1/10 Scale SCX10 III Jeep Rubicon JL | Clicking noise troubleshooting

Thanks for watching my videos. Please like and Share for more fun rc videos. First, please understand my lack of English skills. I think the assembly manual is very stale as I noticed in the build video. That’s why many SCX100 IIIs generate clicking noise. I tried to figure out the cause. # Jeep Rubicon JL - Kit : SCX10 III Jeep JLU Wrangler w/Portals 1/10th KIT
