    Default Bearing buddies: yes or no ?

    My trailer has brakes, and I mistakenly over filled my b/b's, result was grease sokes brakes. My fault yes, but it leads me to the question, do you really need them ? If your equipment is in good shape, I'm not sure how necessary they really are ?

    I think about all those 60's n 70's cars running around w/o b/b's, on the same greased bearing set-up on most trailers. They seem to last for years n years w/o any troubles. I know they aren't dunked under water rutinely, but most saw lots of water over the years and cintinue to function. Just looking for opinions, thanks !!!

    I run them on both trailers, I like them, some like the oil filled hubs, I personally don't like the oil baths.

    The newer style BB are nice because they have the blue indicator ring with a small chrome cap that goes over the blue ring to cover them instead of the rubber boot that I know that I have lost so many of those over the years. I'm sure I'm not the only one.

    Chris,
    the main reason to run bb's is so when you back your hot/warm hubs into the cold water, the bb's will fill the void/vacuum in the hub so it doesn't suck in H2O.

    i run them, i love them, i think there a must. here is a pic for you. pulling the trailer to the lake for an hour you back the trailer in to the water and the warm wheel hubs now are cooling very fast in the cool lake possible creating a vacuum. wheel seals are designed to keep grease in, not water out so the vacuum now pulls water in to the wheel bearing...... you know the rest of the pic. bearing buddys are designed to keep a little pressure on the seals so that the hub never gets to a vacuum. you do need to be careful greasing the hubs you want the piston in them to be centered not bottomed out in either direction.
    widowmaker: you know people that are running the oil baths? why dont they or you like them? did they build the build it them selfs or what kit did they use? i was thinking of going to them. it seemed to make life easer. the idea of just popping off the cap draining the oil out and re filling with out getting all greasy. just was out with brake clean, blow dry and refill. sounds so good
    oops 2 min to late i guess i deserve that from the long winded story

    Put simply and repeating other posts, you only grease a Bearing Buddy enough to move the inner cup, no more, as the grease heats and expands it will put additional pressure on the spring and allow for expansion...

    They are a must IMHO.....

    X 3 positive displacement, spring pressure keeps the water out. only need enough grease to lift the piston off the stop, the spring does the rest.

    My trailer has B/B's, I was just considering other options. Do you guys fill the bearing cavity all the way, or do you leave room inside ? I believe my mistake was to completely fill the bearing cavity along with over pressurizing the B/B.

    I just don't want to grease down my binders again. Thanks for the input all !!!

    no i dont fill the cavities just check them frequently for spring pressure. other options is the oil bath. the Aussies looked like they had a good unit

    No. Just for the reason you stated, and a few others. Use a good waterproof grease and pack your bearings every two years.

    very cool products, unfortunately about double the price compared to bearing buddies, after the exchange rate not to mention the shipping.....

    55 AUD for a set of two.... ouch. that's about 48 dollars in US... for a 1.980 hub

    there cool to but i didn't like the blue it clashes with my color, also the blue may not let you see the water in the oil (the reason why i wanted them). and there is another called turbo lube
