I just like the idea of getting all the old grease out. Pumping on the fitting seems to just push a ribbon of fresh grease through all the old stuff.
I agree IF you are not going to use the Easy-Lube function. If this is the way you are going to lube the bearings, you might want to use plugs instead of the Zerk so there will be no mistake.

Dexter does recommend a 12,000 mile/yearly bearing inspection so - what's the use of Easy Lubes unless you just like to grease things up

Yeah, if I owned an easy lube equipped rig, I'd probably pull the zirk fittings and use a normal axle cap...

Reguarding the removal of old grease from wheel bearings I use MEK which can be found any place paint is sold. Pour enough into a coffe can to cover bearing(s) and replace can lid. swirl the can in a circular motion and the grease will disolve out of the bearing. Note that MEK evaporates quickly so keep can closed when not using. Also wear protective gloves to protect hands. Lay clean bearings out to dry before relubing. have used this method for years without damage to bearings. Do not get on painted surfaces.

That's an interesting idea. I'd suggest avoiding using gasoline just because of its low flash point (like -45f). I usually use kerosene or diesel (100f and 143f) but have to blow them dry with a compressor (don't let the bearing spin while blowing it out).

Anyway Methyl Ethyl Ketone flash point is like 25f, which I would think would be a good spot for a solvent for safety and fast drying.

I use one of those black or green coated canning boilers. It fits parts bigger than wheel bearings that I clean sometimes, and it is metal and has a lid (in case of fire). Being a dark color, if I have something really grimy I'll leave it out in the sun with the lid on and let it get warm and soak.

I will check them out down in florida to check for wear and tear on the brakes. should be ok as the dealer said there are brand new
Greasing a 12k miles or 12 month still required for easy lube. Here is company statement.

The EZ Lube bearing system was designed for two things. One was to allow
boat trailer owners a way to add some grease after immersion in water and
the other for other trailer owners to add grease without tearing everything
down in between the required yearly inspection and repack. I was service
manager for Dexter before the EZ Lube was developed and what I found is that
most trailer owners do not perform the required axle maintenance. By having
EZ Lube the owner now has a way to get grease to the bearings that he
normally would let go dry. The EZ Lube has helped many owners avoid bearing
failures by giving them an easy way to add grease. Should they still
teardown the axle and inspect and re-grease the bearings-absolutely. We
recommend this in our service manual. Will every owner do this? 26 years in
the business tells me that most won't. I have attached the section from our
service manual that addresses EZ Lube and our maintenance schedule.

I worked several years in a plant that used MEK. Ours was a mixture with Acetone. Because of the flamability, whe were required to use safety cans for transport and use. Please be very careful when using MEK as a solvent. I would never let MEK sit outside in the sun to warm up. Just my HO,.

I have always repacked, inspected, replaced and repacked my brakes/wheel bearings myself until the last few years. At age 75, down is farther and up is getting worse every year. Not only that the wheel and tire assembly was getting heaver. Just like my old Navy uniform has shrunk while hanging in the closet.
I found a local utility/farm trailer manufacture (not a RV dealer) that I trust and now I have them go over my brakes every year. They are more expensive than doing it myself however, I find that it is MUCH easier on the body.
May you have following seas and fair winds!

Richard- being of the same age I know what you are saying and feeling. I still do my 5er every year (triple axle) and my flat bed (tandem axles w/duals). Been considering a hyd lift dolly for under the wheels for R and R. For general info when relacing the wheels don't forget to properly torque the bearings preload
