whining noise when accelerating
 
good day to everyone

i just got my jeep last month and been wondering what's the whining noise when accelerating at 100kph and its gets louder until i reach 140kph it stops. it sound like i have a TC or SC. and when i let off my foot on gas pedal, i didn't hear any whining noise and when i let my foot on the gas pedal again, i can hear that noise again.

can anybody heard this noise too?

btw, just replaced differential gear oil with lucas 75w-140 and added friction modifier but i still hear that whining noise. i took off the cover and drain the oil, and found some metal shavings on the oil.

any feedback is highly appreciated...

thanks and more power.

Possibly bearings. Determine if its front or rear, i remember that happened to my old zj.

were your diff's making noise before you changed the oil?

When I had diff oil changed, it was overfilled and it did make some noise. Since I have drained some oil, the noise is gone.

yeah, it making the same noise before i changed my diff oil.

in addition to that, i feel some vibration (wwrrr... wwrrrr..) in the floor and in the seat as the noise faded when i reached 140kph and when i gas it up until 160kph the noise and vibration totally gone...

any more ideas?

thanks
