YIKONG YK4084/Pro Parts Body Lock Set 14306
The quick-release body shell of the YIKONG YK4084 RC Car is held by latch 14306 at the center of the front bumper. Dirt ingress or plastic aging can stop the button from springing back, and the shell won't seat tightly.
1. Original Configuration
14306 is the body lock set. Page 2 of the manual describes the operation: press both sides of the latch buttons with one hand while lifting the shell with the other; when reinstalling, press until you hear a "click."
2. Why It Jams
Crawling environments are full of dirt; once fine sand gets into the latch gaps, button travel shortens and it won't press down far enough to release. In winter, plastic becomes brittle and the catch tabs can break. Symptoms: the shell wobbles by hand after installation, or the button won't spring back after pressing.
3. Fix
Don't disassemble yet—spray WD-40 Precision Electronics Cleaner (avoiding electronics) into the latch gaps and press repeatedly to flush out the dirt. If the button still jams, remove the latch and clean it. If the catch tab is broken, you'll have to replace the 14306 parts.
4. FAQ
Does a loose body latch affect driving?
Yes. A wobbling shell rubs against the wiring, and in severe cases the shell corners knock against the chassis—both noise and wear follow. Fix it if it won't hold; don't live with it.
Is the latch sold separately?
Yes, 14306 is the body lock set—buy by part number.

5. Conclusion
The 14306 parts aren't expensive, but don't yank the shell when installing or removing it on the YIKONG YK4084 RC Car. Press the button fully before lifting, and you'll replace it far less often.
