Hello everyone, haven't been back in a while and I hope everyone is well. the steering in my 1999 C230K has developed a moaning noise that comes from the engine bay when I turn the steering wheel at very low speeds (pulling into or out of a parking space mainly) It's annoying and pretty loud. Is the power steering pump starting to go out? or is there some sort of leak in the system? I haven't found any dripping or anything like that. during normal driving, the steering is perfect. Thank in advance for reading!
