Which models will accept this front shaft without modification?

The S4-01077A is intended for YZ-4S layouts and is compatible with other Yokomo models that share the same front shaft dimensions, including B-YZ4SF, B-YZ4SF2-1, MOR-010 and MOR-020.

What lubricant should I use on the dogbone ends?

A light synthetic or silicon-based grease is suitable for the dogbone cups to reduce friction without attracting excessive dirt; avoid heavy grease that can fling off.

How can I check for wear in the universal shaft quickly?

Rotate and wiggle the shaft in the cups; play, visible scoring or metal burrs indicate it is time to refurbish or replace the dogbones.

Any tips for reducing drivetrain noise after fitment?

Ensure correct seating, check for bent pins or worn cups, and apply a small amount of clean grease; balanced driveshafts and correct alignment lower noise.
