The arm is a \u003cstrong\u003ezinc-colored metal bracket\u003c\/strong\u003e formed with a \u003cstrong\u003eright-angle bend\u003c\/strong\u003e, and the grommet sits in the arm ready to receive the \u003cstrong\u003emotor mount\u003c\/strong\u003e, so the whole thing goes in as one \u003cstrong\u003eCarrier factory assembly\u003c\/strong\u003e.

The \u003cstrong\u003earm\u003c\/strong\u003e provides that \u003cstrong\u003erigid support\u003c\/strong\u003e, and the \u003cstrong\u003egrommet\u003c\/strong\u003e is the \u003cstrong\u003eisolator\u003c\/strong\u003e between the motor and the metal, which keeps \u003cstrong\u003evibration\u003c\/strong\u003e and \u003cstrong\u003enoise\u003c\/strong\u003e out of the \u003cstrong\u003ecabinet\u003c\/strong\u003e. When the \u003cstrong\u003erubber hardens, cracks, flattens or gets soaked in oil\u003c\/strong\u003e, the motor drops slightly and starts to \u003cstrong\u003ebuzz, tick or rattle\u003c\/strong\u003e, and a \u003cstrong\u003ebent arm\u003c\/strong\u003e lets the shaft drift, which wears the \u003cstrong\u003emotor bearings\u003c\/strong\u003e and can make the \u003cstrong\u003ewheel rub\u003c\/strong\u003e.
