8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Hitch mount does not fit into receiver. | Incorrect receiver size (not 2" x 2"). Obstruction in receiver. | Verify receiver size. Clear any debris from the receiver. |
| Hitch pin cannot be inserted. | Holes not aligned. Debris in pin holes. | Adjust ball mount position until holes align. Clear pin holes. |
| Excessive rattling or movement. | Loose fit in receiver. | Ensure pin and clip are fully engaged. Consider an anti-rattle device (sold separately) if movement persists. |
| Trailer not level. | Incorrect drop/rise for vehicle/trailer combination. | The CURT 45134 has a fixed 2-inch drop. If a different drop/rise is needed, a different ball mount may be required. |
