Can you Use a Plastic Bushing or Steel Ball Bearing as an Axle Spacer or Shim?

The Tamiya GH2 (Grasshopper II) comes with really wide pin drive to 4 point wheel adapter mounts on the rear axle, but if you upgrade your wheels to the Hornet Large Diameter Wheels you need to use the very narrow 5 point adapter wheel mounts, which leaves a lot of threaded axle and a smidgen of unthreaded axle, meaning your nylock nut will get stuck if you tighten it up enough to prevent wheel wobble. We look into 3 ways how to fix this problem in this episode of the RC Deep Dive podcast.
