    Yeaaaaa. You were right.

    after my own further research, it seems as if it’s the needle bearing… I searched ECGS Bearings on YouTube and there’s tons of 4Runner owners that came across the same symptoms. ECGS bearing will probably be my next step. ‍♂️

    Got the exact same thing at 67-71mph did you find out what was causing it? I have ecgs clams already installed so I can rule that out

    It’s the rear diff howl. Pretty common. Mine has been doing it since new at those same speeds. Changed diff oil twice and at 72k miles it’s no better or worse since it’s been new.
