How to Unhitch
1. Properly chock your trailer.
2. Remove the 7-pin plug.
3. Remove the breakaway cable and safety chains.
4. Extend your trailer jack to lift the weight off the spring arms. (Figure 33)
5. With the tension off the spring arms, remove the Snap L-pins and slide the spring arms off
the L-bracket. (Figure 34)
6. Remove the spring arms from the hitch head.
7. Remove the safety pin and unlock the coupler.
8. Raise the trailer coupler above the hitch ball. (Figure 35)
9. Pull your tow vehicle away slowly, lock your trailer coupler and you are done. (Figure 36)
Appendix – Using a Weight Distribution
Hitch with Auto-Leveling Suspensions
Always refer to and follow your tow vehicle owner’s manual or air bag instructions for their
requirements for use while towing. Auto Leveling will greatly affect your towing situation.
Step 1 - Ready the Tow Vehicle and Trailer
Turn off or disable air bag suspension or auto-leveling systems for the hitch setup process. Allow
the suspension to adjust to normal position before turning it off. To turn the auto level off, the
system may have an off switch, a jack mode setting, or you may need to turn off the vehicle.
Steps 6 and 7 – Set Up and Adjust Weight Distribution
4 Corner Auto-Leveling Suspension:
4-corner auto leveling systems will decrease the weight distribution amount by 20 — 25%. If it is
possible to disable the auto leveling so that it remains off while driving, do so. If not, then set up
the hitch so that 75 — 100% weight distribution is achieved. This will help compensate for the
loss from auto leveling.
Rear Auto-Leveling Suspension:
When using rear auto-leveling suspension systems follow the instructions to Step 6 - line C. Allow
the vehicle to auto level the rear before taking measurement C. On hydraulic or pneumatic
systems this is done by turning the vehicle on and letting the engine idle while it levels. If your
vehicle is equipped with a system that requires the tow vehicle to be driven, mark where it is
parked so that you can return to the same spot after driving to take measurement C.
