ROOF RACK HOWL/WIND NOISE
MODELS:
ALL S/T UTILITY VEHICLES (JIMMY) WITH (RPO V54 OR V55) ROOF RACK
Some S/T Utility Vehicles (Jimmy) with options (RPO V54 or V55) roof racks may experience a roof rack howl. This howl has been determined to be
caused by the height difference between the roof rack cross rails and the rubber strip within the rail. This condition results in a howl/wind noise as air
flows across the rail, much like a reed in a wind instrument.
