It is never relaxing to perceive new sounds on your vehicle. We always might worry and think about the most extreme. But finding out wheel noise on smart fortwo is very often connected to small issue that you can easily eliminate. To help you in this research, our team decided to produce this paper to make your life easier and support you in this task. To do this, we will alternately see what are the distinctive noises that smart fortwo wheels can provoke and to which failures they are associated.
The different wheel noises on smart fortwo and their sources
We will therefore focus on the different types of noise you may feel and their origins.
I listen to grinding wheel noise on smart fortwo from, cardan shaft
The first possibility of grinding wheel noise on your smart fortwo is that you feel a gimbal noise when you are turning significantly, usually at low speed. It is also plausible that you may feel this noise when you pass over speed bumps. You should encounter a noise close to a cracking . It is quite plausible in this case that one or more bellows of your gimbals are dead. In this situation, the joint must be injured and the transmission may fail. Check the state of the joint bellows and replace them if necessary or risk having your vehicle immobilized. If they have holes, they will very fast dry out and fill with dust or stones that will promptly affect the cardan shaft itself, don’t wait to act! In case you have a noise when you pass on damaged roads but the gimbals are not the reason of it, have a look at this guide about suspension noise on smart fortwo to support you find a solution.
I find out a wheel noise smart fortwo when coasting connected to a bearing
One of the other potential causes of signs on the front wheel of your smart fortwo when coasting, may be that one of your bearing is good to be replaced, it will tend to produce a thumping noise that intensifies when it is stressed (turns faster and faster). So make sure to check by taking speed (neutral and window open to hear only the noise of the wheels) that the noise is well located here, if this is the case replace it or them in the near future. If, on the other hand, this noise only manifests itself with an engaged speed, have a look at this guide about loud noises on smart fortwo, you will most likely find a solution to your trouble.
I find out a wheel noise smart fortwo connected to brakes
If you listen to noise from one or both of your wheels, it is highly plausible that it is your pads or discs that are the reason. Indeed, a disc or a set of dead plates will generate a loud metallic noise that you will inevitably feel. To check this, put your vehicle on axle stands, and check the state of your discs and pads by taking off the wheel. If they are involved, replace them quickly , otherwise you will no longer be able to brake. If you feel a metallic noise from your smart fortwo, but the brakes are not the cause, read this guide for more details on this trouble.
I find out a wheel noise smart fortwo connected to faulty wheel alingment
If you feel a noise that may look like a vibration and will increase as you increase speed, it is plausible that your wheel alingment or balancing is the origin of it. Wheel alingment of a vehicle is a fundamental step that is generally done after each tire change. It will ensure that the wheel moves in a perfect axis and therefore that tyre wear is homogeneous and grip, ground contact is ideal. If your balancing weights are missing or incorrectly positioned, your wheels will tend to vibrate a lot and provoke a significant wheel noise on smart fortwo. Examine that your seals are still set up, otherwise go to your garage.
I hear a wheel noise smart fortwo linked to wishbone
Finally, you may experience a noise on your smart fortwo at the wheels, when you accelerate, you brake or in a rather random moment. It is likely that the trigger of this trouble comes from the double wishbone suspension or the direction hinges. Indeed, you will be able to test a damaged double suspension wishbone during the acceleration phases when it will be pushed on side and the car will pull on the outside of the damaged wishbone (right wishbone pulls right) and when braking towards the inside of the same side (left wishbone pulls left). You can also check the condition of the swivel bellows visually, which may disturb the action of changing direction. If you are in one of these cases go to your mechanic.
