Silent blocks in car suspension systems can fail due to several factors that cause premature wear. One common cause is incorrect installation under preload, which places constant stress on the bushing, leading to accelerated wear and eventual failure. The Shore A hardness of the rubber material is also crucial; if it’s too hard or too soft, the bushing may not absorb vibrations effectively or could degrade quickly under load.
Optionally, cavities within the bushing are designed to accommodate flex and reduce stress. If these cavities are poorly designed or the bushing lacks them, the material can suffer from excessive compression and deformation, leading to cracking or tearing over time. Proper material selection, design, and installation are essential to ensure the longevity and performance of silent blocks in suspension systems.
For example a hydraulic silent block can fail due to a leakage of the oil by a tear or infiltration into the rubber.
Re-engineered technology.
Sidem’s success is built on 90+ years of expertise in engineering and manufacturing of steering and suspension parts. When it comes to the aftermarket, we start from the OE part as the reference point. Based on our experience, we look if we can make the part better performing for a longer lifespan, more safety, higher comfort or an easier installation. If a part is improved compared to OE, it is called ‘Sidem Re-engineered Technology’.
