whining, but you change to 4th and the noise starts immediately ?

That is strange, because the 4th and 5th gears use different sets
in the gearbox, but you get no noise in 3rd or other gears ???

Does the noise remain the same with your foot on the gas and off
the gas ? If going uphill in 4th the noise remains the same ?

Yes it starts in 4 th.
If i go in example at 50 kph in 3rd i hear no noise but if i do the same in 4th i hear the noise.
The noise decrease with my foot off and increase with my foot on.
I've just called the guy who installed my diff and he said that he didn't checked the contact pattern.
This is what i have:
It is located on the top heel drive side and i think it's a bad contact pattern.
Do i need to decrease backlash or add the thicker shim to the pinion ?
I did these researches on the net and now i understand.
