Grease in trailer axle bearings instead of gear oil?

The grease works as a lubricant, yes....

However, once the bearings in the hubs gets up to operating temperature, the grease will solidify. Thus, making it a liquid with the consistency close to gear/hub oil.

So basically it's not gonna solve your problem. Prolly best to get a spindle sleeve or a stemco style seal that incorporates a wear sleeve that fits onto the seal area of the spindle.

Good luck

 

I've never tried that, so I couldn't say.

Thing is, those hubs are gonna build pressure no matter what you do. Even though the cap is vented, the pressure is gonna take the path of least resistance. I would think it would push the grease out no matter what. Also, grease that thick would be a nightmare in the winter if you live in cold temps.

 

By manufacturer grease is semi liquid to flow around bearing rollers to grease and cool. If grease do not liquify the bearing will get hot and destroyed. Maine cause of hub fire btw if you ask me. And spindle will be destroyed too. Cheaper to do proper repair with sleeve.

 

Try STEMCO Voyager seal it will help

 

Could use axel surgeon.

 

Try this product. I used it for years with no issues.

Stemco Guardian is made just for this reason. If your spindle is extremely pitted, a little high temp silicone between the spindle and the steel liner should solve the problem.

 

The zerk ( grease fittings ) on your axles are actually pressure relief fittings. If you or someone has changed those fitting to regular's, you have to be REAL carefull how you grease those, or you will forever have the problem.
