Testing The Techs' Skills Right Here! HELP
Alright guys, here is the problem. I have a 98 C230 on staggered 19s and a 2.5"+ drop, but that's not the issue. I have recently added some sound inside the trunk, and since then, sometime I head a thumping noise that gets distinctly repetitious the faster as I am going.
Here are the catches: it is not rubbing on anything inside the wheel well. If I am driving, and I slightly engage the parking brake, it goes away, temporarily. It eventually comes back at which point I must do this again. Here is another strange catch: After I lower the car after being jacked up, the car does not make the sound. I wonder if perhaps this could also be a driveline issue?
Here is a pic of my car before the sub. My car now is around 1/8" from tucking rim in the rear. If it helps at all, the rear is a 19 * 9.5 ET38 with a 255/30 19 with Dunlop SP Sport MAXXs. Thanks!

same problem happened with me what you need to do is change your lug bolts they are to long and are catching on the rear parking brake adjusters I think this may solve this I went through this problem also!!!

Problem is I have gone several thousand miles on these wheels with no issues, why now?
