Hi John; Can you explain why grease would make the bearings run hotter?.
added friction trying to rotate the additional pound of grease. kinda like a petroleum butter churn.

that would be my best explanation, i have tried it both ways on my wells and notice the hubs are consistantly hotter when filled to the top with the grease gun.

i agree that in a marine application keeping the air space filled to not allow water in is a good thing, on a travel trailer it seems like a waste because you will be removing the hubs every year or 10K miles to inspect the brakes anyway.


you call them ferrets, i call them weasels.

Too add to the dexter ezlube hubs ,the grease can and will get past the seals and all over the shoes ,magnets and drums .Specifically ,6 new cargo trailers
dual axle dexter in the light and heavy duty axles size ,all had grease expelled
all over the shoes ,drums ,magnets .They had never been serviced until I did
the work for the company that contracts me for their fleet work ,so I know the history of the trailers since new ,further ,all the spindle nuts were quite
loose as new ,probably so they could run cooler ,I recommend manually
checking and greasing all wheel bearings where applicable ,best way to know just exactly what you have going on with your bearings.Pumping grease into
the spindle without really knowing how much or if the bearings are really getting a good grease job is difficult at best ,in this case ,clearly they were over greased when newly assembled.
