Leading evidence: 'Run 35k miles only' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Fill since the car assembled,, level is ok,, dealer wouldn't' (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.

the Tip fluid is factory fill since the car assembled,, level is ok,, dealer wouldn't change it before 60k miles.

Suggestion
If the noise changes appears to be tied to the car accelerating or deaccelerating -- under closed throttle coast down -- then the rear end (differential) comes under strong suspicion.
Replace noticably a wheel bearing becomes more likely

When safe to do so weaving the car rather sharply first one direction then the other if this makes the noise change noticably a wheel bearing becomes more likely.

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.

my car has a low pitch humming/whining noise,, i guess from rear end,,
it happens @ 45-50MPH on 3rd and 4th gear,, and @ 35-40MPH on 5th gear,,
the car ran 35k miles only,,
any ideas?
If noise constant under throttle or coasting a wheel bearing. When safe to do so weaving the car rather sharply first one direction then the other if this makes the noise change noticably a wheel bearing becomes more likely.
If the noise changes appears to be tied to the car accelerating or deaccelerating -- under closed throttle coast down -- then the rear end (differential) comes under strong suspicion.
Added: The noise could be transmission related. The Tip if low on fluid or with too old fluid or the wrong kind can make noises. Where safe and noise present release gas and shift transmission into neutral. This almost eliminates the tranmission from the equation.
Are tires inflated properly? How old are the tires? Proper (N-rate) tires can get hard with age and heat cycles and when they wear make a heck of a racket.
Are tires the right kind of tires? N-rated? Same front and back, side to side?
Different brands/styles of tires can make different amounts of noise. If tires the cause of the noise my experience is the noise will be present or more pronounced on some road surfaces while absent or barely discernible on other road surfaces.
If the noise does not appear to be connected to road speed but appears to be tied to engine speed, could be something engine related, or accessory drive related. Beyond that...
Is the same car with periodic rpm drop? If so then I think the car's possessed!
Sincerely,
Macster.
As usual, Macster has a lot of good suggestions to investigate.
Are you sure that the noise goes away above those speeds? My pinion bearing was going and the spyder gears were pitted in my transmission and it produced a similar effect, most noticeably in 4th, 5th and 6th gears under moderate engine load. However, the whine was also audible at constant speed as well. I hope that it is not that for you.
the noise is present in speed ranges i specified in both accelerating and decelerating but,,to higher pitch on acceleration,, to lower pitch on deceleration,,
the noise only happens if i traveled really slowly through the speedometer,,
the Tip fluid is factory fill since the car assembled,, level is ok,, dealer wouldn't change it before 60k miles.
my tires are brand new, Y-rated and inflated @ 35 psi
i, totally, agree!
Based on the info you've provided I'm going with the differential.
But you're still faced with having to have some qualified person make his own diagnosis and then acting upon that to fix the problem. Knowing what the problem is -- even assuming I'm right (and my confidence level is not that high) -- is not going to make the problem go away.
The car is need of attention by a qualified Porche technician.
Or, the car needs a young priest and an old priest.
Sincerely,
Macster.
kj217 my attitude is the car has a drive train and is going to make noise. After multitude of sport and performance cars I expect to have gearing noises. It aint no big thang maannn. Well unless you get clunking and and dinging noises.
What happend to the "I have the same sounds coming from the passenger seat, it's the wife" comments?
Is it a hissing or whining sound? My car started hissing, it's the power steering, next thing going I guess ...
My power steering has been making noise for around a month. No leaks, just letting me know its getting ready to retire. It some what sounds like gear whine noise. I'm telling you just in case its the only reason you hear it is because you are at lower noise levels of the engine and exhaust with the steering pump noise elivated.
Although you might remember whining noises from behind the car also has symptoms of flashing blue and or red lights.
Sorry to resurect a rather old thread but in the spirit of not starting a new one, may i ask what the conclusion is for the whinning/humming sound? Was it the low level tip tranny fluid or the diff/diff oil? I have the same posessed car :-) ive searcged other forums and found a few similar issues but yhey never had a conclusion. Is this a common Porsche sound?
