For those that feel you MUST inspect and repack bearings every year, IF that is true, then how can it be possible that the SAME manufacturer would offer a "Nev-R-Lube" bearing. How is it "sealed"?, why doesnt it "pit"? Why doesnt the even-smaller amount of grease "wear out" quicker than the axles with grease cavities??? I'm not going to put-on here, but Dexter (and others) really confuse people to their "must clean/inspect/repack every year 'REGARDLESS' of the miles"- including me!!???

Ahh... its a VERY different design. Thats rather like comparing the basic / standard trailer spindle/bearings with the bearings on cars and trucks.. apples and oranges.

Pioneer village is a great place to visit.
No telling when there might be another rally since we recently lost our talented friend and host Ron Walker to traffic accident.
Not sure if Linda would want to pursue another rally without being able to share the task with her loving Husband now lost.

Not really apples and oranges...
Most newer vehicles are front or all wheel drive and no longer use conventional wheel bearings on their front axles as was common just a few years ago.
However conventional rear drive vehicles such as two wheel drive light trucks and cars such as the crown victoria used bearings virtually indistinguishable in design from those used on a standard 3500 pound trailer axle.
My Ranger has such bearings and they get repacked when ever the brakes are serviced and otherwise ignored. The fact is that these conventional bearings tend to outlast the sealed hubs which are supplied with many light truck four wheel drive applications.

Below is a bearing from a 2WD Ford Ranger and a Dexter 3500# axle...
Which is which?

Ask yourself this: How often do you worry about the wheel bearings on your tow vehicle?

As such using the frequency of bearing greasing on my tow as a standard for servicing my trailer might not be prudent. Just a thought.

I have to giggle at this.

Each and EVERY time the discussion on maintaining trailer wheel bearings come up the "how often do you service your cars wheel bearings?" question is asked. Justification for some as to why they do not bother to service their trailer bearings on a regular bases?

It has been pointed out many times that a vehicles wheel bearings can and do fail but are not designed to be serviced yearly or after x so many miles. But if you have your vehicle serviced regularly the shop will no doubt put the vehicle up in the air and do some wheel inspections looking for signs of a bearing issue. The need for a replacement of a vehicle wheel bearing as I have found out on low milage vehicles can and do happen and it is a VERY pricey undertaking.

Trailer bearings on the other hand are pretty easy to visually inspect, maintain and cheap to replace.

Anyone who has had a trailer break down that requires a tow knows all to well thats not as simple an undertaking as it is to simple call a tow truck to tow your vehicle into a shop. Anything that can be done to possible avoid getting into that situation, is a good thing in my books.

Thanks Floyd you have made my point. The bearings themselves may be the same but as you rightly point out many newer vehicles - front wheel drives, all wheel drives, 4 wheel drives have sealed hubs. Making what you do with your old Ford Ranger - checking them - impossible.

.
I for one think it is a valid question and my bearings are well maintained. The issue of inspection goes beyond searching for damage, it should also provide information as to when the next repack should be... too seldom can result in premature wear of course, but too often can result in wasted effort or expenditure, like uprooting your radishes every few days to see how they are growing.

Another problem from too often is human error such as too tight or too loose on the preload. Like throwing away a good tire using the "Logan's Run" method of tire maintenance and finding an increase in the possibility of get a new tire with a defect.
I still maintain that following standard procedure is a good place to start
but learning why by paying attention and developing good judgement can be even better.
Ritual has its place, but so has reason and understanding.

Not really, but as I said earlier, I don't disassemble my Ranger just to check them.

No it's not a "VERY" different design or "apples/oranges". They're two "tapered roller bearings" facing inward to each other. On the trailers they're further apart but the "Nev-r-Lube" is basically the same bearing design/arrangement in one compact design. I still want to know WHY they should be maintained differently? AND, to which, I'd like to hear it from the BEARING manufacturer and not from the axle manufacturer....

It's all good! We like to get into some "Ford/Chevy" debates every now and then. I actually learn from it! It appears we can do it more on this site without somebody going "ballistic"! In reality, this is ONE hot topic! Did someone mention "generators"?
