Help with metallic rattling

[Trillyhayes]

Anyone have any clue what this could be? Happens when going from a stop, or randomly at low rpm’s, seems to be worse going around a turn. Sounds like from the front near the tires but I can’t really pinpoint the origin.

Hoping nothing major but can’t really put my finger on what could cause it.

Thanks!

Belt tensioner has gone south. Replace it ASAP before it shreds the belt!

It's a common defect... not surprised since it's so hot right now

expensive from the dealer... if you decide to get aftermarket, and want to get one that's the "same" as the one the dealer sells, INA makes it in Slovakia... there are a couple of aftermarket brands that but it's hard to say if it's the "improved" part mazda sells
