Truck Cab Air Spring Installation Flowchart

Stage	Step	Key Operations/Precautions
Preparation and Safety	1. Lifting and fixing cab	[Core Safety] After using a dedicated lift to raise the cab, it must be immediately supported at the load-bearing structure with a sturdy safety bracket. It is strictly forbidden to rely solely on the lift to bear the load.
	2. Relieve system pressure	Disconnect the air line connector from the old air bag and release the internal air pressure.
	3. Disconnect	Disconnect the negative battery terminal; if necessary, tag and move any wiring or lines that are in the way.
Dismantle old parts	4. Locating and disconnecting gas lines	Locate the air spring under the rear of the cab and disconnect its air line.
	5. Remove the fixing bolts	Use appropriate tools to remove the upper and lower fixing bolts. If they are rusted, use lubricant and do not use brute force.
	6. Remove old parts and inspect	Remove the old airbag and check whether the mounting bracket and stop block are cracked or damaged.
Install new parts	7. Check new parts	Confirm that the new air spring is of the correct model and has no visible damage from transportation.
	8. Initial positioning	Place the new, uninflated airbag in the installation location. Do not inflate it before securing it.
	9. Connection and fastening	First screw in the new bolts by hand to ensure accurate alignment, and finally use a torque wrench to tighten them according to the value specified in the maintenance manual.
Recovery and testing	10. Connect the gas line and restore	Connect the air lines securely (make sure you hear a "click") and reassemble all wiring harnesses and components.
	11. Remove the bracket and connect the battery	After confirming that all work is completed, remove the safety bracket and connect the negative terminal of the battery.
	12. Startup and leak detection	Start the engine and observe the airbag inflating to the working height. Check all joints for leaks with soapy water.
	13. Functional testing	Take a short test drive to feel whether the cab stability and shock absorption effect have returned to normal.
