Change Timken Bearings at 12,000
Understand that the overall consensus is that trailer bearing shuould be replaced around 12,000. Per suggestions of this forum I changed and have been using Timken bearings. Mechanic, who admits he doesn't know anything about travel trailers suggested that due to the high quality of Timken products I may be throwing my money away. He suggested I check with those more experienced. I told him I had the perfect Forum

clean, inspect, repack...replace if they fail inspection....12,000 miles or every two years is a good interval in my experience for my usage.

I have always yearly or 2 pulled the outer bearing, cleaned, and inspected. Obvious signs of pitting or other deformities are cause for rejection and replacement. Discoloration from overheat are also of concern. Only pulled the inner bearing if there was a problem, of course ensuring it was properly greased. Dont get the just replace them.
Also carried a spare bearing set, seal, and grease; just in case. Hand feel the axles at the caps for heat every stop.

I've not heard that you are supposed to replace them every 12K miles, rather that is the recommended interval to pull them, clean, inspect and repack them. Upon inspection you may decide to replace based on a number of conditions mentioned by earlier posters. I would agree it is a waste of money if they are being arbitrarily replaced that frequently. Properly maintained you can get a lot of miles out of even a cheap set of bearings.

No need to replace bearings unless they need to be. Here's a link to what to look for and to possibly diagnose bearing failure.

I have about 30k on my original bearings (made in China to boot). Have a set of Timken in my spares box.

I have over 19,000 miles on my original bearings and they are fine along with my brakes. I have the bearings repacked and inspected along with cleaning the brakes every 12 months.

Forgot to add: I repack ever 2 yrs (or so), in between repacks I pump thru the ez-lube zerks. Sloooowwww and steady while spinning, have had no probs. I do my own bearings, ‘cause I can and mostly ‘cause I’m paranoid I guess.
