This would happen at a dead stop or making u turns and such. Kind of like two wet inter tubes rubbing together. Of course when i brought it in it wasnt happening bc it happens on hotter days. But luckily i was smart and got a it video. It was some coil, i can get exact name off paper in car if anyone needs. They said soome rubber boot around coil of something swelled up and whe it shot it swells more which was causing the rubbing. I would even feel vibrations in the gas pedal when the rubbing was happening. Anyhow it fixed! Just wanted to put it out there for people in case this helps someone.
