If the front wheels don’t spin as well as they used to, or if they become easily stuck, the issue is likely with the wheel ball bearings.

Yoyo sells spare wheel kits for 45 €. However, you may not need four new wheels. In the end, it’s as easy to just change the wheel bearings as replacing the entire wheel.

Some people mention needing a grinder, a saw, pliers… No, you just need a hammer and two screwdrivers.

  • Unscrew both sides of the wheel with two T30 screwdrivers.
  • One screw will likely become loose. The hollow one (the axle) will likely be stuck (as people complained). The axle got solidary with the bearings.
  • Screw back the male side back again, and with a hammer, hit on it. !yoyo-1.jpg This should push the axle out. It may break the bearing entirely but you were planning to remove it anyway.
  • There are two bearings per wheel. Remove the existing damaged bearings.
  • Replace the bearing with the proper replacement. !yoyo-2.jpg The bearing reference is 6900ZZ, and you can find it, for instance on Amazon.
