Hey guys i finally got everything installed, but guess what again!? i got my car home and it sounded as if there was a knock, now i dont know what it is, might not be anything, maybe just needs some time to adjust i dont know, but i got it done at the dealer, 650.00 it costed me, thats why i dident want to go there, but its done now and done right, well i think, does this knocking noise sound to be bad to you guys, it only does it for like a few seconds and then goes away. what do you think?
