Scraping Sound After Ohlins R/T
I had new Ohlins R/T installed on my E90 recently. Everything has been great aside from a scraping sound I'm getting on large smooth dips or bumps on the highway. It seems the sound is only when the suspension compresses and briefly creates a metallic sliding/spinning sound. I'm fairly confident the car is not scraping on the ground since the Ohlins are set to stiff and ride height is set pretty high, about stock. I'm wondering if it's the driveshaft scraping the heat shield since the center support bearing may be on its way out? Or maybe something else? Any ideas or insight would be appreciated. Thank you.

Could be driveshaft on heat shield if it was disturbed, also check rotor heat shielding on the hub and look at the fender liners to make sure tires aren't rubbing. That typically isn't a metallic scraping sound though.

Check your rear tire's sidewall and see if there are any scratch marks. The rear bumper cover might be touching it on dips. Has sort of a metallic slicing tone to it.
Also, where the rear bumper meets the fender there is a little bulge in the fender liner that might be touching your tire on dips. I'm talking from an e92 pov, things might be different down there on an e90. |
