after driving on a gravel / stone road I heard a metallic screeching sound that screeches at low speed and tapes off at high speed. After doing some research it appears I have a rock in my rotor shield scraping off the rotor. I'm 196 miles from a service center. Should I take it to a local mechanic? Are the giant lifts it the shops pretty standard and wouldn't have any difficulty with the lift points? And are the lift points similar to other vehicles? No one in my area has ever worked on a tesla before.
