What are the symptoms of an aged swing arm rubber sleeve?
You can feel a loose chassis suspension or sometimes hear abnormal sound on the road. The high-speed stability and the maneuverability of the vehicle are not as good as before. You may find it difficult to maintain straight lines while driving.
As one of the swing arms on a car, the lower swing arm mainly supports the vehicle body and the shock absorber while cushioning vibrations on the road. It works in conjunction with the shock absorber and the spring to form a complete suspension system. The lower swing arm helps support the vehicle weight, and meanwhile plays a part in the steering system. The rubber sleeve on the lower swing arm serves an immobilization purpose, and is connected to the shock absorber.
In normal drives, the whole chassis suspension (including the lower swing arm) is always subject to alternating stress. Most connection parts use rubber for absorbing vibrations. The rubber material may age or break over time. Since the majority of cars in China are based on a front-engine front-drive layout, their front suspension parts are subject to heavier loads. Hence the front suspension typically experiences a failure earlier than the rear suspension.
