Frequently Asked Questions

Q1: There is a "squeaking" noise from the coupler during towing after installation. What is the reason?

Solution: Check anti-slip gaskets for aging, adjust engagement gap to 0.1-0.2mm, and clean engagement surfaces.

Q2: After long-term use in coastal areas, the black coating peels off locally. How to handle it?

Solution: Polish affected area, apply black epoxy touch-up paint, and enhance with protective wax.

Q3: How to confirm if my trailer is compatible with YD36-008?

Check: Ball diameter (must be 2"), trailer weight (≤5,000 LBS), and installation conditions.

Q4: What problems will occur if the torque value is too high or too low when installing bolts?

Proper Installation: Use torque wrench (40-45N*m for M10 bolts), tighten in diagonal sequence, and conduct post-installation test.
