Regular maintenance will help extend the life of the Portal Axle Gear 11T & 21T (Part No. 21040) on the YIKONG YK4106/Pro RC Car. After each off-road drive, clean away dirt, sand, and debris from the portal axle and gear teeth to prevent excessive wear.

Apply a small amount of grease to the gear teeth regularly to reduce friction and improve drivetrain efficiency. It's also a good idea to inspect the gears for excessive wear, damaged teeth, or improper gear mesh, and replace any worn parts if necessary.
Avoid frequent hard acceleration or prolonged heavy-load crawling, as these conditions place extra stress on the gears. Regular cleaning and lubrication will help keep the YIKONG YK4106/Pro RC Car drivetrain running smoothly and extend the service life of the Portal Axle Gear 11T & 21T.
