Guess those that question using a small amount of 90 gear oil have never heard of oil bath wheel bearings where that's all that's used.
I've never heard of putting 90 weight oil on to loosen up old grease. I've just always re-did the bearings if questionable. Being I've already jacked trailer up, pulled the hub etc.
You would think by now bearings and tires on anything towed would be as good as the TV. If nothing else the axle manufactures could put some type of inspection port on back side, so you didn't have to pull hub.
As far as oil bath goes...If they made any for smaller sizes (RV size) I bet they would be better system. The only time we messed with them at work, was when they leaked or got crunched.
But if I was starting out on a 2,000 mile trip with bearings that haven't been re-done in 7 years, I would re-pack and be done with it.
