So first off, im brand new to the world of RZR and just picked up a used 14′ XP4 1000.

Amazing Machine until today. Was doing to basic trail riding with a few whoops and a couple small jumps. Was crusing on the flat and then all of a sudden super loud rattling noise.

To me it makes me think of driveshaft rattling. It sounds like a rotational noise for sure.

It makes the noise in all methods of going forward. High, Low, 2wd and 4wd.
BUT no noise while reversing. We ended up reversing home(only a couple blocks)

Thank goodness had the GoPro recording so here is the sound.
