rear end rebuild question...

I am rebuilding my traction lock and have the carrier out with the ring gear and bearings still attached. All other parts such as spider gears I have cleaned with an engine degreaser followed by brake cleaner.

I do not plan to take the bearings off. Is it safe to clean them with degreaser then brake cleaner?

I was thinking it may be safe because they are probably packed with grease, which leads me to my next question. Do I have to pack these bearings with grease, and if so, what specific type.

Thanks alot guys

ok, thats exactly what I was thinking of doing, thanks guys
