It depends on the severity of the problem:

✅ Repair if:

Only minor components like brushes o r voltage regulators are damaged.
The alternator is original Toyota OEM and still in relatively good condition.
Cost of repair is significantly lower than replacement.

🚫 Replace if:

The alternator has major issues burned-out stator, failed bearings.
Frequent breakdowns suggest its near the end of its lifespan.
After repair, voltage output is still inconsistent.

Recommendation: If an OEM alternator is still repairable, fixing it is a good option. Otherwise, a high-quality replacement is best.
