Joint Grease in the Wheel Bearing Hub

Nope didn't say that anywhere in my statement. You state that im lazy. If lazy is the same as wisdom from many years of experience then guilty of it. We will have to agree to disagree on grease packed hub over oil bath hubs. All I know is I have had both and packed grease hubs give me less failure and longer life than oil bath.

 

someone better call timken and warn them about dangerous wheel bearing grease.

Personally, I do not like grease in hubs. My logic is that you can easily drain the hub oil at regular intervals and visually see if there is any metal or contamination in the oil. Plus its a 5 minute job to refill the hubs with clean, fresh oil. The grease keeps all the wear particles from the bearings suspended in it and they can't be removed unless everything gets pulled apart and repacked. I just like the ease of service and convienience of oil bath wheel bearings.

 

What's up with all the hating on grease! Theres no need to top the bath like you guys are saying if theres no leak on oil caps.

If you need to fill that cap you have a blown seal of some sort of leak somewhere. You are going to have to open it some way or another.

Grease caps, no traces of grease on the seal? Fine, keep on moving. And if grease starts leaking you have somekind of overheating going somewhere. If you open a grease cap after a 300 miles stretch its still going to be in solid form.

And about bearings... you dont have to take the whole thing apart, just take the cap out, whipe extra grease and its easy to see any kind of shards. Once done, put a new gasket and voila.

 

Yah but If your bearings start shedding debris they need to be replaced, not re-oiled,and neither oil nor grease hubs give any better warning is that happening.

 

All bearings will wear and will put small metal particles into the oil or grease. Metal particles accelerate wear. Its just the nature of moving parts. That's why I prefer oil because its easy enough to just drain and refill.

 

Those hubcaps are cheap and very easy to replace. The minute mine start looking a little bit milky, I change them out.
