I checked the power steering level and the level is good.
Leading evidence: 'Check power steering level and the level is good' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'alternator' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Check power steering level and the level is good' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
Of course, no longer hearing the noise could also mean it's any of the parts turned by the moving belt but a noisy /worn bearing can be heard using a mechanic's stethoscope when turned by hand.

Mark the direction of rotation on the drive belt using a paint marker.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Good evening,
Have a question for the group- I noticed a whining/ winding noise coming from the drivers side of the car while I am driving at speeds greater than 20MPH. It starts at 20MPH and 99% sure it remains steady, but can't hear at higher speeds since I just hear the engine, and then it stops when going less than 20MPH.
What could this possibly be and is this safe to drive or do I have to get this to a mechanic ASAP? This car has now become my daily driver for the next 2 weeks until I can get my other car fixed.
I did send this information to my tech, but waiting to hear back, so figured I would do a sanity check and reach out to the group in the meantime.
TIA

Car is a 2001 996 911 automatic transmission. Lol. So the car is working well with no issues. Accelerates fine, car doesn't overheat. Just had the car oil analyzed approximately 3K miles ago and had a health engine with no issues. Had a PPI before i bought it and did not have any red flags - engine and transmission was in good working order.

Rear end of the car drivers side could be passenger as well just notice drivers side while driving.
I do not have a video and not sure if I will be able to get one since only happens when I am driving. Does not happen parked or at idle- have to be going greater than 20MPH.
Well i kinda made that wild guess while u were making that post as u held that info close for several posts......drivetrain noises manifest though other parts but it really could be anything in the drivetrain.....maybe a bad cv?
Yeah, sorry about that. Didn't realize that until late. I definitely do think it is drive train related since it does not do it at idle and does it when car is moving. Just wanted to ensure I can drive it for another week before my other parts come in for my daily driver so that can be fixed.
Hard to tell? Its probably something wearing out but not yet worn out. If its speed related and not rpm related then its not the motor and its probably fine for a while. My original y2k trans was always loud in the pass side rear, i always though that it might be a pinion bearing but it did have over 200k miles on it.
2001 is a five chain engine and will have a distinct sound to it, that some would describe as a �whine.� That would be RPM not speed dependent. Power steering can whine when fluid is low. If it�s new and coming from one side of the car, speed not rpm dependent my guess would be wheel bearing. LHD driver�s side bearing should get louder turning right and quieter turning left.
audio is necessary to get more than wild guesses though.
Thanks. I was thinking possibly brake to close to rotor causing it to make that noise, but it does not screech or anything when I brake, so ruling that one out, but wheel bearing seems possible for sure. I haven�t noticed any difference when I turn the wheel. Only difference is when I drive speeds greater than 20MPH, but I will check to see if RPM as well. I am going to take a closer listen though for now on when I turn to see if there is a difference.
I checked the power steering level and the level is good. A video might be hard to capture since I have do it driving and I don�t have a go pro handy or anything.
It's probably the alternator. How to confirm:
Engine cold.
Remove air filter housing.
Mark the direction of rotation on the drive belt using a paint marker.
Take picture of how belt is routed.
Use a 24mm socket and put it onto the tensioner pulley nut.
Turn clockwise to slacken the belt and take off belt.
Take your tools, refit air filter housing and connect Plug to MAF.
Put belt and tools inside car
Start car and drive up to the speed at which you noticed the sound before and listen for it.
Park up somewhere safe and switch off engine.
Post what you find on rennlist!
Refit belt, taking note of direction of rotation.
Fit airbox and connect plug to MAF.
Of course, no longer hearing the noise could also mean it's any of the parts turned by the moving belt but a noisy /worn bearing can be heard using a mechanic's stethoscope when turned by hand. The noise the generators fan makes requires the appropriate engine speed, however.
HTH.
