Stabilizer bar bushings are fixed in cars in order to reduce road noise, absorb bumps and cracks in roads while delivering a softer ride. The stabilizer bar is also supported with rubber bushings that keep the vehicle’s body from rolling as it navigates turns.
When these stabilizer bar bushings are worn out, the warning signs can range from subtle noises to significant problems with steering and handling, potentially leading to vehicle accidents and other unpredictable difficulties in driving.
Having driven your car for a while, you most probably have a clear understanding of how your car handles on the road. One of the easiest ways of diagnosing a problem with the stabilizer bar bushings is when the handling seems slow to respond, especially when you make quick turns around bends and corners in your vehicle. If you turn into a corner and the vehicle seems less stable than it has been previously, this is an indication of bushings being worn and needing replacement.
When the bushings become torn, worn out or completely break, the stabilizer bar itself will become unstable and cause a rattling clunking sound while you are driving. The noise will get progressively louder when you steer the car in either direction or when you are driving on a rough road. Typically the noise will come from the front of your vehicle. This sound is noticeable while you are driving over bumps, making aggressive turns to the left or right, or if you drive over a pothole. This noise is typically caused by a stabilizer bar bushing that is not properly lubricated due to metal-on-metal contact.
When all the above mentioned signs begin to appear while you are driving, it is important to take your car to a garage for replacement of the stabilizer bar bushings. When replacements are not made, your car will become unstable on the road increasing the chances of losing control and causing accidents.
