BD9 double joint maintenance

This maintenance kit contains one set of replacement components intended for the BD9 series double joint universal on 1/10 scale RC touring car drivetrains.

Installation is intended for hobbyists familiar with basic drivetrain disassembly, the kit fits into the existing universal assembly and replaces the joint components directly, it does not require additional tools beyond common hobby hand tools and a hex driver for hub removal.

On setup and tuning the kit helps maintain consistent wheel coupling and reduces slop that can affect cornering predictability, use it as part of periodic inspection and after intensive running sessions to keep the drivetrain operating as intended.

This kit is a direct replacement service set for BD9/BD10 family double joint universals, intended to be used during scheduled maintenance to preserve drivetrain consistency and handling balance.
