Sounds like the transmission is whining, maybe the orbital gear inside the transmission or even the torque converter.

How are the transmission fluid levels, up?
How are the differential front and back fluid levels, up?

If you're accurately hearing the problem, maybe the front 4 wheel drive transaxle is making this sound, but if you're not in 4 wheel drive this makes no sense because the front should be unlocked or locked automatically, if that's the way it works.

There is a differential carrier assembly in the front:
Differential Carrier Assembly Removal & Installation To Remove:

  1. Turn the steering wheel all the way to the left.
  2. Raise and safely support the vehicle.
  3. Place jack or utility stands at the rear end of the vehicle.
  4. Remove the engine protection shield and front differential carrier assembly shield, if equipped.
  5. Drain the fluid from the differential carrier.
  6. Remove the front drive shaft from the differential carrier assembly.
  7. Remove the relay rod.
  8. Support the differential carrier with a transmission jack or equivalent.
  9. Remove the wheel drive shaft inboard flange bolts, both sides.
  10. Disconnect the electrical connector and wiring from the actuator and carrier assembly, if equipped.
  11. Disconnect the vent hose from the differential carrier.
  12. Remove the inner axle housing nuts and washers from the bracket.
  13. Remove the differential carrier upper mounting bolt and the nut.
  14. Pivot the differential carrier assembly forward and down on the lower mount bolt while supported by the transmission jack.
  15. Secure the differential carrier assembly to the jack.
  16. Remove the differential carrier lower mounting bolt and the nut.
  17. Remove the differential carrier assembly.
To Install:
  1. Install the differential carrier assembly.
  2. Install the differential carrier assembly lower mounting bolt and the nut. Do not tighten the bolt at this time.
  3. Pivot the differential carrier assembly up and back on the lower mount bolt while supported with the jack.
  4. Install the differential carrier assembly upper mounting bolt and the nut.
  5. Install the inner axle housing washers and nuts to the bracket.

The only way to accurately diagnose this is in person. There are not any TSB's on this condition. If you have gear whinning or a pully issue is hard to say at this point. Alll anyone can do here is guess aand a guess will not fix it.

    I am aware of that but unless this truck is on a rack noone will be able to isolate the noise without actually listening. For all we know you could have a wheel bearing noise, but if it is a front differential noise, special tools will be needed to rebuild it correctly or else you will end up with the same problem. Also the cover will need to be removed to inspect for gear deterioration and play. Also if you remove the front driveshaft this will take the stress off the dif and if the noise goes away then you most likley will need to rebuild it.

2002 dodge durango whinning noise will your


Thank you for getting back to me. I would like you to check your transmission fluid. start the engine and let it warm up at idle speed for about 15 min and check the fluid. It sounds like you do not have enough in it, there for the whining noise with increase of speed since your transmission is speeding up with the rate of your vehicle. If this does not help and the problem persist please let me know. If the noise you were hearing was coming from the u joints of the vehicle it would not make a whining noise with increase of speed. The u joints will only make a noise when they are going bad when the vehicle is shifted into any gear from the shifter( EX: park to drive, park to reverse ECT.)

Car makes a low pitch sound starting at 30mph & getting louder as speed increases. 1999 Buick Park Avenue Ultra w/ 3.8liter.


Check for uneven tire wear, make sure the wheels are properly balanced, check for proper tire inflation.
Low pitched noise that increases with speed is related to tires, wheel bearings, etc. Start with the easy and cheap remedies first... tire inflation, wear etc.

2004 Chrysler Crossfire 25,000 mls auto, road hum noise


MOST of the hums after a while come from the diff as the back axle does the driving and almost all its life runs the same way except when going in reverse ,is the rear diff meshing and worn on both the crownwheel and the pinion and the humming gets slightly louder the faster you go and almost goes when almost stopped and this can also be the slight vibration you get so get the diff oil drained and refilled and check if there is any metal in the oil when drained if so thats your problem But it will last for years like that..Let me know how you get on RON

Low level growling noise at rt. front wheel increases with speed. No change if in or out of gear. Can start hearing noise begining about 38 mph. very slight vibration Car has 77,000 miles and is well...


first rotate the tires see if there is a change. If that does not have a desirable effect there may be a worn wheel bearing,take note if the sound or vibration gets louder as you turn a corner, try left turns as well as right turns if the noise increases it is a wheel bearing.
