The premature failure of the universal joint connecting the drive gear box and the cooling fan caused a deterioration in serviceability and operability. Universal joint is a device that transmits engine power to a cooling fan. Internal pin breakage and shaft separation can cause secondary damage such as cooling fan malfunction and radiator damage caused by component failure. The purpose of this paper is to analyze the damage phenomenon of universal joints caused by bundles in SPVs and to improve them. In order to verify the improvement, a single part test and a system conformance test were conducted, and durability test was conducted to confirm the improvement effect on the improved prototype. Through these, the effects of increasing the durability of the improved product were estimated.
