    I just replaced my CV axles and on the way home I noticed a new noise happening. It sounds to me like a very faint chugging, sort of like a train? I am not too sure what it could be, unless it is to do with my car becoming reacquainted with new working axles lol. Has anyone had a similar noise or some advice? Thanks! Unfortunately I cannot link a video with this thread, so hopefully I am able to in the comments!

    If it sounds like a CD trying to eject constantly, that's the sound of a failing 3 way coolant valve

    If it sounds like "I think I can I think I can I think I can", that's just a Prius.
