Common Problems with the Audi A6 Control Arm
Your vehicle's wheel hubs are connected to the chassis through the triangular-shaped suspension component called the control arm. It is one of the most important parts of your Audi A6's independent suspension system. Your car's control arm is the one primarily responsible in reducing the vibration transference and preventing the contact between the arms and chassis which are both made of metal. Getting this component worn out and damaged can cause problems in your suspension system. Here are a few of the most common problems that you might experience with your Audi A6's control arm.
Vibration and shaking of the steering wheel
If you're experiencing vibrations while driving your Audi A6, this could be a sign of a bent, torn, or worn out control arm. These vibrations are more noticeable when you're driving at a freeway because they will get worse at higher speeds. Aside from a damaged or worn out control arm, bad alignment, warped brake rotors, bent wheels, unevenly worn tires, and worn out control arm bushings are also some of the other possible causes of vibrations and shaking of your car's steering wheel.
Loose and imprecise steering
A faulty control arm may also make your steering feel loose and imprecise. Pay close attention on your vehicle's behaviour and movement while you're driving then check how the steering feels like. If you notice that your car wanders back and forth when you're driving it around a series, on corners, and in a straight line , this could be the result of the excessive slop of a worn out control arm bushing. Aside from the loose and imprecise steering, a bad control arm bushing may also cause the when and suspension to move easily and excessively.
Unwanted noise while driving
If the bushings in your Audi A6's driving your car control arms are worn out, you are most likely to hear rattling and clunking noises while driving. These noises are usually more noticeable when you are driving at lower speeds and around corners. However, if the noise you're hearing is a squeaking sound, this could be caused by an intrusion of water or other contamination on your control arm bushings. Make sure to always do a routine maintenance inspection on your bushings and check for flaking, cracking, advanced deterioration, and other signs of wear that can result to unwanted noises.
How to Keep the Audi A6 Control Arm in Top Condition
It may seem like an unimportant component in your car but the control arm of your Audi A6 is an important part of its suspension system. The control arm holds your vehicle's wheel hubs to the chassis while preventing the metal-on-metal contact between the two and reducing vibration transference. This is the component that allows the wheel to move up and down while preventing forward and rearward movement at the same time. A control arm in a bad condition not only affects the overall performance and ride quality of your car, it also puts you and your passengers at risk of accidents on the road. To avoid major problems like this, it is important to take proper care of every part of your car. Here are a few tips on how to keep your control arms in good working condition.
Inspect the bushings regularly.
The bushings in your Audi A6's control arms are responsible in maintaining the proper alignment of your wheels by keeping the control arm in its proper place. Make it a habit to check the bushings in your Audi A6's control arms during your routine maintenance inspections. These bushings will get worn out overtime due to harsh weather conditions and result to excessive tire wear and erratic handling symptoms. To avoid these problems from getting worse, always check your control arm bushings for cracking, flaking, deterioration, and other signs of damage.
Inspect both the upper and lower control arm.
Doing a regular visual inspection on both the upper and lower part of your Audi A6's control arm will help you spot problems easily. Using a floor jack, simply check your upper control arm bushings which are located at the ends of the control arm that is bolted to the frame. If you see that the bushings are split or misaligned, replace them immediately. Do the same inspection for the lower control arm bushings and look for signs of oil saturation, cracking, or splitting. If the damages in the bushings allow the lower control arm to move, have them replaced immediately as well.
Prevent squeaking noise.
Water intrusion and contamination are what causes the squeaking noises coming from the control arm when you're driving over bumps on the road. Aside from that, flaking, cracking, advanced deterioration, and other signs of excessive wear can also result to unwanted noises. Spraying a silicone lubricant on the control arms and bushings during your routine maintenance inspections will help a lot in reducing the undesirable noises.
