  Location: Chicago western burbs | I have bearing buddies on my trailer.   How do you determine when they are full?   I would hate to add more grease if it is already where it should be.    How close should the piston be towards the outer ring of the buddy?    Thanks in advance. |

  | all you need to do is push the plate along side of the zerk.  If it gives a bit, you have enough grease...  
  
If you over-grease to the point that grease is coming out the back seal, you'll have problems.    
  
I have always felt that if you pull the hub apart every fall and re-pack with new seals, adding grease to the hub is a moot point.  I have dunked my trailer numerous times, and I still get no water in there for th short time it's in the water..

  | Also be sure you actually have the original "Bearing Buddy".  There are imitations out there that are junk.  These imitations also have a sticker on them similar to the Bearing Buddy decal, but the quality of the product is not the same. |
