    I got the Prius Offroad lift kit installed along with all new KYB struts/shocks installed in my 2008 Prius and had it aligned. Ever since then, I have a strange rattling/grinding noise when driving over rough gravel. Best I can tell, it sounds like it's coming from the front driver side. Everything sounds and feels fine when driving on regular paved roads.

    Can anyone identify the sound in the video below? (Ignore the sloshing and squeaking sounds in the background -- I have a water tank on board)

    Maybe you have bad bushings

    @JC91006 Thanks for the suggestion. That lead me to do some searching on YouTube and I think it sounds a lot like the sound in this video:



    He says it's a bad sway bar link. I replaced my sway bar links along with the struts (Moog brand), so that's frustrating.

    Did you also replace the strut tower mounts?

    I got the KYB "Strut Plus" packages with everything included (springs pre-installed), so I think yes?

    Mechanic says it was a loose tie rod nut the alignment shop forgot to tighten down when they did the alignment. Getting it re-aligned now.
