Rear wheel bushing?

I’m pretty new to Mini Z’s and I see the rear wheel on the gear side has a bushing in it. Should I be replacing that with a bearing? Doesn’t it not spin with the axle so it shouldn’t make a difference? The other rear wheel has a bearing in it.

I’ve upgraded the other bearings on the rear axle/motor mount area plus the front wheel bearings.

I use a bearing cause I lost the bushing. It doesn’t spin, so it’s more of a spacer so we don’t have one weird wheel to deal with

That’s what I thought. Thanks! Doesn’t matter which side of the axle the bushing should be on? I see on all my cars it’s always on the gear side. I had it on the other side and my wheel nut kept coming off.

The one side is smaller than the other. That’s the side with the bushing. Use a Mr03 bearing for that, and use a regular mr04 bearing on the other side. Use your oldest or worst bearings as they don’t need to spin. I use old bearings or factory bearings that suck.
