A Mercedes comes with the whole package: A stylish exterior, a dashing interior, top of the line accessories, impressive performance, and is sure to turn heads wherever you go. Occasionally, a component can go bad, ruining some of the great benefits that come with owning a Benz.
One common issue that Mercedes suffer from is thrust link bushing failure. Now, if you know about cars, you understand that this component can have serious, negative impacts on your car’s suspension if faulty. And for whatever reason it went bad, it needs to be repaired. If you don’t know about this part, this article serves as an explanation.
To help you understand why your Mercedes thrust link bushing has failed, we’re here to explain what the thrust link bushing is, the purpose it serves, why it goes bad, and what you can do when it does. Let’s begin.
What’s a thrust link bushing?
Thrust link bushings are only a component of a larger piece of your suspension system. A thrust link, also known as a control arm/thrust arm, helps stabilize each wheel as you drive. Without the thrust link, your wheel would be extremely mobile and unable to support your car during turns and braking. It also helps to provide resistance needed to keep your Mercedes aligned and up right.
The thrust link bushings are what absorb the weight and force soaked up by the thrust link. You can think of the bushings as your joints. Like the cartilage around the ends of bones that make up a bone joint, bushings soften the friction between two major points of force in your suspension system. As you can see, this component is essential for your Mercedes to operate at its usual high level performance when making turns or cutting corners.
Why does a thrust link bushing go bad?
Your bushings can go bad over time as the fluid inside dries out or leaks from a crack. This can happen at any time during your Mercedes lifespan but will certainly happen sooner if you drive at the car’s peak performance.
When the bushings wear out, you’ll be able to hear, feel, or see that your suspension is damaged. Sometimes you may hear a popping or creaking noise when turning because the thrust arm is making direct metal-to-metal contact with the suspension cradle.
Also, because the thrust arm is absorbing less vibrations from the wheel, you’ll feel the steering wheel vibrate when driving. For the same reason, you can see the wheel “shimmy” when braking, or a sudden jerking and shifting of the wheel.
While this may not seem like an urgent problem, it certainly will be once it starts affecting your driving. Brake failure, wheel misalignment, and uneven tread wear are all side effects of thrust link bushing failure. At this point you’ll have to replace more than just the bushing: you’ll either need to have your brake pads checked, your wheels realigned, or have your tires balanced. In extreme cases, you’ll end up having to do all three, plus replacing the entire thrust link. Since the bushing is lodged into a metal sleeve on the thrust arm, replacing just the bushing is much more difficult and labor intensive than simply replacing the arm altogether.
While aggressive driving will wear out your thrust arm bushings faster than usual, wear and tear on this part of the suspension is fairly common. However, if you ignore the initial signs that the bushings on your thrust links are going bad, you will certainly pay a hefty bill from the damages it can cause, but if you are mindful and bring your Mercedes to a certified technician when you notice the signs, your Mercedes will be easily repaired. This is also why routine maintenance and checks for wear can save you money in the long run.
