I only hear I from the front passenger drive intermittent either clunking or flapping noise (not sure how to describe it) but as soon as I hear it, my reaction is slow down and it went away. As long as I keep the care under 65, I don't ever hear the noise. Only when I go 65+ and it is intermittent. It doesn't happen all the time. There's not vibrations or any type of shaking, just the noise. Is this the problem with the axel, boots, bearing, etc...? I don't mind replacing the Axel just want to ensure I am fixing the culprit of the issue. TIA.
