What are some common problems and maintenance recommendations for drive shaft rubber bushings?

Common Problems and Maintenance Recommendations
Aging and Cracking
Cause: Long-term exposure to UV rays, high temperatures, or chemicals causes the rubber to harden and crack.
Identification Method: Inspect the rubber bushing surface for cracks, deformation, or signs of oil leakage.
Replacement Interval: Recommended inspection every 20,000 kilometers, with mandatory replacement between 60,000 and 80,000 kilometers (adjusted based on operating environment).
Abnormal Noise Diagnosis
Symptom: A "clicking" sound during acceleration or bumpy driving may indicate damage to the rubber bushing, causing the drive shaft to shift.
Remedy: Replace the rubber bushing immediately to avoid a safety incident caused by a broken drive shaft.
Selection Considerations
Material Matching: Select the rubber type based on the climate (e.g., cold-resistant silicone in northern China, heat-resistant EPDM in southern China).
Dimensional Accuracy: The inner diameter of the rubber bushing must strictly match the outer diameter of the drive shaft, otherwise it may loosen or fall off.
