It doesn't sound like a problem that can be fixed with new gear oil. Try another shop, they should be able to hear where the sound is coming from when the car is lifted.

Valdemar said:The noise may still be there just quieter when the car is lifted, but if your dealer already tried to put the car in drive while lifted then I guess they tried. Another option is to find a shop that also does smoke check and put the car on a dynamometer. I don't think you can get under the car while it's on a dyno, but it may help to get a better idea where the sound is coming by listening from outside.

I have the exact same sound humming above +/-50 mph and clicking at really low speeds. I have brought it into Nissan three times and two different dealerships and none of them have it fixed.

I purchase a mini camera to record the noise of my car under drive conditions.
In this vídeo the camera are in front right chassis, close to the right drive shaft.

Ear with special attention from second 53 in the aceleration. For me its so clear the noise. What is your opinion? Could be joint kit of the transmission?
Best regards.

Have you checked if there is rust on your disks brakes. The sound seems to be more loud, I suppose after you brake, before accelerating. This is the opinion of my brother, a mechanic, after hearing yours recordings.
Nubo said:It's possible as the bearings will be loaded when under acceleration. First thing I would check is whether or not there is sufficient lubricant. This is done by removing the filler plug and checking with a finger. Likewise, check the axle joints to make sure the rubber boots are intact. Any cracks or damage to the rubber boots can allow the internal grease to become contaminated. If a bearing is damaged it's probably a labor-intensive project of working your way in from the wheel and checking for rough or loose bearings. Get a copy of the service manual.
Nubo said:You might try several runs with that camera, moving it in steps from the wheel area to the gearbox area, and then compare the recordings to see where the noise seems loudest. Might help locate a bit better.

After a long process to dignosis the problem of the noise my Leaf NISSAN came to the conclusion that it would really be a gear reduction problem. Nissan Europa has taken over the repair under the 5-year warranty or 100,000 km.
It was replaced last week and the car is spotless now. Thank you for your help.
