How to Lubricate the Shock Absorber Pressure Bearing?
2 Answers
Locate the shock absorber and inject grease into the central pressure bearing. Below are specific details about the shock absorber pressure bearing: 1. Composition of the automotive shock absorber thrust bearing The thrust bearing is also known as the pressure bearing. 2. The automotive shock absorber pressure bearing consists of a row of steel balls (with a cage), a shaft washer (tightly fitted to the shaft), and a housing washer (with a gap to the shaft but tightly fitted to the bearing housing bore). 3. The automotive shock absorber pressure bearing serves as a flexible link between the shock absorber and the vehicle body, preventing direct friction. 4. The shock absorber pressure bearing uses high-precision cylindrical rollers (needles) to increase contact length, enabling the bearing to achieve high load capacity and stiffness in a very compact space.
I've been repairing cars for years, and there's a proper method for lubricating the shock absorber's pressure bearing. First, ensure the vehicle is safely lifted and the wheels are removed, then check if the bearing has a grease fitting or if the seal is intact. If there's a grease fitting, use lithium-based high-temperature grease and a professional grease gun to inject gently—don't overfill to avoid leaks or seal damage. After greasing, wipe off any excess grease and test if the shock absorber rotates smoothly. Regular checks every 10,000 kilometers can prevent rust or unusual noises in the bearing. Neglecting this can lead to wear in the entire suspension system, costing more to repair later. Tools are available at auto repair shops, and beginners should work patiently to avoid damaging parts with excessive force. Safety first—remember to wear gloves and goggles before handling.
