Hello, I apologize, but it's almost impossible to guess what a knocking noise could be when those of us here who can try and help answer questions cannot hear it first hand by your vehicle while it's happening. There is so much that can be shared by having a technician local to you hear the noise you are noticing -- contact a local shop near you and ask for some help, and I'm certain you will get someone willing to hear the noise with you and help determine the best path to take towards diagnosis or repair. Good luck.
