What causes a Bearing Buddy to fall out / off of the trailer hub??

FYI. Tandem axle supporting a 20' OR.

The same thing happened about 8 weeks ago. At that time I thought it was a hub issue, with the bearings going bad. Subsequently I spun the wheel and erred on the side of prevention and replaced the existing bearings, etc and re-greased..

Well, after a 2 hour trip this weekend, the Bearing Buddy again fell off. Thoughts???

SeaHag,

I just replaced my old Bearing Buddy's with new ones. My old ones did not fall off but they were getting old.

I have taken my old ones off from time to time to replace the bearings and so forth. They were relatively easy to get off with a Rubber Mallet. They were also relatively easy to knock back on with a Rubber Mallet.

The new ones I purchased were not so easy to get back on. It was a really "tight" fit. It seems the older ones do have a tendency to get a little "smaller" after you take them in and out qutie a few times.

Did you replace the ones that fell out with new ones? If the new ones were not tight then your hubs may be slightly enlarged.

Good Luck

If the bearings are too loose (even slightly) there will be enough wheel wobble to slowly make the bearing buddy fall off. I suppose that if the races were not seated parallel to the direction of travel then the same thing would happen. Maybe even a slightly bent axel.

I would look at it as an early warning of something not right. Something is causing the round opening to be effectively oblong (with wobble)for a millisecond every revolution causing the round bearing buddy to be forced out.

Did it happen on the same side both times?

Try putting some marks on inside of hub where buddy bearing fits up to hub.Use a center punch to make punch marks on hub and than reinstall buddy bearing cap.

yes, I replaced the one that fell out with new. I'm on your same line of thought with the hub being slightly enlarged.

dburton,

yes. front right(starboard) both times.

On another line, what happens if I were to leave the Bearing Buddy off, installing a dust cap? I guess I have grown so accustom to Bearing Buddies it strikes me as odd not having them. I probably will try dauntless18's method for the 3rd 'go-around'.

Thanks for the input.

I have no idea why the above post went in a second time.
3 hours after posting the first post, I hit the Back Button on my Browser Window and it posted it again...
Maybe next time I will hit "ANY KEY"... with a big hammer.... :-))

good trick for getting new
bearing buddys on. They are often big to get on the hub if you put them in the freazer for a day. they will get smaller and then once they are on there they will get big and make a nice tight seal.
