Cab air springs support the cab on heavy-duty trucks and reduce vibration. When replacing a cab air spring, verify the part number, ride height, mounting style, and air-line fitting. Common symptoms of failure include cab leaning, excessive vibration, air leaks, and fault codes related to ride height. Always use manufacturer torque specifications and inspect the leveling valve and height sensors.
