Why does the car shake more after replacing new engine mounts?
2 Answers
The reasons for increased vibration after replacing new engine mounts are as follows: 1. The engine mount pads were not replaced simultaneously. There are three engine mount pads in total. If only one is replaced, it will disrupt the original vibration damping balance, causing the vehicle to shake more. 2. The engine mount pads are unsuitable. Some vehicle models require specialized engine mount pads. If the pads are unsuitable, they cannot provide effective vibration damping, naturally resulting in more shaking. 3. Other faults may be causing the issue. Check whether the engine oil used is the grade recommended by the manufacturer. Oil that is too thick or too thin can cause engine vibration.
After replacing the engine mount on my car, it actually shakes even worse. This thing is supposed to secure the engine. I thought the old rubber mount was cracked and worn out, so replacing it with a new one would make things smoother, but now the steering wheel vibrates so much it numbs my hands, and the seat feels like a massage chair. Looking back, it's either the aftermarket part is of poor quality with no damping effect, or the mechanic rushed and didn't tighten the screws properly, leaving the mount uncompressed. Experienced drivers have encountered similar issues—sometimes you have to recheck the installation position or switch back to OEM parts to stabilize things. Severe engine vibration is no small matter; it can wear out other components. I suggest going back to the shop for a recheck to rule out other potential issues, like deformed engine mounts or aging parts causing problems.
