2 Answers
Method for replacing the differential oil seal of Wuling Hongguang: 1. First remove the tire, take off the half-shaft large screw, and dismantle the differential protective cover; 2. Locate the inner ball wheel screw and the lower arm screw, remove the half-shaft and take off the connecting bolts; 3. Remove the sealing head, take off the oil seal, and directly replace it with a new one. The differential oil seal is also called the half-shaft oil seal, which is a component on the differential to prevent lubricant leakage. If the differential oil seal needs to be replaced, it is recommended to go to a professional auto repair shop or 4S store for replacement. The oil seal has chemical stability, thermal stability, friction reduction, and self-lubricating properties, with a cracking temperature above 400 degrees. Except for free fluorine and alkali metals, it has excellent corrosion resistance to chemicals, solvents, hydroxides, and acids.
Replacing the Wuling Hongguang differential oil seal is a skilled job that requires step-by-step procedures. First, I ensure the vehicle is on a level surface and securely supported by a hydraulic jack to prevent slipping. Removing the tire and brake drum exposes the differential area. Next, drain the old differential oil, loosen the mounting bolts with a socket wrench, and gently pry out the old seal to avoid scratching the bearing seat. After thoroughly cleaning the installation surface, apply new sealant and evenly press the new oil seal into place without tilting. Finally, refill with fresh differential oil to the standard level and start the engine to check for leaks. A commonly overlooked detail is selecting genuine oil seal materials, as Wuling vehicles are sensitive to compatibility. I recommend idling for ten minutes after completion before road testing to ensure no abnormal noises or oil seepage, otherwise rework will be time-consuming.
