Let's start with the basics. 

The car has both new skf bearings fitted. 

The axles have been torqued to 290nm.

Now to the problem. 

When I am setting off from the driver side wheel a sound that could best be discribed as a very angry bee 🐝 is coming out. 

It is not corner dependant and it is masked of when going more than 10km/h.

The sound started approximately 10 minutes after I left the shop on Saturday. 

But I am pretty positive that everything was done properly. 

My father keeps insisting that we did not add enough grease to the cv joint and that is the culprit. 

But I am wondering the cv joints were completely quiet before that. 

Also we use from the 2 flasks of grease 1.5. But the cv joints had a lot of grease in them beforehand. 

Lastly when I rotated the wheel by hand yesterday I could only hear some brake rubbing. Nothing more. 

Look at this photo for a reference about how much grease we added. 

Can you record the noise using a phone attached with a dashboard magnet base to the left wheel arch?

So on the floor next to the clutch. 

Yes I will 

Update. 

The noise got reduced significantly on its own. 

Also it will not occur now when rolling downhill only when accelarting. And it is barely noticeable. 

Will try to record it but I doubt the mic is going to pick up anything.

The noise as you describe it has a high pitch. That can't happen on a low frequency generated by the rotation of a part from the running gear at low speed as you mentioned.

Does the noise happen if you go downhill from stop? With engine stopped, in neutral, ignition key on to be able to steer, and no traffic around you.

 

Might be a circlip for the drive shaft not set properly in its groove. That could somehow make the inner joint rub in the marked area.

 

Or maybe a small pebble got stuck between brake disc and brake pad? Or a stuck caliper?

When in neutral there is no noise.

The one on the drive side cv joint gave us some trouble but it went in after a bit of persuasion it clicked into place.

Is it dangerous or damaging to the car?

When i jacked up the front wheel and rotated by hand the only thing I could hear was some slight brake rubbing nothing more.
Most likely it was the clip or something stuck in there that a part of it broke of or got dislodged.

So we established it is the left(?) drive shaft related. Maybe clutch.

I would jack up the car, put it in 1st gear and rotate the left wheel.

Will do

Got the video(s).
Will upload the best one first.

 

What also is intresting to know it that during the service we may possibly have flipped the location of the cv axles

Not clear what you mean.

About the videos: the noise is strange. Not sure what speed at does it happen. I was under the impression it happens in 1st and 2nd gear.

I still think the best would be to jack the front of the car on 2 stands then start the engine, put it in gear and "drive" trying to make the noise happen.

The best indication as i say is given on the first clip at around 0:51. Preety steep hill going with second gear approx 1500rpm and giving it a lot of gas that rumble like noise is exactly what i am hearing with a varying intensity on the other clips.

I meant the joints sorry.
The left may be on the right and vise versa.
As for the 2 jack stands ive thought of that but it would not make the noise as it will not be under any load generally speaking the smoother you set off the less the noise.
The noise happens when there is torque applied to the wheels (going forwrds) but you wont hear it at higher speeds or at higher engine loads ( meaning that going 20 with 3rd gear and flooring it the noise would be masked by the engine struggling)

You can't swap drive shafts as a whole. They are different lengths. Side note: is the counterweight on the right shaft well fixed?

Do you mean outer CV joint (left) swapped with outer CV joint (right)?

IT WAS MISSING...
Yes I mean exactly that
