Why does the rear shock absorber make a creaking sound?
2 Answers
There are two main reasons why the rear shock absorber makes a creaking sound: 1. Damaged shock absorber: When the vehicle's shock absorber is damaged, the coordination between its components is compromised, causing it to produce a creaking noise when working on bumpy roads. 2. Damaged shock spring: The top rubber mount of the front shock absorber, made of rubber material, primarily assists the shock absorber and spring in providing cushioning and shock absorption. When the top rubber mount is damaged due to excessive wear, it not only causes noise during operation but also produces sounds when turning the steering wheel while the vehicle is stationary, even if the shock absorber is not in use.
I've been driving for many years and have encountered squeaky rear shock absorbers several times. It's usually due to the aging, wear, or cracking of the rubber bushings on the shock absorbers, which create noise when rubbing. Loose mounting bolts are also a common cause—you can feel the looseness by shaking the control arm by hand. Long-term neglect can make the entire suspension system loose, affecting handling stability, especially during turns or at high speeds, increasing the risk of wobbling. I recommend getting it checked as soon as possible to see if it just needs lubrication or part replacement, to avoid uneven tire wear. Driving less on bumpy roads can reduce stress, prolong part lifespan, and maintain vehicle safety.
