Normally, if the YIKONG YK4101 is used frequently, it is necessary to check and consider replacing the grease in the differential about every 3 – 6 months.
This is because as the vehicle is used, the grease may be mixed with impurities and debris from wear and tear, which may affect the lubrication effect, resulting in increased resistance to operation and wear of the differential.
If the frequency of use is low, you can check once a year and decide whether to replace the grease depending on the actual state of the grease to ensure the smooth operation of the differential.
