My three new axles are ready to install. They have the Dexter EZ-Lube spindle and I was wondering if anyone else uses that spindle on their boat trailer? if so can you use a Bearing Buddy with them?

I have these hubs on my 48' enclosed car trailer, nice hubs but I do not think that they are designed to be submersed in water. Doug

They are for use were the axles are immersed in water, that is one of their strong points according to Dexter. I picked these up at the Dexter Factory in Oklahoma today and talked about the Dexter brake system also. I think I will go that route instead of Kodiak. I wont ever have the trailer in salt anyways.

Have them on my trailer that dunks in salt water with no problems. Bearing buddies would be a waste of money. While grease is pumped on the small end of the spindle it will force into the large side and back into the small side of the spindle.

I have them on my trailer (Owens& Sons) for about 5 yrs now and dunk is salt about once a week. IMHO they are way better then bearing buddies because you pump the grease into both bearings rater then just fill the cavity on the outer bearing. You can actually pump loads of grease thru to cycle out the grease if you want. (I still take apart every now and then to inspect and all that)

I think Doug might be thinking of oil-bath hubs, as you would find on medium and HD trucks & trailers.

You can use bearing buddies on the EZ-Lube's but I'd prefer these- http://www.airtighthubs.com/products-sport.php

The object of either is to prevent water from being drawn in when the warm bearing hits the cold water and the internal volume contracts.

Here are instructions specific to using the Airtite with drilled spindles, including pics- http://www.airtighthubs.com/PDF%20fi...nceandOper.pdf

Additionally, the Airtite has a far superior backside seal.

I have them on my trailer, Performance Trailer, and my understanding is that you should not use bearing buddys. The principal of the E-Z lubes is to push the grease thru the center of the spindle, thru the rear/inner bearing, thru the front/outer bearing and out of the assembly. Replacing the old grease with new and pushing the old out. Makes sense that the bearing buddy would screw up/prevent this process. The owner of Performance is a friend and the info is from him, I would think he would be a good source, he uses Dexter E-Z lubes on the trailers he builds. There is some info on these on the Dexter site that shows how they are designed to work.

One way to help keep water from being sucked in is to simply let things, bearings etc, cool down before you launch.

Go to the second link I posted and you'll see how drilled axles work.

They don't push grease out the back, the circulate it from the rear, foward, through the races. BB's will not help or hinder the operation in any way- they simply provide positive pressure inside the hub cavity.

Myco uses the EZ Lube.

Need I say more?

Not sure if you meant BBs or Airtight's system, but EZ-Lube/Posi Lube were designed to do away with Bearing Buddies. Adding A BB would negate the benefit of the EZ Lube design.
