SKF Bearing Kit – Rotor (Electric Motor) – Hyundai Kona / Kia Niro EV (2019-2023)

Repair kit specific for the electric motor rotor of first-generation Hyundai Kona EV and Kia Niro EV (approx. 2019‑2023).

A known defect in these drive units is the passage of stray currents through the original steel rotor bearings, causing micro-welds and premature wear (pitting). The main symptom is a high-pitched hum or whine during acceleration and deceleration. This kit solves the root problem by using hybrid bearings.
