One feature on THECar that you don’t find on others, is the elongated holes for the hex pin in the driveshaft axle, and the crush washer between the bearings. With this setup it’s possible to remove the slop from the wheel bearings as slop begins to appear. If you have added shims along with the crush spacer simply remove a shim. If you only have the crush spacer between the bearings, you can do this!
