Modern LEGO wheel hubs are identified to endure from a number of slack. Other drawbacks are that you would be able to solely use them with CV-joints – not with the stronger and extra angleable U-joints – and the part inbetween the pin holes of the hub is wider than 1 stud.
While enjoying with one among them I seen that a part of the slack is as a result of the DBG pins do not sit very tight within the wheel’s pin holes. It helps somewhat when you’ve got an axle working by the wheel which extends into the DBG-part of the hub, however not a lot. So I regarded into utilizing a turntable as wheel hub for the 15038 wheel (with 6 pinholes) with out modifying it and it offers fairly a very good outcome. Better than the LEGO wheel hub:
The flip desk is connected to the wheel with 2 3L pins. The meeting contained in the wheel makes certain the flip desk’s pinholes are connected to a pin and to not an axle (which might give slack) and sits tight in opposition to the within of the wheel to present stability. Finally an additional belt wheel is connected to the wheel to present much more stability to the two 3L pins that join the meeting to the wheel.
You can do kind of the identical for the 56908 wheels. With crossblocks. The solely downside in comparison with the larger model is that there are two 3L axle working by the turn-table pin-holes, which introduces somewhat slack, however nonetheless a lot lower than the LEGO wheel hubs:
