What Causes the Noise in Newly Replaced Shock Absorbers?
4 Answers
Shock absorbers may produce abnormal noises due to improper installation of the new shock absorbers, quality issues with the new shock absorbers, or the shock absorbers not being original equipment manufacturer (OEM) parts. Below are solutions for shock absorber noise: 1. If none of the above reasons apply, you can also check whether the suspension bushings have aged, as worn suspension bushings can cause suspension looseness, leading to a gurgling noise from the shock absorbers. 2. If the shock absorber spring is deformed, it can also cause noise. In this case, simply replacing the shock absorber spring will resolve the issue. 3. The noise from the shock absorber might actually be from the wheel bearings. If this is the case, replacing them directly is the solution. It's important to note that if the shock absorber is faulty, it must be replaced, as it cannot be repaired.
I just got new shock absorbers installed and they're making noise. The most common issue is improper installation. If the bolts aren't tightened properly or aligned correctly, they'll produce squeaking sounds while driving due to excessive friction between components. Not cleaning the mounting surfaces thoroughly during installation, leaving residual grease or debris, can also cause noise. Additionally, if the springs or other suspension parts aren't properly matched, the shock absorbers won't function normally and may create noises. I recommend immediately returning to the installation shop to have the mechanic recheck bolt tightness and inspect bracket positioning. If the noise persists, it might indicate manufacturing defects in the shock absorbers themselves. Addressing this early can prevent bumpy driving conditions.
After I installed new shock absorbers last time, there was abnormal noise, which could be due to several reasons. First, the mounting bolts might be loose, causing a scary rattling sound while driving. Second, it could be a quality issue with the shock absorbers, such as cheap ones with poorly secured internal components. Third, surrounding parts like control arms might be worn out, affecting the shock absorber's performance. From my experience, I suggest first checking if the bolts are tight yourself. If that doesn't solve the issue, take it to a repair shop for professional testing with specialized tools. Prolonged abnormal noise can wear out other parts and affect overall stability, so don't ignore it. It's normal for new parts to need a few weeks to break in, but if the noise persists continuously, a thorough inspection is necessary.
New shock absorber noise usually stems from incorrect installation or non-compliant parts. Loose bolts cause friction noise during movement, or misaligned shock absorber mounts fail to properly dampen vibrations. This is not just a noise issue but can also lead to body sway, affecting safe driving. I believe it's crucial to have it addressed by a professional shop promptly to avoid accident risks. Performing a dynamic balance test after replacement is also essential.
