A suspension system is the backbone of BMW’s better ride quality and handling. BMW vehicles are known for their precision engineering, which delivers a smooth driving experience. For this reason, the suspension system needs to operate flawlessly.
It is essential to understand common BMW suspension issues, how to diagnose and fix them, and how local driving conditions can place additional load on your BMW’s suspension.
Importance of a BMW’s Suspension
A BMW’s suspension system is designed to absorb road imperfections and maintain proper tire contact while delivering improved handling. From the advanced multi-link rear setup to the electronically controlled dampers, all components play a crucial role. If any of these systems fail, it can compromise comfort and safety and reduce vehicle longevity.
John’s Creek experiences variable weather, including occasional heavy rains and temperature fluctuations, which can cause potholes and patching that significantly affect suspension performance. Other factors include frequent stop-and-go traffic in suburban areas, which can lead to wear and tear. So, the John’s Creek drivers need to become proactive.
Common BMW Suspension Issues
- Worn Struts and Shocks – Struts and shocks are crucial for damping movement and stabilizing the BMW. If they wear down, you may hear knocking or notice longer stopping distances. Common symptoms include bouncier rides, nose-diving during braking, and loss of control during cornering.
- Damaged Control Arm Bushings – The control arm bushings are a critical component of your suspension, reducing metal-on-metal contact and delivering a smooth driving experience. Deteriorated bushings can cause unwanted movement and noise. Symptoms include a clunking noise over bumps and a loose steering response.
- Faulty Ball Joints – Ball joints connect the control arms to the steering knuckles, enabling smooth wheel movement. If it fails, then it could be a safety hazard. Specific symptoms include uneven tire wear, loose steering, and metallic clunking sounds.
- Broken Springs – Springs support the vehicle’s weight and absorb shock. In BMW vehicles, a broken spring can affect alignment and comfort. Specific symptoms include uneven ride height, vehicle leaning to one side, and increased road noise.
- Leaking Shock Absorbers – Leaking shocks not only reduce damping efficiency but can also accelerate tire and suspension wear.
Causes of BMW Suspension Problems
- Wear and Tear – BMW Suspensions can degrade over thousands of miles. Over time, the bushings can develop cracks, leading to fluid leaks.
- Environmental Factors – Certain conditions, such as wet seasons, can cause potholes or a rough surface, which require the suspension to work harder.
- Driving Habits – Certain driving habits, such as aggressive driving, frequent stops, and carrying heavy loads, can shorten the lifespan of the critical components.
- Road Salt and Humidity – Frequent road repairs in Georgia‘s summer humidity and winter weather can lead to corrosion of metal suspension components.
How to Diagnose BMW Suspension Issues
- Visual Inspections – Check for cracks, tears, or leaking rubber bushings. Look for signs such as oil leakage on shocks and struts, and inspect the springs for signs of breakage or rust.
- Bounce Test – Perform the test by pressing on each corner of the vehicle and releasing. If the car continues to bounce more than once or twice, the shocks or struts may be worn.
- Listen for Unusual Sounds – To check whether unusual sounds are present, drive over speed bumps or rough roads at low speeds and note any clunking, squealing, or knocking.
