Whining Noise Identification

[thriveordie]

Purchased 2019 Wrangler Sport Unlimited this past October with 15k miles/1 owner and clean history per KBB. There has been a whining noise that can be heard when idling, low speeds, and increases in volume when turning wheels. I instantly thought power steering so took it to the dealership with them telling me no issues/concerns and no identification. Took it to a local mechanic more recently with them also saying no concern and belief is that it’s the alternator however couldn't identify sound without engine disassembly.

It has been driving fine and I have heard this same sound on a few other Wranglers but genuinely curious about what is causing it.

That whining is normal. The electric power steering system will make this noise all the time when turning the wheel.

Interesting but glad you’re the third person suggesting no issue. But it doesn’t seem to happen to all Wranglers correct?

All Wranglers with a stock steering pump (Jeep JL's and JT's) will make this noise.

The JK doesn't make it because it uses an engine driven pump and not electric.

Thank you for the clarification.
