Please help my car makes a knocking noise under the car, just from listening on the ground long side the car it sounds like its coming up by the doors around the same area as the cats. I ve been told it could be a few different things, cat, ac compresser, torque converter (etc.). My questions are is it okay to drive Tito a shop ( not if torque converter? ) and what does it sound like ? Thank you for any in put. I've attached a video I took from my phone. I love my car it has a few lil cosmetic problems but ill do all I can to not have to sell it. Thank you again!!!
