Frequently Asked Questions
- What is a differential case and why do I need to replace mine? — The differential case is the housing component that contains the gears responsible for distributing engine power to both wheels whilst allowing them to spin at different speeds during turns. Over time, through aggressive driving and normal wear, the internal gears or the case itself can become damaged, stripped, or worn. Replacing it ensures your RC car maintains smooth acceleration, predictable handling, and efficient power delivery. A damaged differential case can cause performance issues including uneven power distribution, poor cornering characteristics, and potential damage to other drivetrain components.
- Is this part compatible with both GPX4 and EPX models? — Yes, the H22003 differential case is designed and engineered to work with both HOBAO GPX4 and EPX 1/10 scale RC car platforms. This makes it a versatile spare part if you run either of these popular HOBAO models.
- Do I need special tools to install this differential case? — Installation of this differential case requires standard RC car tools and mechanical knowledge. The process typically involves removing the transmission or gearbox, extracting the old differential case, and installing the new component with proper alignment of internal gears. If you're not experienced with RC car maintenance, consult your HOBAO manual or contact an experienced RC mechanic for installation guidance.
