Thx guys. I know it is supposed to have a tag on the cover, but I don't know how it looks and it could have fallen. I just did not want to assume.
The oil seemed to, odly, be clean at first, but then brown. It had no visible metal specs.

The wheel bearings, sadly, it seems that I changed then for no reason. I was under the impression that the noise when moving the wheels by hand and even the resistance they had were both signs that the bearings were gone. They also had, very little, but some play in and out.
After replacing, the new bearings turned even stiffer and the noise was just exactly the same. There was no in/out play though.

But, it seems that they weren't has gfar gone as I and my mechanic thought they were. I will post video of the said noise before and after. They sound the same to me and in hindsight, I believe the bearings did not really need replacing, but I will welcome your experienced opinions.
