What does 'No Greasing, No Wheel Maintenance' mean?
3 Answers
Greasing and wheel maintenance refers to the process of applying grease to car tires for upkeep, while 'no greasing, no wheel maintenance' means not applying grease or performing maintenance on car tires. Private cars (sedans) do not require greasing during maintenance. The structure and purpose of trucks determine that their chassis and transmission components must maintain good lubrication. Once the lubricant ages, fails, or is lost, it can lead to wear between parts. Therefore, trucks generally require greasing for maintenance. Below is an introduction to car maintenance: 1. Introduction to car maintenance: Car maintenance refers to the regular inspection, cleaning, replenishment, lubrication, adjustment, or replacement of certain parts as preventive work, also known as car servicing. 2. Scope of car maintenance: Modern car maintenance mainly includes the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, etc. 3. Purpose of car maintenance: The purpose of car maintenance is to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life.
I drove heavy trucks for over a decade, and wheel hub maintenance was always my biggest concern. 'No grease, no wheel care' refers to two common but wrong maintenance habits. Some drivers skip greasing the universal joints out of laziness, ignoring the squeaky sounds until the steering ball joints wear out quickly. Even more dangerous is neglecting regular wheel end bearing maintenance – I once witnessed a colleague's wheel fly off on the highway! While newer trucks have maintenance-free hubs, older models still require periodic disassembly for servicing. Oil-starved bearings overheat, causing minor issues like uneven tire wear or severe problems like seized axles and locked wheels. Don't skimp on maintenance – roadside breakdowns cost far more than a few hundred dollars in upkeep.
Our repair shop often encounters such cases. 'Not applying grease' refers to the need for regular high-pressure grease gun lubrication at vehicle joint areas, such as the ball joints of chassis control arms. 'Not maintaining wheels' specifically indicates wheel bearing maintenance, which requires removing the hub to clean out old grease and reapply high-temperature resistant lubricant. We've seen too many vehicle owners neglect maintenance, with hub bearings worn down to metal powder yet still in operation. Last year, an engineering vehicle drove into our shop with smoke coming from its rear wheels, and upon disassembly, we found all the bearing balls shattered. It's recommended to check joint lubrication every 20,000 kilometers, and heavy-duty vehicles must perform wheel-end maintenance every 50,000 kilometers.
