I’d start by checking the make and model on the bin itself. Look for a sticker, molded logo, or serial number near the lid, wheels, or base. Once you have that information, search for the manufacturer’s replacement parts page or contact their customer service. If the bin was issued by your city or a waste-management contractor, call them too—they often keep spare wheels, lids, pins, and hinges or can tell you which model you have.
Next, get the exact part number if possible. Take clear photos of the damaged part and measure it, especially for wheels, axles, lid hinges, and pins. This helps avoid buying something that looks similar but won’t fit. I’d also ask the manufacturer or city whether the bin is under warranty, because replacement parts may be free or discounted.
If the official route is slow, check local waste-equipment dealers, repair shops, and reputable online marketplaces using the brand and part number. Universal wheels and pins can work, but check the diameter, axle length, and load rating first. Avoid drilling or forcing mismatched parts, since that can weaken the bin or make it unsafe to handle. When in doubt, send photos and measurements to a supplier before ordering.
