Motor bearing replacement
Replace worn motor bearings — cures whining noise.
Motor bearing replacement is a motor & drivetrain service from ev.care, priced at a fixed ₹4,999 and booked for a 4 hours bench slot. Replace worn motor bearings — cures whining noise. Every measurement is recorded against an OEM baseline so a number on its own can be interpreted in context rather than guessed at. If we surface something outside the scope of this service we pause, quote it separately, and let you decide — no surprises on the invoice.
What's included
- Motor removal
- Bearing press-out + clean
- OEM-spec bearing fit (SKF/NSK)
- Seal replacement
- Test spin
Why this matters
Why owners book this: skipping it risks a controller fault that becomes a tow rather than a workshop visit. A ₹4,999 workshop slot today is the cheapest insurance you can buy against that outcome.
How it works
- 1
Drive-unit baseline (current, vibration, sound) is captured first.
- 2
Inverter and motor are tested in their natural operating envelope.
- 3
Mechanical inspection is done with the unit in-place where possible.
