How Often Should the Shock Absorber Top Mount Be Replaced?
2 Answers
The shock absorber top mount does not have a fixed replacement interval; it needs to be replaced as soon as it is damaged. The connection point between the car's shock absorber and the body is equipped with a buffer rubber, also known as the shock absorber top mount, which serves to cushion vibrations, thereby enhancing the comfort of the vehicle. During the operation of the shock absorber, the impact generated by the road surface is converted into the repeated bouncing motion of the spring by the shock absorber spring. The shock absorber then refines and accelerates the attenuation of the spring's inherent vibration, with the shock absorber top mount serving as the final buffer to transmit the force to the car body. If the top mount is damaged, abnormal noises may occur when the car passes over speed bumps or rough roads.
I've been driving for over ten years, often hauling goods on rough roads, and the strut mount has failed several times. Actually, there's no fixed replacement interval for this part—it mainly depends on your driving habits. For example, if you frequently drive on gravel roads, the strut mount wears out faster and might crack after just a year or two. When I start feeling steering wheel vibrations or hear squeaking noises, I know it's time for a replacement. During routine maintenance, I always ask the repair shop to check if the strut mount is deformed or cracked, so I don’t end up damaging the shock absorbers and spending more later. Safety comes first, so I make it a habit to inspect it quarterly to avoid breakdowns on the road. Remember, the lifespan of a strut mount varies by driver—staying vigilant saves a lot of hassle.
