3. Secure with Nuts: Hand-tighten the provided hex nuts onto the bolts to hold the hitch in place.
4. Tighten and Torque: Evenly tighten all fasteners with a hand wrench. Once snug, use a torque wrench to tighten all bolts to the specific torque values indicated in the installation instructions provided with your hitch. Do not use excessive torque or an impact wrench.

• โซ่ความปลอดภัย: Always attach safety chains from the trailer to the designated chain loops on the hitch. Cross the chains under the trailer coupler to prevent the coupler from hitting the ground if it detaches.
• การเชื่อมต่อไฟฟ้า: Connect the trailer's electrical plug to your vehicle's wiring harness to ensure proper functioning of trailer lights and brakes.
• การกระจายน้ำหนัก: For heavier loads, consider using a weight distribution system to distribute the trailer's tongue weight more evenly across the vehicle's axles.

7 การแก้ไขปัญหา

ปัญหาทั่วไปและแนวทางแก้ไขที่เป็นไปได้:

• Difficulty Installing Bolts: Ensure frame threads are clean. Use a wire brush and lubricant. Pre-tapping with an M12-1.75 tap can help. If bolts are self-tapping, ensure they are started correctly.
• Hitch Not Aligning: Ensure all obstructions are removed. Verify the hitch model is correct for your specific vehicle year, make, and model. Slight adjustments may be needed during initial hand-tightening.
• U-Bolt Torque Issues: Always follow the manufacturer's specified torque values. Over-tightening can damage bolts. If U-bolts are used, ensure they are tightened evenly and in stagใช่
• Excessive Play in Receiver: Ensure the ball mount is fully inserted and secured with a hitch pin and clip. Consider an anti-rattle device if excessive movement persists.
