drop links or any cv joint would cause a knock, not a creak. most probs anti rollbar bushes. a bit dubs 40 or silicone spray will sort it. you will have to remove brkts if you use grease so you can get inside or you will just seal the sides and wont be able to get any sort of spray lube in. use a silicone based lube or it will just dry out and the noise will come back. dont use duck oil.
