Checking and/or packing a "sealed" bearing.
I don't know how many people know this or not, but it's possible to check (and pack or repack) a sealed bearing. The pillowblock bearing in this example (just happened to have it laying around) happened to be packed pretty well, but many that I have checked have not been. (actually, some horribly so) The only thing needed is a really pointy tool of some sort to carefully remove the seal. I use a dental pick tool end sharpened to a point.
Anyhow, you may never use this info, but I thought that I would share it.

I Just Did That The Other Day To An Axle Bearing On A Ford Focus. I Have Also Used Our Air Powered Grease Gub With The Needle Attachment On It To Peirce Things And Grease Them That Way

just a suggestion though, different grease types, brands or any grease in fact should not be mixed.
To do it properly you have to remove the existing grease, degrease it, clean and dry it and pack it with only one type of grease

I agree with not mixing greases. Below is an excerpt from an aircraft company and service warning from the our Civil Aviation Authority. In fact some aircraft maintenance books now list the exact grease used when any grease is used on an aircraft or helo.
I'd hate to see a pump bearing set seize at speed from imcompatable grease or trailer wheel bearing fail at 55mph on a single axle trailer.. Highly unlikely from the guys on this board. From what I've read they all clean, repack and replace ...
Today, new generation grease-to-grease
incompatibility issues can be real showstoppers.
Grease has become a very complex
lubricant. An increasing number of
bearing failures in helicopters and aeroplanes
have been traced to the breakdown
of the lubricating grease.
Mixing incompatible greases has been
identified as an emerging airworthiness
One aircraft manufacturer, Britten-
Norman, warns in the introduction to
service bulletin (SB) 309: “The intermixing
of grease with a clay-based thickener
and grease with a lithium soapbased
thickener, produces a chemical
reaction that solidifies the grease causing
accelerated wear and possible seizure of
