I have Dexter 6000# ezlube axles on my trailer and there is always a coat of grease on my chrome wheels that makes them look dirty. This seems to happen when the trailer sits, not when in use.


I figured out that the interface between grease cap that is pressed into the hub housing leaks liquid from the grease. It is a runny liquid where the grease is thick like you would expect.


Is there a way I can stop this leaking? Here are a few ideas I am considering:


--Replace grease with disk brake bearing grease--hope it doesn't release the liquid


--pull the grease caps and reinstall with teflon tape at the interface--not sure if the grease will break it down


--there is quite a layer of grease sitting in the grease cap. Not sure if it is normal to have this much grease or not. Could remove this 'excess' grease as it is not in the bearings.

Teflon tape would not be affected by grease. You might install some "Bearing Buddies". These are caps with a good tight fit and a grease fitting on the cap and a spring reservor and hold extra grease under pressure. Part of your problem is that the hub pressurizes as it heats up due to expandsion and the grease weeps out. I used bearing buddies for years on boat and horse trailers with no leakage problems.

I have EZ lube dexters, no leak what so ever. If you fluid is thin enough to run or drip, then it is not really grease anymore.


Jack up one side, pull the plastic cap off, hook up grease gun to zerk in center, spin wheel, pump grease, wipe off, pump grease, wipe off, spin wheel, pump grease, wipe off. Do this untill nice clean grease oozes out of the front of your hub. This should replace all of your old runny grease with new fresh stiff grease. Wipe off excess, reinstall plastic cap and off you go.


If you still have leaks, you might have other problems. Grab the tire and rock it back and forth, there should be about 1/8" play or bearing clearance.


Hope this helps.


ON EDIT: As soon as you remove plastic cap, you will see grease every where, this is normal. This is a messy procedure that requires alot of cleaning rags and a full tube of grease. You wheel replace about 1 cup of grease on each side.


Neat thing is, no bearing removal what so ever. You put the grease in through the zerk, grease go's in from the front and works all the way to the back , turns the corner and comes straight back out at you. Full grease job, with only a grease gun and wiping rags. Not to bad, once every 12k.Edited by: Bronco
