Bearing buddies ?

For years I have owned several boats....all trailered.... One is near 6000 pounds... All trailers have bearing buddies on them... I have towed the big boat a 1000 miles in one trip....What do you think about putting bearing buddies on a travel trailer? Is there a compelling reason why you shouldn't?

Most boat trailers don't have brakes, so the excess grease that brearing buddies push past the inner seal doesn't contaminate the linings. Brg buddies prime function is to expell water from the brgs, and supply fresh grease before the brgs rust.
Some travel trailer axles have grease fittings , But those are set up to push the grease down the center of the spindle, to the inner bearing,then back through the outer brg. and the excess is wiped off the outer brg, that system doesn't blow any grease past the inner seal , and the fitting is covered by a rubber cap.

Also, travel trailer axles are not submerged like when you launch a boat. You still need to pull the wheels to inspect the brakes and repack bearings at that time.

When i pulled trailers, they were small (Less than 1 ton) trailers and I buddied the bearings, The only issue is I also had to replace the rear seals on the bearings, The OEM"s could not take the constant pressure.

Beyond that.. I only replaced one bearing set in the what, 25 years.. That was the bearing set that was bad when I bought the trailer.. Never replaced one with a buddy on it.

I detest them. People do not know that three pumps is enough, if not too much and use them as an excuse to not pull the hubs. I charge extra just to clean up all the extra mess they make by pumping them full. Not to mention they can RUIN entire back plate assemblies and hubs.

I have them on all of my trailers. You will have to change the Wheel Seal to one with a spring loaded sealing element. It is just a spring used to put additional pressure on the sealing lip. And as mentioned not to over grease them. Easy does it. On mine I can tell when additional grease is needed as the fitting will not move when you press on it. As I grease the wheel the fitting will move out compressing the internal pressure spring and when it stops moving out you quit immediately or risk blowing the grease seal and loading the brake drum with grease. In case you do not know it, grease and brakes do not play togeather very well. Good luck on your choice.
