ok so the studs broke on the 94(rear left wheel) i put new ones in and everything seemed to be fine but now i dont think its due to that but when im driving down the road some bumps i go over my car makes a scraping sound (imagine pulling in a driveway and scraping ur front bumper) i also lowered the car before this happened....so i looked under the car the best i could and i dont see anything that would be hitting the ground idk what else to do

 

Sounds like tire vs fender well

 

hmm how would i know for sure?

 

bump i still have no clue what it is, it sounds like metal hitting the floor but im 100 % positive nothing is hitting the ground
