What Causes the Gearbox Noise in Sagitar?
2 Answers
Here are the specific reasons for gearbox noise in Sagitar: Bearing wear and damage: When bearings wear out, the gap increases and the fit accuracy decreases; when bearings are damaged, abnormal sounds occur as they cannot operate normally, potentially damaging transmission components and worsening the fault. Long-term lack of gearbox oil change: Thickened gearbox oil reduces fluidity, eliminating the protective layer between components, leading to direct friction that accelerates mechanical wear and causes noise. Use of inferior gearbox oil: Inferior gearbox oil has poor heat resistance, easily oxidizes, and forms sludge and residue that clog filters and oil passages, increasing internal friction and resulting in vehicle noise.
I've been driving a Sagitar for several years and encountered transmission noise issues, which is really annoying. Possible causes include insufficient or deteriorated transmission fluid, leading to increased friction between parts due to lack of lubrication. It could also be internal wear, such as damaged gears or bearings, which is common in high-mileage vehicles. Regular fluid changes are crucial, recommended every 20,000 kilometers or two years. If the noise is a clunking or grinding sound, it's likely a mechanical failure. Don't ignore safety concerns; the noise becomes more noticeable at high speeds, so pull over and check promptly. I've found that timely maintenance can prevent many issues, with regular fluid changes and using genuine fluids being key. Otherwise, minor problems can escalate into major repairs. Experience tells me it's best to get a professional diagnosis at a specialized repair shop rather than attempting DIY fixes, to avoid unnecessary expenses.
