Poolvergnuegen Wheel Sub Assy, The Pool Cleaner™ 2-wheel / 4-wheel

OEM Hayward parts. The wheel sub assembly consists of two parts, the wheel on which the tire mounts and the bushing. I have owned the 2 wheel version of The PoolCleaner for about ten years. Over that period, I have had to replace the wheel sub assembly 3 times. The wheel is always fine but the bushing is the part that wears out. Unfortunately the bushing is not sold separately and the only option is to purchase the sub assemble. I am sure Hayward is aware of this and it sad they don't sell the bushing separate which would be considerably less expensive.
