What Causes Car Gear Grinding?
2 Answers
The following are the reasons that cause car gear grinding: 1. Forcing the gear into place without depressing the clutch, or forcing the gear out without depressing the clutch. 2. Completely releasing the clutch before the gear shifting is completed, which will result in a gear grinding noise. 3. Try to avoid this as much as possible, as it will wear out the gears. 4. Clutch failure, which is a mechanical failure of the clutch that prevents it from disengaging properly, causing the gears to make a rattling noise. 5. Operational reasons, which means the clutch is not used correctly. In this case, attempting to engage the gear will result in a clicking noise and failure to engage. Shifting gears under these conditions can cause damage to the transmission.
Having driven for decades, I've encountered major gear issues several times, often due to insufficient maintenance. Aging or insufficient gear oil leads to inadequate lubrication, causing severe surface wear from friction; overloading is another common factor, putting excessive strain on the drivetrain and accelerating damage. In terms of driving habits, aggressive acceleration with sudden throttle inputs can cause gear impact and fractures; environmental factors like moisture intrusion leading to rust also play a role. Repairs are troublesome and costly, so I insist on checking oil levels and quality every six months, driving as smoothly and gently as possible to prevent these minor issues. Developing good habits saves a lot on repair costs and, more importantly, ensures driving safety, avoiding the worry of breakdowns on the road.
