Transfer Case Bearing Cleaning

[tgreco]

Just tore down my transfer case to install a set of 4.7 gears.  The case was working fine prior to this tear down and I would like to reuse as many of the bearings as possible.  I did a fair bit of searching to try and find the proper way to clean and re-lube bearings.  The best thing I could find was to use "light oil" or kerosene to clean and re-oil. 

So my 2 questions:

1) Does anyone have any suggestions on cleaning and re-lubrication of t-case bearings?

2) Are there any mandatory bearings that should be replaced prior to reinstallation?

And a photo for looking:

Brake cleaner works in a pinch, solvent tank works better and a hot tank works best. For easy cleaning with minimal tools just get some solvent, a course paint brush, and a bucket. After scrubbing them in the solvent bucket use compressed air to blow them dry, wear safety glasses and don't spin the bearings with the air pressure, it's possible to spin most bearings fast enough with the air for them to explode or come apart (flying bearing bits don't feel good when they hit you). Also make sure none of the bristles from the brush came off and lodged in the bearing

When you reassemble everything give the bearing internals a lite coating of gear oil
