MN Model MN98 RC Truck Parts Small Bevel Gear

A grinding noise from the axles of your MN Model MN98 RC Truck is often caused by a worn or damaged Small Bevel Gear – a common fault with plastic gears after extended use. The teeth may have stripped or become worn, causing poor meshing with the ring gear. Upgrading to a metal gear set will eliminate this issue and provide longer-lasting durability.
