It sounds like right now you are at the mercy of a shop doing it correctly. You need an rv shop or trailer sales and repair.
The bearings need to be removed and washed of all the old grease to be properly inspected. The bearings should be perfect looking and smooth. I always look at them with a magnifying glass. They wont instantly go from good to bad. They will slowly start to look rough or very slightly pitted. They will progress with pitting and form larger rough areas. Another place where I have seen bearing wear that can be over looked is down in the inner part of the race. The bearing rollers are held in a sheet metal cage. You need to slowly roll the rollers and look closely down into the inner surface as it will sometimes start to pit without the rollers looking nearly as bad.
New races will have honed swirl like look to them. Page 8 in this link starts showing stages and causes of wear.
I say all that because it's not wipe em off, grease em up and throw em in. My bearings had been serviced by the previous owner and I serviced them before I used it. It had a total of somewhere between 15,000 and 20,000 miles on it and I found one wheel with signs of wear this spring so put all new bearings in. 4 sets from Etrailer were about $75.00. I'll run them 2 years and do it again. If the frig breaks or the ac quits or you blow a tire, you can limp into a campground or make it home. If you smoke an axle you aint going anywhere. Zero tolerance and most important issue of all. Well....maybe other then having the rig separate from the TV. But then, having a wheel pass you and kill someone isn't good either.
This bearing came out of my sons 2008 Rockwood TT with unknown miles in 2014.
Yes, the dang oldman is always on them if they did this or that. They are ez lube and he did grease them enough. This bearing would have gone into melt down before long. I replaced all of them.
