Complaints about unusual sounds are frequent. Could this be due to worn-out bearings o r insufficient lubrication?

✅ Yes — drivers report:

Grinding while shifting usually a synchronizer issue

Whining o r humming during acceleration often due to worn bearings o r low oil

⚙️ Possible causes:

Worn input/output shaft bearings

Dry o r under-lubricated gears

Bad alignment of gear teeth

🎧 Mechanics often trace these sounds to poor assembly tolerances o r lack of preventive maintenance.
