What does it mean when the LaCrosse displays 'Check Suspension System'?
1 Answers
When the Buick LaCrosse displays 'Service Suspension System', it indicates a malfunction in the suspension system that requires prompt inspection and repair. Concept of the Suspension System: The high-end models of the new LaCrosse feature an electronic suspension system, significantly enhancing ride comfort. The electronic suspension control system independently adjusts the damping force of each of the four shock absorbers to optimize vehicle ride smoothness. The suspension system refers to all the force-transmitting connection devices between the vehicle's frame and the axles or wheels. Its functions include transmitting forces and moments between the wheels and the frame, cushioning impacts from uneven road surfaces to the frame or body, and dampening resulting vibrations to ensure smooth vehicle operation. Common Suspension System Faults: Wear or loosening of ball joints can be checked by lifting the vehicle and gently shaking the tires to assess play, or by using a pry bar to inspect ball joint gaps and looseness. Solutions include tightening bolts and replacing connecting rods or ball joints. Aging or damage to control arm rubber bushings can be inspected by prying with a bar to check for cracks or deterioration. Solutions involve replacing the bushings or the entire control arm assembly.
