You didn't check them when you did the galley gaskets? They would have been making noises then. At least it was something simple.

I actually replaced all three when i was putting the front cover back on. My mistake was i didnt use OEm for the pulleys which i knew would bite me in the ***, and it did. Thats autozone quality for ya. Thankfully i went OEM with everything else it was just i needed them in a pinch and figured they wouldnt fail in two months…

Found out the same thing with my Murano. Except it was a name brand aftermarket kit, Dayco. First the belt ripped after 2 weeks and it took out one of the Idlers. Or other way around. bearing spins but squeeks

Dayco was the brand i got too ironically…. It looked good because it seemed like it was machined well. But i guess the bearing is bad in those. Not sure what the supplier for bearings they use is but ill avoid them going forward.

Ya, I used to alawys buy Gates over Dayco. Unfortunatley, at the time, Rock auto only sold Dayco for my vehicle.

Ironically, today, RA is once again selling Gates for my Murano and the dayco kit is removed.

So I'm wondering if there has been many returns to RA and there might be a Dayco manufacturing issue?
