ok so i washed the car and changed her oil , to only start hearing grindin/rubbing noise from the passenger rear . i took the wheel off and couldnt find anything that had been rubbing. jacked the car up on stands and put the car in drive to simulate driving and no rubbing it only ginds/rubs under load im baffled on what could be causeing this. my rear axel clicks maybe that has something to do with it?
