Whining noise when turning at low speeds

[speed858]

So here is my issue:

When first starting the car and turning left or right out of a parking spot, I get a loud whining sound.

This sound goes away when turning above 15 MPH and when the clutch isn't engaged.

I took it to carmax since I have a warranty with them and they replaced the power steering pump.

Problem still persisted and now carmax is stumped. They are recommending that I take it to a transmission expert.

What are your thoughts?

Steering rack? Sure there's not a leak?

I checked it and carmax checked it.

No leaks around it. I was thinking about replacing my transmission fluid with the Motorcraft Xt-M5-Q5.

Think that would help?

it only makes the sound when turning and the clutch is engaged? not with just the clutch engaged and doing nothing??

 

[speed858]

Yep, only when turning.

The can push the clutch while doing nothing and no sound.

So sounds like only when there is a load on it.

Limited Slip differential. A change of fluid might help but I would stick to the factory fluid.

This, though i did switch to the motorcraft synthetic...good stuff.

Alright, I will try changing the fluid out.

Let you guys know the results.

Did changing the fluid resolve the issues? I have the same issue in my car too. It always seems to make the noise at low speed when doing a sharp left or right turn. This always happens when turning into a parking spot or doing a u-turn. I don't recall this occurring when I first bought the car, but it seems to start after about 40-50k. Also, similar to the other post, the noise does not occur if I push in the clutch when turning.

Problem resolved! I put in the Motorcraft synthetic fluid and it works great now!

Thanks for all the help!

Did you add the Friction Modifier?

This is why you need friction modifier:

"I still get some whine at low turning speed with the Motorcraft XT-M5-QS. Example when i'm driving around in a parking lot looking for a spot.

Do the rest of you guys get any whine at all?"

 

[speed858]

I didn't add it at all.

It's working great without it.

Changing the tranny oil to MT-90 didn't seem to fix the issue. Did the noise stop right away, or is there some sort of break-in period. Maybe I should of use the Motorcraft brand instead, but I will have to try that friction modifier stuff next.

 

[speed858]

Yeah only the motorcraft one works. It's immediate.
