Truck Air Spring Maintenance Guide (Daily & Periodic)

Maintenance Type	Inspection/Maintenance Item	Specific Operations and Standards	Precautions
I. Daily & Weekly Checks	1. Visual Inspection	Air Spring Body: Check the surface for cracks, cuts, bulges, abnormal wear, or oil stains. Peripheral Clearance: Ensure there is no contact or friction between the air spring and components like the frame or leaf springs. Mounting Points: Check if the upper and lower base mounting bolts are tight.	Fine cracks indicate aging, while cuts and bulges require immediate attention.
I. Daily & Weekly Checks	2. Operational Status Check	Listen for Leaks: Listen for obvious hissing sounds when the vehicle starts and the air system pressurizes. Observe Vehicle Height: Check if the vehicle is level on both sides when unloaded and loaded. Soap Water Leak Test: Spray soapy water on suspected areas (air spring, connections) and observe for bubbles.	One side sitting low typically indicates a fault with that air spring or leveling valve. The soapy water test is the most effective method for locating leaks.
II. Periodic Maintenance & In-Depth Checks	1. Cleaning Maintenance	Clean the air spring surface with water and neutral soap to remove dirt, mud, and salt. Allow it to air dry naturally after cleaning.	Strictly avoid using strong chemical solvents like gasoline or thinners. Avoid direct close-range spraying with high-pressure washers.
II. Periodic Maintenance & In-Depth Checks	2. Related System Checks	Air Dryer: Replace the filter cartridge regularly to ensure a dry and clean air supply. Lines & Connections: Check all air lines for aging, cracking, wear, and ensure connections are secure. Leveling Valve: Check if the linkage operates smoothly without sticking; manually actuate it to listen for inflating/deflating sounds to assess its operation.	Moist, oily air severely damages the entire air system. A stuck leveling valve causes incorrect ride height and air spring damage.
