I repacked the bearings last winter and they were fine at that point, but I plan to replace them this time around. I currently have 15K miles on the trailer and one more trip planned in a couple of weeks. I have the Timken bearings to replace them with ready to go. Like you, I purchased a bearing packer and it worked well. Also when we got our trailer I found out that the tires were not balanced. I contacted Jason and he said the tires were supposed to be balanced, but the supplier had failed to balance the tires. I took it to a tire dealership and got them balanced. I think it was something that was just related to the time we got our trailers. Ours is a 2020 that we picked up about the same time as you based on our hull number, 676.
