1. Regular inspection (during each maintenance): observe whether the lifting ears are aged, cracked, deformed, etc
2. Avoid washing the chassis immediately after prolonged high-speed driving to prevent rubber parts from accelerating aging due to sudden temperature changes
3. If slight abnormal noise is found, try applying silicone grease to the contact area between the lifting ear and the metal rod to alleviate friction noise
4. When modifying the exhaust system, choose matching high-strength lifting lugs to avoid premature damage caused by increased exhaust weight
