Re-Greasing Ceiling Fan Bearings

I wanted to try, and see whether adding new grease to old ceiling fan bearings can make the fan quiet again as a new set of bearings cost about the same to what I paid for this second hand ceiling fan. This is my 4th time working on Chinese ceiling fan bearings, in which the first 3 attempts all lead to a motor failure, which is why I had to use extra precaution on this one as I really want to preserve the original windings(and not pay the cost to get it rewound).
In the first 3 attempts, I hammered a flathead screwdriver into the gap between the lower, and upper motor shell. The second attempt failed at this stage, when I accidentally hammer the screwdriver hard into the windings. The first, and third attempt failed because I wasn't careful enough at handling the stator once they're out of the motor shells. This time, I screwed 3 long bolts into the blade mounts, and tighten them with the help of a wrench. It pushes the 2 motor shells apart, revealing the windings, and rotor.
I wasn't surprised at all when I saw a set of unsealed bearings under the motor shells. Most, if not all cheaply made Chinese ceiling fans don't provide seals on the bearings to cut cost. With no seals to penetrate, I immediately went to town, and fill the bearing cavities with goopy, sticky grease, which hopefully will last 15 or more years. Reassembly was a bit harder than I anticipated, but it was nothing I couldn't tackle.
The end result is not as good as I'd hoped. Most likely because I didn't get rid of the old grease packed with impurities. But a bit of the whizzing dry bearing sound is gone, so that's something. Oh and, don't worry about the scratches on the paint. The old paint is all gonna be stripped off anyways.
