another bearing buddy question

[Roop-Dogg]

i aquired a trailer that has bearing buddys on it. i want to take them off so i can inspect/replace the bearings. however, i can't get them loose. i've tried to wiggle them loose with a larger slip-type plier and i've tried to loosen them by tapping them from side to side. no luck. maybe i'm not being aggresive enough but i didn't want to damage the hub. any help appreciated.

try spraying with wd40 it may help ?

I jack up the trailer and use either a dead blow hammer or a regular hammer with a 2x2 and hit it on the side while rotating the wheel. It takes a few hits before it starts coming out, but once it starts it comes fairly quickly.

They can stand a pretty good blow as long as you have a piece of wood to cushion the blow.

Like any bearing cover you sometimes have to really hit them. I use a rubber malet. Sometimes you can get a flathead screwdriver in the seam to get them started.

The bearing buddy site recommends using a wood block against the bearing buddy and hitting it with a hammer, rotating between hits. They are in there tight - they have to be to work. Don't hit directly with a hammer or use pliars on them, if you damage/bend/dent the outer housing they are trash, the piston has to be able to move inside.
