Abstract: Provided herein are anti-rattle devices, and turbocharger wastegate assemblies including the same. The anti-rattle devices can include an elongated body having a first end and a second end, a first bend, wherein the first bend and the first end define a first section of the body, a second bend, wherein the first bend and the second bend define a second section of the body, and the second bend and the second end define a third section of the body, a first cavity defined by the first section, the first bend, and the second section, a second cavity defined by the second section, the second bend, and the third section, a first aperture positioned in the first section of the body; and a second aperture extending between the second section and the third section. The anti-rattle devices can mate with a turbocharger wastegate assembly and provide anti-rattling benefits.
