A refuse vehicle includes a telescopic arm, a sensor, and a processor. The telescopic arm includes an outer boom defining a bore, an inner boom received in the bore of the outer boom, and a bearing pad received in the bore and located between an exterior surface of the inner boom and an interior surface of the outer boom. The sensor is configured to output data indicating a position of a load-bearing limb of the telescopic arm. The processor is configured to receive data output from the sensor and determine a wear-state of the bearing pad based on the position.
