What causes the abnormal noise in the 14th-generation Sylphy?
2 Answers
The causes of abnormal noise in the 14th-generation Sylphy are as follows: 1. Half-shaft issue: The half-shaft of the car, under long-term torsional fatigue and impact forces, is prone to bending, twisting, breaking, as well as wear or skewing of the spline teeth. This can cause the car's front end to shake rhythmically when accelerating within a certain speed range, accompanied by noise. The shaking disappears or lessens when the accelerator is released. 2. Loose engine belt: A slipping belt will produce abnormal noise. Once the belt slips, the resulting friction heat will cause the belt to stretch further, leading to more severe slipping and creating a vicious cycle.
I've been driving the 14th-generation Sylphy for several years, and encountering strange noises is quite common. Generally, you need to identify the cause by location. For example, if the front wheels squeak when going over speed bumps, it's mostly due to aging suspension bushings or loose shock absorbers, as these parts wear and deform over time. The interior also tends to make noises, like door seal shrinkage or plastic friction sounds from the dashboard, especially noticeable in cold weather due to thermal expansion and contraction. Sometimes, there's a rattling noise at high speeds, which requires checking tire balance or bearing issues. Last time my car had a similar problem, the mechanic said it was due to improperly installed brake pads. He suggested first driving slowly on a quiet road to listen for the source, recording the scenario with a video, and not delaying until driving on the highway causes trouble. These minor issues aren't expensive to fix—replacing the parts usually quiets them down. Remember, regular maintenance can prevent a lot of headaches.
