My 2000 Toyota 4 Runner has started making a groaning noise when I turn the steering wheel at low speeds (parking and leaving parking spaces). I have checked the power steering fluid and that is not the problem. Is this a lubrication problem or a belt?
The problem might be that the vanes in the power steering pump are beginning to stick allowing power steering fluid to by-pass them. Have a power steering fluid exchange performed and if it’s the pump vanes sticking that should fix it.
where exactly is the noise coming from can you tell?
