HUB OIL: levels etc.

Engine oil would be better than nothing, but I don't think it will do the job very well for very long. Just get a bottle of hub oil and carry it with you, that way you're prepared. The tip about comparing the heat of the hubs by feeling them is a good one too. You can do the same thing with brake drums to tell if the brakes are working equally, just be careful, drums can be HOT!

 

when I first bought my truck, looking at it one day, I saw a small slit in the rubber hub plug. I THREW IT AWAY! I thought this is defective. it has a cut in it & put new one on. later that day I found out that the slit or pinhole was there to releive pressure. went back into the garbage can & got back my plug.

 

I realize this is a bit old, but here's another tip: if the window where you check the oil is too dirty to read, carefully pop the rubber stopper out and wipe the inside of the window with a clean rag. Helps to have a rubber glove as it's a bit messy. If the stopper still has some flexibility to it, use a bit of the oil to lube the inside edge and carefully pop it back in. If it's too stiff and you try and force it, the window could break. Helps also to have a replacement stopper handy.

 

What is the difference between grease hubs and oil hubs. Operating temperature and is the inner wheel seal any different. Can grease hubs be converted to oil hubs. How.

 

Hubs getting over heated can also warp aluminum wheels if they get hot enough. It tends to warp the lip away that's opposite the face and push the lip down. Which the bead will just blow over the bead seat and bye bye tire.

 

Never remove your wheel/hub assembly then. You would #### if you saw the little clip that holds the whole thing in place.

 

Keep in mind that when you add oil to a hub steering / trailer, you need to allow time for the oil to ooze / flow through the outer bearing and into the center of the hub. Don't just fill to the line and stick the plug back in.

 

I don't believe anything is different. Thoroughly clean all of the grease out add oil and good to go.

 

no need to worry about putting engine oil in there gear oil is widly available in fact you should carry some with you. if you have a hub that's low. unless they did service to it and never filled it all the way back up you have a leaking wheel seal.

drivers responsibility to check hub oils and add if needed just like engine oil. if your loosing oil from a hub you have a wheel seal leaking and need to write it up as such and keep it full
