A seal is designed to keep stuff in or keep stuff out. On some equipment you use one seal to keep water out and another to keep oil in the engine and on the bearing.

I don't worry about refilling them as long as the spring loaded disc is centered in the Buddy:

Empty the spring pushes the disc toward the axle. As you install grease the disc pushes against the spring and moves toward you. The spring loading of the disc is what keeps the water out. When you see the disc back against the inner stop it means that the grease has migrated inside the hub and you need to add more. Keep track of it till it quits moving in and your hub will be packed.

Too much grease, aka running the disc all the way out to the stop and continuing to pump grease in can push your inner seal out if the hub is full. That's why I only fill half way on the disc movement.


There is supposed to be a relief hole on the side of the housing. Once the disc moves past it (just before it bottoms out), grease just runs out of the hole instead of blowing out the seals. That is until the hole gets plugged with crap and dried up grease.


That may have been a later add-on. Do not remember such and I've had several sets on different trailers and had them apart for cleaning. But yea-verily. If they put it in and it works great. My Ferris ZT has such a relief hole in the spindles.

I think they're better than nothing, but not as good as easy lube spindles, which have the zerk on the spindle, not the cap.


BBs are for the guy/gal that doesn't have the "wet spindle" and has to make do otherwise. No question about which is better. Forrest Wood's Rangertrail trailers to support his Ranger boats has one of the best axles I have seen.

Texasmark hit it on the head. They are designed to boat trailers. Sticking hot bearings in cold water does play some he!! on wheel bearings. I’m an overgreaser as well but I’m in recovery lol. With the buddies, I grease until the plate starts to move outward then stop. I usually put 3 full pumps in each side before long trips. I have not had an issue with electric trailer brakes on my trailers. I have buddies on my camper and stock trailer. I have been pleased with them. They are expensive but do save the time it takes to manually grease the wheel bearings which is worth it to me. But I also haven’t put significant miles on either trailer.
