Many car owners have a question about where the squeak comes from in the car's suspension. This very unpleasant sound often manifests itself in different situations, but, as a rule, the stabilizer bushings, which have a very large wear, can be the first cause. Such a problem is not new to the practice of many motorists, and it can come from both rubber products and polyurethane products. Therefore, in this article we will get the answer to the question: why do bushings squeak?
What are silentblocks made of?
It should be noted that the most popular and sought-after materials for the manufacture of silent blocks are rubber and polyurethane. Based on the composition, a number of positive qualities can be distinguished in polyurethane that distinguish it from rubber:
But, despite these advantages, a «light» squeak can be heard during intensive driving, even after installing new elements. Therefore, the question arises: why do polyurethane bushings squeak?
There are only two reasons for the suspension squeak, no matter what the load on the car, and no matter what the road is under the wheels:
The first and most common reason is the discrepancy between the diameters of the openings of the elements and the stabilizer itself. Many auto repairers who have practice in this problem specify the fact that the diameter of the bushing must necessarily be at least 1 mm smaller. The distance where particles of dust, water and dirt can get is the cause of the squeak, and the main problem is why new bushings squeak on a car. The second less popular reason is the lack of lubrication on polyurethane bushings. Bushings squeak after replacement with a limited amount of lubricant. Bushings can be lubricated both inside and out, to the surprise of many car owners. This process is very simple. It requires lubrication and a little experience.
And here the question arises: if bushings squeak, how to lubricate them in order not only to eliminate the squeak, but also to increase their service life? You can find the most suitable types of lubricant for these elements on our website. Their elasticity and density is able to fill these voids between the stabilizer and the bushing as much as possible. After lubricating these parts of the car, you can safely test the suspension for squeak in the «idle» mode of the car. Also, don't lose sight of regular inspections of the stabilizer, wear of bushings and bushings.
But whatever the reasons for the appearance of a squeak and noise of a car are not a reality, it's very important to buy high-quality spare parts. A proven company that produces high-quality components for cars, including polyurethane bushings, is PoliPro. The company has won the trust of many car owners in Ukraine, thereby becoming a leader among manufacturers of polyurethane products for cars.
