bearing buddies
 

I have the grease zerk in the axle, but can i still use bearing buddies over that?

had to tear one down yesterday. Back seal blew out.

does that zert do just the inner bearing or does it do both, if only the inner i would for sure have buddy bearings to grease outter

make sense..............it just does the inner bearing, or that is the only place the grease comes out the axle.

It pushes the grease forward as long as your rear seal is not blown out.

I have the grease zerk in the axle as well. I find that buddy bearings can put pressure on the seal causing it blow. I use the metal caps with the removable rubber. As you pump in new grease, the old grease can be removed out of the metal cap through the hole created by the removable rubber piece.

Bingo. I hate bearing buddies. Most seal and bearing failures are because people think to just pum grease in a buddy and it is good. Those things are notorious for people blowing rear seals out

yea, I can see that. But when you grow up in a mechanics shop (literally) you have an idea the principles behind the Bearing Buddies.

just trying to see if it's an issue to use the buddie over the zert that is already there.
Kinda like wearing a belt and sussuspenders no??

Yeah, you can say that it will double protect.

Thanks brother!

Do the Buddy Bearings get grease to inner bearings?

No, they just keep a minute amount of pressure on the grease to hold it there.
BUT, like stated above , too much pressure will blow the back seal out and grease will sling all over the place.

kinda what I thought
