An anti-rattle sleeve (10) that includes a retention feature (24) on a split end (22) that extends radially from the body portion (18) and a slot (26) configured to allow the retention feature (24) to be pressed through an opening (20). The sleeve (10) also includes a flange portion (30) opposite the split end (22) that includes an inner bump (36) configured to contact a surface of an object bracket (12) and an outer bump (40) configured to contact a surface of a mounting bracket (14). The inner bump (36) and the outer bump (40) are located relative to the slot (26) such that the sleeve (10) is deformed by the brackets in a manner effective to reduce relative motion between the object bracket (12) and the mounting bracket (14) when compressed between the brackets.
