If your suitcase wheels are busted, this PATIKIL replacement set can save you from buying a whole new luggage. The wheels are 1.89 inches in diameter with a hole distance of 1.3x1.5x1.3x1.5 inches - just make sure to measure your old wheels first since fit varies by luggage brand. The plastic and metal construction feels durable with good bearings for smooth rolling. Installation is pretty straightforward - remove the old broken wheels with a screwdriver and attach these using the included screws. I fixed my Samsonite in about 15 minutes and it rolls like new again. The wheels handle weight well and swivel smoothly, much better than the cheap replacements you find at some stores. Comes with 8 fixing screws and even a screwdriver, so you've got everything needed for the repair. Way more cost-effective than replacing your entire suitcase or paying for professional repair. Just double-check your measurements before ordering since there can be slight variations between luggage models. If your wheels are worn out or broken, this simple fix can extend your luggage's life for years.
