Vertex 10 rear axle disassembly and inspection. Diagnosing why it clicks.

My vertex 10 came with a bad shutter in the rear end. Redcats great customer service took care of me by sending me a new ring and pinion gear. In this video I disassemble the rear axle to find any obvious problems. that being said. I already had it apart and checked the lash previously. The rear end lash is and was good to go and not the cause of the problem.
