When Using Bearing Buddy Bearing Protectors Do I Need To Repack Bearings Periodically?

Updated 07/17/2024 | Published 09/12/2017

Question:

Does having a Bearing Buddy installed negate the need to take apart the wheel hub and repack the bearings with fresh grease periodically?

When you use the Bearing Buddy Bearing Protectors like # BB2441, so you do not need to take apart the wheel hub and repack the bearings. The Bearing Buddy Protectors have a spring loaded seal that keeps the moisture and debris out of the bearings. This pressurized grease will maintain bearing function as long as the seal on the hub stays functional. If this seal is broken, I recommend inspecting and repacking good bearings when you replace the seal. As you maintain the grease in the Bearing Buddy, it continues to fill the bore, so your bearings and spindle stay properly lubricated for proper function.

How often do I need to grease bearing buddys?

We recommend greasing your hubs on your trailer about every 12,000 miles under normal conditions. If you are hauling heavy loads often then you may want to so it sooner.

Thank you!What I mean is how often should I shoot grease into the bearing buddy as a preventative maintenance function?After so many trips,once a month etc.

Assuming the seal is in good condition (grease isn't escaping) there really shouldn't be a need to add more grease throughout the year. You're safe to follow the general guideline of once a year or 12,000 miles.

Can you use Bearing Buddies on a boat trailer with drum brakes? Thanks, RB

@RickB Yes, Bearing Buddy bearing protectors can be used on a boat trailer with drum brakes. I do recommend using their matching grease seal kit as it is capable of the higher grease pressures you get with a Bearing Buddy. This helps prevent grease from getting into the brake assembly.

@BudM I just had my wheel bearings replaced on my single axle boat trailer and Bearing Buddies installed. The tech recommended that I add grease every time before I put it in the water after any trip of decent distance. Don't I run the risk of blowing out a rear seal doing this? If the seals are good, where is all the original grease going to make room for more? We probably tow it enough to get the bearing warm 5 or 6 times a year, and in 15 years of boating, I've never seen anyone else doing it. Is he being too cautious? Am I being to reckless not doing it? Thanks, ST

@SteveT If you used the auto check style bearing buddies you can simply check the pressure cap to determine when you need to add more grease. Typically I recommend checking them a few times a year depending on use. As grease doesn't just disappear you would notice if it were come out of the hub.
