Relative movement between the body and the filler helps dampen vibrations in a component when the insert is carried in the component and when the component is vibrated. ## Claims ### Claim 1 A product comprising: an insert having a body defining a cavity that extends from a first end that is closed to a second end that is closed, the insert having a filler held in the cavity, wherein relative movement between the body and the filler help dampen vibrations in a component when the insert is carried by the component and when the component is vibrated. ### Claim 2 (depends on 1) A product as set forth in claim 1 wherein the filler is composed of a first material, and the body is composed of a second material, the first material having a lower melting temperature than the second material. ### Claim 3 (depends on 1) A product as set forth in claim 1 wherein the filler is composed of a first material and the component is composed of a third material, the first material having a lower melting temperature than the third material. ### Claim 4 (depends on 1) A product as set forth in claim 1 wherein the filler completely fills the cavity. ### Claim 5 A product comprising: a component that is manufactured by a casting process; and at least one insert carried at least partially within the component, the at least one insert having a body defining a cavity with a filler held in the cavity, wherein the at least one insert helps dampen vibrations in the component when the component is vibrated. ### Claim 6 (depends on 5) A product as set forth in claim 5 wherein the at least one insert is bounded on all sides by the component. ### Claim 7 (depends on 6) A product as set forth in claim 6 wherein the body has a generally oval shape in cross-sectional profile, and the body extends from a first end that is closed to a second end that is closed, the body having a generally open ring shape, and the cavity being completely bounded by the body between the first end and the second end. ### Claim 8 (depends on 5) A product as set forth in claim 5 wherein the at least one insert is welded at least partially within the component. ### Claim 9 (depends on 5) A product as set forth in claim 5 wherein the filler is composed of a first material, and the body is composed of a second material, the first material having a lower melting temperature than the second material. ### Claim 10 (depends on 5) A product as set forth in claim 5 wherein the filler is composed of a first material and the component is composed of a third material, the first material having a lower melting temperature than the third material. ### Claim 11 (depends on 5) A product as set forth in claim 5 wherein the filler completely fills the cavity. ### Claim 12 (depends on 5) A product as set forth in claim 5 wherein the component is a brake rotor comprising a cheek portion and a hub portion extending from the cheek portion, the at least one insert being a single insert that is carried at least partially within the cheek portion. ### Claim 13 (depends on 5) A product as set forth in claim 5 wherein the at least one insert comprises a plurality of inserts spaced apart and carried at least partially within the component. ### Claim 14 A method of making a product, the method comprising: providing a body that is hollow between a first end and a second end; at least partially filling the body with a filler; closing the first end and the second end to define a cavity and to trap the filler within the body; and inserting the body at least partially within a component. ### Claim 15 (depends on 14) A method as set forth in claim 14 further comprising: bending the body to form a generally open ring shape; and flattening the body to form, in cross-sectional profile, a generally oval shape. ### Claim 16 (depends on 14) A method as set forth in claim 14 wherein the inserting further comprises casting the component over the body so that the body is bounded on all sides by the component. ### Claim 17 (depends on 14) A method as set forth in claim 14 wherein the inserting further comprises welding the body within the automotive component. ### Claim 18 (depends on 14) A method as set forth in claim 14 further comprising providing the filler being composed of a first material, and providing the body being composed of a second material, the first material having a lower melting temperature than the second material. ### Claim 19 (depends on 14) A method as set forth in claim 14 further comprising providing the filler being composed of a first material, and providing the component being composed of a third material, the first material having a lower melting temperature than the third material. ### Claim 20 (depends on 14) A method as set forth in claim 14 wherein the filling further comprises filling the body completely with the filler. ### Claim 21 A product comprising: a brake rotor comprising: a cheek portion; a hub portion extending from the cheek portion; and an insert being cast over by the cheek portion to be bounded on all sides by the cheek portion, the insert having a body extending from a first end that is closed to a second end that is closed, the body defining a cavity between the first end and the second end, a filler being held within the cavity to help dampen vibrations in the brake rotor, the filler being composed of a first material and the body being composed of a second material, the first material having a lower melting temperature than that of the second material. ### Claim 22 A method comprising: providing a self-contained dampening device in a body portion of a component; and inserting the self-contained dampening device in the body portion to dampen the component. ### Claim 23 (depends on 22) A method as set forth in claim 22 wherein the self-contained dampening device is free to move in the body portion so that movement in the body portion also dampens the component. ### Claim 24 (depends on 22) A method as set forth in claim 22 wherein the self-contained dampening device is bonded to the body portion.
