FWIW, if the sealing surface of the shaft isn't damaged, you're not going to "blow grease past the seals" if you follow the instructions.

IMO the EZ Lube feature isn't really needed, but it only causes trouble when there are other issues.


Key word , follow .
Yes, that's true. But from my experience, not the most in the world mind you, the bearings will probably fail due to poor assembly where ever they are put together. When I examined mine I was chagrined to discover all the nicks and gouges on the sealing and bearing surfaces of the axle shafts. On a couple of them a half-inch or less closer to the seal lip and it would have been damaged and a potential leak created. I checked them all after that discovery and used a hard stone to deburr and smooth the bearing and sealing surfaces. A poor, poor job was done assembling them.


I’m sure the EZ Lube works for some , I just know for sure when hand packing they are definitely greased properly , and have never had a bearing failure . Fortunately I’ve never gotten a bad bearing or assembly . The only time I blindly towed a fifth wheel not knowing the condition of the axles is when I ordered a new one and picked it up 1600 miles away . No issues , and I didn’t mess with the bearings for a few years , I am definitely not one of those once a year guys .

No, me either. I've done mine once in 10 years.

The problem is that unless one has xray vision, one cannot tell if there are "other" issues.

I switched to wet brgs. in 2013 when I did the discs. I reused my fine Chinese brgs and installed new $4 Chinese oil seals. I cleaned them for the first time this spring, at 6 1/2 years, new oil in the hubs and greased the caliper pins. The rotors still have the phonograph machine grooves and no problems with any of the Chinese products or seal leaks, whatsoever. And you guys would have stroke if I said how fast I go from Co./Phx. and back! I'll take good maintenance over point of parts origin, any day! Craig

Its been 18 months since I packed my cheap Chinese bearings, the originals on my 2008 Montana, since been sold about three months ago. Those bearing being over 11 years when I last packed them, and many thousands of miles, looked great . IMO its not the bearings or they ALL would look like yours., its no miracle how they lasted its how they are taken care of, set up right etc etc. You can ruin any bearing if things are not right ,it seems these fifth wheels come out of alignment, not packed right to start etc etc. I have had many original China bearings with no issues. Boat trailers ,travel trailers ,fifth wheels , and utility, and RV trailers .

I disagree everything out of China is junk, its what it is in this world we live in. Timken farms out their bearings to China, we seemed to be getting fooled thinking we are getting US bearings.

Second look at yours looks like a typical grease problem, probably never packed right to start .

Just so you know, I posted the above photo to show the uncaring work done by folks in a certain country. That line on the rollers was caused by the inner race having a ridge caused by a broken down grinding wheel. The operator of that machine did not care about quality, and possibly has no clue what quality is. That bearing turned the grease into a silver gray sludge after just one long trip. I replaced all bearings with MADE IN USA Timkens, I'm done with bearings from a country with no moral compass.

Ah, so you pulled the bearing apart before you ever traveled and found that the inner race was bad. That would be the only way you could determine that the race was bad from the factory. Yes, it could have been caused by what you described, or it could have been caused by something else. Unless you saw it new and unused, it's just speculation.

The remaining ridge is still quite visible and I am showing the remaining height. I have been in the tool & die business for more than half a century and understand how things are made. If you cannot or will not accept what I have presented, fine. I still have a customer that his entire business is bearing failure, preventive maintenance and lubrication analysis, he is in total agreement with my conclusion. Perhaps you have more expertise than the both of us.
