Why is there a friction sound when stepping on the accelerator?
1 Answers
The following are the reasons for the friction sound when stepping on the accelerator: 1. Car half-shaft failure: Due to long-term torsional fatigue and impact forces, the car's half-shaft is prone to bending, twisting, breaking, as well as wear or skewing of the spline teeth. This can cause the car to shake rhythmically in a certain speed range when accelerating, accompanied by a clicking sound. The shaking disappears or lessens when the accelerator is released. 2. Loose engine belt: A slipping belt will produce a hissing sound. Once the belt slips, it leads to friction and high temperatures, causing the belt to stretch further, which worsens the slipping, creating a vicious cycle. In this case, it is necessary to go to a repair shop to adjust the belt.
