I own a bunch of different trailers and have not even repacked bearings much less replaced in years. I do jack the axle and wiggle the tire to check the amount of play in the bearings when my IR temp gun shows it's hotter than the other wheel bearings. If it's got excessive play I'll tighten when I pull the cap off to look at the grease. If the grease is old and hard I put some 90 weight gear oil in the cap and put it back on quickly. Only been doing this for 40 years. Your mileage may vary.
Yikes, this is not good advise or proper bearing service unless you want to be parking your trailer on the side of the highway.
Repacking bearings is so easy, there is no reason not to do it every two or three years. There are lots of U-Tube videos if you are unsure how to do it. Use a good high temp bearing grease like Mystik JT-6 high temp, not gear lube.
