Wheel Bearings
I have a 28 ft. TT and had the wheels bearings completely serviced in 2019. I have used the trailer only twice since then for 2 trips of 400 miles total. I would like to make another trip of about eq...

I would really like to see some proof or research/testing done by a reliable source to back up that statement. Having serviced hundreds of semi trailer units and not knowing what grease was used previously, it was a rarity, rarity that a bearing in our fleet of over 10k units ever had a bearing failure. A bearing was only serviced when the unit was brought into the shop for a brake change. That could be anywhere from 1 year or 5 years. Servicing wheel bearings every year is just nonsense. I call malarky on that one.
When did you do all this service work on semi-trailers that used grease in the wheel bearings? My axles from the early '80s all had oil bath bearings.
And most fleets large enough to have shops to do their own service work buy large amounts of the same lube.

inner bearing about the same the outer bearing on the Cutlas is smaller. Weight per wheel about equal 1200lbs 455CI weighing them down (smiles)
Think if you put side by each you would see rollers are bigger/longer than 5000 lb trailer axle.
BTW, line mechanic at Olds dealer when heard GM was going to allow over 400 CID in A body cars starting in '70. Placed order for 455 powered 442. Got home from work draft notice in mail box.
By chance you're not one of those that does an oil change every 3000 miles are you?
Actually no. Twice, the same NTC engine, needed bearings in the spring after mostly setting for winter. Oil sample the 3rd spring warned of contamination. My pickup rarely runs 1000 miles 2 months in a row. I have changed the oil when it had been in there 3 months, but used less than 500 miles.
