FOLLOW UP - Wheel bearings why oil is better than grease!

The time has come to open up my wheel bearing and see how they have gone with using oil in them and NOT grease! If you have not seen the original video here is the link:

I agree, I used stp oil treatment on my motorcycle wheel bearings

[shanecollins]

Classis Range rovers had oil bath rear wheel bearings. Also the front bearings and cv joint were in oil too.

Just changed an axle seal and the bearing is submersed in gear oil.I wasn't sure if it would even hold onto the grease, so THANKS for answering my question...Have a DANDY !

Two piece seals like that are the gold standard for industrial and commercial grade equipment it takes the seal wear surface and makes it the serviceable part of seal instead of having a motor or axle shaft or housing with a wear groove that requires a fix before it can sealed. Grease will dry out and become a paste inside sealed cavities. Wet bearing housings do not suffer from this. Wet housings need to be inspected but the same applies to greased housings. I have several trailers In my business and my failures stopped when I changed to wet hubs. The needed periodic brake check or tire replacement gets the oil level checked more than often enough.

I think most if not all Semis run oil bath instead of grease. Got a sight glass on each hub to check the level too.
Oil is superior as long as it is changed regularly and kept at the right level.

Just converted a Flatbed Gooseneck 10K Axels from grease to Oil bath. Thank you for the information and the video.

[jackfourbee]

Definitely doing the conversion.
Got my seal of approval 😁
you might have to speak to graham about a handbrake upgrade for the old girls.
Keep up the good work Matt.

[dannysteel]

Makes sense to me. But if you're going to do it this way, (oil instead of grease) why not have your supplier build you a "sight glass" style hub, like on semi trucks and trailers. Then you could easily drain the old oil out periodically, and put new oil in.

How long do you run your bearings Matt?
Interesting topic, considering Grease is Oil with a suspension additive (thickener)

[rsemrad]

Matt,
Are you still running two piece seals? How are they performing? Have you experienced any issue with water/dirt egress into the labyrinth? 3:40
Thanks

[heywoodjabozoff]

could you do that on an alternator bearing?

[wobblyplanks]

@1:57, "exposed to probably a bit of oil and water"? I would certainly hope they were exposed to a bit of oil lol.

[sallymoore]

I wonder what Allan Gray would say about this hmmm 🤔

[miguelangelvalderrama]

Both oil and grease are not good lubricant for bearings if they are not EXTREME PRESSURE lubricant, without that friction can wear out ANY bearing🙄🙄🙄🙄

[walnutslipnot]

So why do manufacturers make CV joints and universal joint in grease? The parts see the even amounts of load if not more?? This is an argument that’s older than hide and go seek.

[michaelau]

I've always thought oil would be better than grease but this video doesn't really prove much either way. Why? because the bearings were dry as chips, the hub was dry, etc etc etc. You had already pulled it down and cleaned it all off. As a mechanic and a teacher (of Automotive) I'd appreciate it if you would do a valid test and actually drive the vehicle and then strip it down and show us that happening in the video. Call me a cynic but I've always been suspicious of videos etc that have things already prepared. Its a bit like the old cooking shows where they say "and here's one I prepared earlier", it really doesn't teach or prove anything except that the person expects people watching to believe their word as though it is gospel. Your new winching videos are great but this one needs to be redone to prove your point.
