Grease Your Gears

It’s a good idea to doublecheck your gearboxes to ensure there’s an even coverage of grease on the bevel gear. Full disassembly isn’t required, simply remove the diff cover, usually at the front of the gearbox or a bottom plate. Inspect the bevel by rotating the drivetrain, ensuring there’s enough grease to cover the entire surface of the gear lightly.

If you notice any dry spots, or notice no grease at all, apply a bit to the bevel as it turns. It’s best to use a decent quality RC moly grease, some lightweight synthetic grease, or some lightweight marine grease on your diff gears. This same step can be applied to RC crawlers that use portal axles. Remove the portal axle cover to inspect for proper grease before you hit the trail.
