Wheel Bearings/Bearing Buddies

I lost a bearing buddy bra on the road last weekend. Here is my question.

Since I have not touched the wheel bearings in 9 years and I'm not sure when the original owner conducted maintenance on the wheels, should I do maintenance or just make sure the bearing buddy is full of grease? I was going to spin the wheel to make sure the bearings are not making noise. I'm sure there is at least 20k miles on the trailer.

The trailer is 18 yrs old.

Thanks for any advice.

If it's that old, it's due for a service. I am going to do mine as well in the next few weeks. The bearings are probably $20 and then some grease. I would hate the idea that the a bearing would fail and then who knows what happens.....

pull the bearing buddies
pull the bearings - replace loading properly with fresh marine grease!
pull the races - replace!
re-install bearing buddies - pump full of grease.
Buy new bearing buddy bras and put on.

If your old bearings are "OK" you could soak them overnight in mineral spirits, clean, load with grease and put in a ziploc baggy and keep in vehicle "just in case"!

Nothing good happens, when bearings seize. Bearings are cheaper than, towing, rebuilding hub spindle, replacing axel, mad wife (when week end is ruin),etc.

Bearing buddies are no substitute, for inspection and proper maintenance. (hand packing a wheel bearing)

Yearly inspection, check your brakes, while you're at it.

Second that, time to check the bearings and repack! If the bearings are clean (no rust, pits, damage to races, etc.) just wipe out as much of the old grease as you can, flush clean with some solvent, repack well. I don't see anyone stating the rear seal should be checked or replaced. Rear seal is just as important as the repacking! I did a simple search on boat trailer bearing repack and tons of information out there! I will agree with some of the post - no reason to wait for bearing failure if you can repack for a can of grease $5 and couple hours of time. By the way the bra isn't really as important as the bearing buddy plate (with the grease zerk) being free to move slightly in the cylinder (means there is adequate grease). See the bearing buddy website for more information on that....

Repack every two years and replace all bearings and seals every four years.

Definetly a good idea to just check em. When we just bought our 87 the first thing we did was check the bearings only to find out that there was some old crappy grease in there and it probably wouldn't have made the trip without something going wrong. The problem with the bearing buddies is that people think they can just keep pumpin grease in there and it will all be good. Always a good idea to take them apart once a year especially if you put alot if miles on it. When you repack them make sure you work the grease well into the bearings. The grease is alot cheaper than doing damage to the bearings.

On my last MC, there were bearing buddies on the trailer and they were easy to access. However, on my most recent trailer (2001 model) there is simply a plastic cup over the hub which is held on by the tire/wheel. Do you guys suggest keeping this or should I ditch this glitzy plastic thing and go back to exposed bearing buddies so that I can check the grease levels?

Thanks much!
