💡 What causes premature wear on heavy duty weld on hinges?
Premature failure usually stems from moisture trapping and misalignment. Follow these steps to maximize service life:
- Seal the weld zone completely to stop road salt from eating the pin
- Pump lithium grease through the zerk nipple every few months
- Measure twice before torching to keep the pivot square under weight
- Swap out worn barrels immediately so the frame takes zero stress
