How often should I

[Racoon]

add grease to trailer wheel bearings? I go about 80-100miles almost every weekend.

Sure wish some one would give some information on this, I've been putting a couple shoots of grease to mine about every other month but I don't get to put as many miles on mine as you.

Bearing buddies will tell you. Otherwise, I would give it a couple shots every other week or so. Without bearing buddies, you won't know you've greased it too much until you've blown the seal

Do mine once a year. Take it completely apart...clean with carb cleaner....check for pitting and water damage...repack and put back together with new grease.

My Triton trailer says to grease after every use. They must own stock in a grease or seal producer. The "bearing buddy" system on it is different than any other that I have had, though. The front side has a rubber plug that seals the housing. Remove that to access the zirk and the whole thing appears to be an open unit where the excess contaminated grease can flow out the front instead of blowing a seal.

Frequency really depends on your hub setup. If your seals are good so that you are not losing grease, you won't be able to add much without blowing a seal.

What Scrapper said and use the high temp green grease for those hot days.

I check mine bearing buddies every month or so than add as needed

I drive ~100 miles a month and shoot grease into it about 1/month. 3 pumps each hub. I annually take the hub apart and repack it.

I think it's a matter of preventive maintenance. You should add grease when the hubs need it. How do you know if the hubs need grease? Pull the dust cap and look for water intrusion. If you see any telltale signs of water, remove and repack the bearings with grease.

Do not fall for the "add grease when needed" bit. The space inside a hub is limited. Once you add more grease than can occupy the hub, it starts blowing out the inner seal. When that happens, you get water in the hub every time you immerse it in water, and you have to add grease everytime or risk ruining a bearing and axleshaft. And for that reason, bearing buddies do not promote proper maintenance.
