getting that dam creaking noise. Another question did any of you install the rear top hat sound insulator? I know that might seem obvious, since the KW's use the stock top hats but I didnt think it would make that much of a difference. I think im gonna try and install the sound insulator and maybe spray some white lithium grease from the top of the top hat since I only sprayed it from the bottom when it was loose. Any other suggestions you guys would have?
