Proper lubrication is essential for maintaining the performance and longevity of your passenger car. While lubricating oil is commonly used for the engine and transmission, grease plays a crucial role in protecting moving parts that experience friction. Additionally, using the right cleaning agent ensures contaminants don’t degrade lubrication effectiveness. Let’s explore which parts of your car need greasing.
　　1. Wheel Bearings
　　Wheel bearings endure heavy loads and rotational stress. Applying high-temperature grease prevents overheating and premature wear. If bearings become noisy or loose, they may require cleaning with a cleaning agent before regreasing.
　　2. Suspension Components
　　Ball joints, tie rod ends, and control arm bushings rely on grease to minimize friction. Over time, dirt buildup can reduce lubrication effectiveness—regular cleaning and regreasing extend their lifespan.
　　3. Steering System
　　Steering linkages and universal joints benefit from periodic greasing. Ensure old grease is removed using a cleaning agent before applying fresh lubrication for smooth steering response.
　　4. Door Hinges and Latches
　　Though often overlooked, door hinges and locks require lithium-based grease to prevent squeaking and corrosion. Wipe away debris with a cleaning agent before greasing.
　　5. Driveshaft and U-Joints
　　The driveshaft's universal joints (U-joints) must be packed with grease to maintain flexibility. Neglecting this can lead to vibrations and drivetrain failure.
　　6. Brake Components
　　Brake caliper pins and sliding surfaces need high-temperature grease to ensure proper movement. Avoid mixing grease with brake fluid—clean thoroughly with a cleaning agent if contaminated.
　　7. Battery Terminals
　　While not greased traditionally, applying dielectric grease on terminals prevents corrosion. Clean terminals first with a specialized cleaning agent.
　　Conclusion
　　Regular greasing enhances your car’s performance and prevents costly repairs. Always pair lubrication with proper cleaning using a suitable cleaning agent. Whether it’s lubricating oil for internal components or grease for joints and bearings, proper maintenance ensures a smooth ride.
　　Remember: Check your owner’s manual for manufacturer-recommended greasing intervals.
