FAQ

Q1: Why are there different front and rear Hex Wheel Hubs?

The front and rear axle designs of the YIKONG YK41011 RC Car are different, so this set includes Short front hubs and Long rear hubs. Always install them in their correct positions.

Q2: What happens if the Hex Wheel Hubs become worn?

Worn Hex Wheel Hubs can cause wheel wobble, reduced drivetrain efficiency, and eventually rounded hex holes that allow the wheels to slip under power.

Q3: Do the Hex Wheel Hubs require lubrication?

Generally, no lubrication is required. Simply keep the mounting surfaces clean. If the axle shows light corrosion, a small amount of anti-rust lubricant may be applied, but avoid getting grease on the wheel mounting surfaces.

Q4: How often should I inspect the Hex Wheel Hubs?

For normal driving, inspect them every 20–30 runs. If you frequently drive off-road, through water, or at high speed, inspect them more often.
