EZ Loader Trailer Hubs
 

I recently purchased a used boat on a 2000 EZ Loader single axel trailer.
When I went to repack the wheel bearings I found that it had a grease
fitting in the end of the spindle with an outlet in the center of the
spindle. I had assumed it had bearing buddies when I bought it. There was
a membrane over the inner portion of the end of the dust cap. It appeared
to have been solid originally, i.e. no access to the grease fitting without
removing the dust cap, but the previous owner probably punctured a hole in
it to gain access. However, if my assumptions are correct what is the
purpose for the membrane? When I broke the hub down it was full of water
with very little grease and very rough bearings. The paint seal over the
dust cap had never been broken so the bearing had never been repacked. I
bought the boat from an individual through a dealership. At my request the
salesman pumped some grease into the fittings before I left. If he had not
I would have probably have lost a wheel on the way home. Question for
anybody who has experience with this type system: How good is this system
at keeping water out of the bearings if kept greased? How should I maintain
it? Thanks in advance for any info you can provide.

That sounds like it is a Spindle Lube spindle.

It is designed so that you can remove all the old grease by pumping in new
grease, just like a ball joint, etc. New grease goes in, old grease goes out.
I have never used these, but I assume that the design requires more greasing
than bearing buddy systems.

The rubber plug was solid at one time. The owner probably poked it out so he
could grease the bearings without taking off the dust cap.

I would suspect that either the seals were bad or the previous owner did not
grease often and water seeping in through the outlet hole ruined the grease.
Just a guess.

This looks like the one I have.

I agree - but what is the purpose of the rubber plug?

The seals appeared to be good. I suspect he did not grease often and
that water seeped in through the holes in the rubberr plug.

The purpose of the rubber plug is so you can get a grease gun on the fitting.
You pull the plug out, stick the grease gun on the fitting and pump in new
grease as the old grease is forced out the hole where the plug was. When clean
grease starts coming out, then all the old grease has been flushed out. If your
plugs are split or torn, then you need to replace them to keep water out and to
prevent grease from slinging all over your wheels when you go down the road.
