Truck grease application is typically done at the leaf spring shackles, grease nipples, drive shaft, steering linkage, and kingpin. Depending on different load capacities, grease is generally applied to high-friction areas under heavy loads. Grease serves as a lubricant, and as trucks operate over time, the internal grease wears out, requiring fresh replenishment for continued vehicle . Difference between grease and lubricating oil: Non-volatile oily lubricants are referred to as lubricating oils, which can be categorized into three main types: animal/vegetable oils, petroleum-based lubricating oils, and synthetic lubricating oils, widely used in automotive and industrial machinery. Grease is essentially a lubricating grease, belonging to the petroleum-based lubricating oil category, primarily used for mechanical components that require a semi-solid, paste-like lubricant, such as rails, rotating shafts, bearings, and gears. Lubricating oils used in various types of vehicles and mechanical equipment to reduce friction protect machinery and processed parts with liquid or semi-solid lubricants, serving key functions such as lubrication, cooling, rust prevention, cleaning, sealing, and cushioning. Grease is also a type of lubricating oil, but in a semi-solid state, whereas engine oil is in a liquid state. The choice between grease and liquid lubricants depends on the machinery's requirements, with grease used in certain parts and liquid lubricants required for others.

I've been driving trucks for over a decade, and the main greasing points are at the suspension joints – like the ball joint bushings on the front axle, the universal joints on the rear axle, and the connecting points of the steering arms. If these areas lack lubrication, the truck starts squeaking when moving, and you'll feel jerking or even part wear during turns. Every time I visit the service station, I ask the mechanics to pay special attention to these spots. Regularly adding grease every 3,000 to 5,000 kilometers can extend component lifespan several times over. Once, I neglected rear axle lubrication, and the seized universal joint cost me over 10,000 yuan for replacement parts – still hurts to think about. That’s why I’ve made it a habit to check the lubrication point list in the manual rather than relying solely on mechanics' reminders. Safety always comes first.

I often work on these types of vehicles, and there are quite a few critical points for greasing a truck. The ball joints in the suspension, universal joints, hinge connections under the chassis, as well as the hook and shackle sections all have grease fittings. Applying grease helps reduce friction, prevent rust, and avoid premature wear, especially when carrying heavy loads, which accelerates wear. I recommend checking every 5,000 kilometers or based on road conditions, using a grease gun to apply high-quality lubricant. Neglecting this can easily lead to increased fuel consumption and steering failure. I've seen many trucks end up in the shop for major repairs due to this, costing both time and money. With simple maintenance, the vehicle can easily last over ten years without issues.

When I first bought the truck, I wasn't sure where to apply grease. Later, I learned it's mainly at the suspension joints, like the bearing points connecting the wheels. Lubricating these areas made driving much smoother, reduced noise, and gave the vehicle a lighter feel. Now I do it myself, remembering to do it regularly. It's simple, easy to learn, saves money, and helps prevent major component issues.

In our fleet operations, the greasing points for trucks mainly involve key joints under the chassis, such as suspension ball joints and universal joints. Neglecting increases repair frequency and fuel consumption. We train drivers to inspect these areas and lubricate them according to mileage to ensure efficient vehicle operation. Regular greasing reduces part replacement costs, enhances overall fleet reliability, and minimizes unexpected breakdowns that could impact transportation efficiency—an effective approach.

I usually use a truck for work in the countryside, and the key points for greasing are the suspension joints, especially the universal joints and steering connections. The bumpy dirt roads cause a lot of friction, and without proper lubrication, the noise increases and parts wear out easily. I make it a habit to check once a week, keeping a grease gun handy for a quick spray. This keeps the vehicle running smoothly, extends its lifespan, and saves money—a good habit to have.
