Tired of that annoying wobbly wheel on your favorite suitcase? This 4-pack replacement wheel set is exactly what you need to get your luggage rolling smoothly again! Each wheel measures 45mm in diameter and 18mm thick, made from durable rubber that's quiet and wear-resistant. The double carbon steel bearings ensure smooth swiveling even under heavy loads. The kit comes with everything you need for installation: 4 wheels, 4 shorter axles (30mm), 4 longer axles (36mm), 8 screws, 8 washers, and even two handy Allen wrenches. The 6mm bearing hole fits most standard luggage setups. Installation is pretty straightforward - just cut off the old wheel poles with a hacksaw and attach the new ones with the included hardware. These work great for suitcases, rolling luggage, and even some roller skates. Before ordering, definitely measure your existing wheels and axle length to ensure proper fit. Much cheaper than buying a new suitcase and way more satisfying than struggling with broken wheels at the airport! Perfect for DIY repairs that'll extend your luggage's life for years to come.
