Default How to install bearing buddies??

Can anybody explain how to do the installation of bearing buddies? What grease would you use with them?

Thanks

Fill the inside with grease, hammer onto hubs using a piece of wood between the hub and hammer..... they make grease specifically for boat trailers, at boaterworld and west marine....Mick

So the bearing buddies are basically a "cap" that fits over the hub? I thought a total disassembly of the bearings, races etc... would be required......................thanks

I concur. Light taps to the wood piece is all required once it's correctly aligned. Put in enough grease to see the plunger move out.... thena few more but don't over fill it. If you do, when you roll down the highway the excess will sling out all over your tires. I'd also suggest putting the bearing buddy bra to keep it all clean.

Be careful... some axles will not work with bearing buddy's. If you have the popular eliminator axles with fittings that lube the inside bearing first, buddy's will not work.

Hmmmmm, How do I tell what I have. Right now I can remove a rubber "flap" from both hubs and there is a zerk fitting right in the middle of the hub. What do i have and what do I do to go the bearing buddies route?? They just seem better than what I have now.

What you have is a spindle lube system. Remove the rubber cover and a grease zerk is threaded in the spindle. There is a hole drilled though the spindle and another hole is drilled 90 degrees behind the inner bearing. The idea here is to pump grease via the grease zerk. The grease flows through and out of the spindle through the inner bearing and the outer bearing returning to the bearing cap. Your bearings are full when you see grease returning and flowing around the spindle where you are pumping. These type systems are 100% better than bearing buddies. Do not use bearing buddies in this type of system. YOU DO NOT NEED THEM!

Sounds like the axles that HeadHunt'er is talking about. Without seeing it, I can only guess that they are. Sorry, BB's won't work in your case. Best to check with your local dealer to confirm though. I've been using BB's on all of my trailers since back in the early 80's.

Also, if you over-fill them you can blow out the rear seal. Don't ask me how I know...It was from back in my younger days...And yes, always use the bra's with the BB's.

All they are is a bearing cap that are spring laoded. What happens is you fill the cavity with grease thru the zerk fitting, the spring tension keeps the grease under a higher pressure than that of the outside water pressure hence no water intrusion into the bearing cavity. The problem with this system is the rear grease seals need to be in very good condition, and you cannot over pump the grease or you will blow out the rear grease seals. So once you have the cavity full, evey so often give one or two pumps on the grease pump, no more or the seal will be shot!

To install remove the old bearing cap, and replace with the new replacement bearing buddy cap. I use a piece of wood and drive them on with a hammer with the wood in between. The key is getting them on evenly.

I prefer to use the SS caps with the blue insert. The blue insert will allow you to visually see if grease needs to be added.

They are actually called trailer buddy products:

All STOP. DO NOT install Bearing Buddies. You already have Posi Lube spindles on the trailer and they are a MUCH better system than any Bearing Buddies.

Take the Bearing Buddies back to the store and get your money back or throw them in the trash.

You need to be educated in the diffrent system's. You can repack the bearing's without taking the Posi Lube system apart. No damage will happen. Just keep pumping grease into the zerk fitting on the end of the spindle after you remove the rubber cap. Place a throw away Dixie cup under the end of the spindle to catch the old grease.

Do not do this with Bearing Buddies. You will blow the seal.

If you find that a seal is ever leaking. Replace it with a double or triple lip seal of the correct size. Some of the box auto part's store's do not carry double or triple seal's. Auto Zone come's to mind.

Posi Lube spindles.

This is the best system of lubricating boat trailer axle that there is. Get the maintenance instructions from your dealer or the manufacturer and follow them. This is a system that also allows you to completely replace the bearing grease without taking everything apart.

You cannot install "Bearing Buddies" on these axles and you shouldn't try to.

This link may not be your exact system, but it's close.

This information is greatly appreciated guys, thank you. I will keep my current set-up now that I know it is the better way to go. It just did not seem as "water proof" as the bearing buddy system. One of my rubber flaps does have a crack in it so I will have to have that replaced, but thanks again!!!!!!!

GOo with posi-lube. Bearing buddies went out in the late 90's.

The color doesn't matter, different brands are different colors.. It should be marine grade, high temperature wheel bearing grease. Read the packaging.

Nope. Re-read the above posts.

Just be aware that you should pick one grease and stick with that grease. Don't mix them.
If you mix them one can help break the other down.

With the Posi-Lube spindles [That's what you have imanutskie] you can totally repack the whole hub and bearing's with a grease gun and enough grease. The new grease will push the old grease out thru the hole in the hub cap where the rubber plug goes. That's why I suggest using a 16oz Dixie cup with a piece of cardboard below it to catch the old stuff being pushed out.
