If you just drain all the old fluid and put new fluid in you should be fine but if you want to be very thorough...Drain all the old fluid. Put about 1/2 to 1 qt of new fluid in and roll the truck up and down the driveway once. - don't drive it, just spin the wheels a little to get the new fluid to "rinse" the inside of the housing and gears. drain again and refill. don't forget to add the really expensive additive if necessary.

When changing the rear differential lube, how should one go about cleaning out the housing and gears before re-lubing the differential?

If it gets a little dirty while you are working on it witch they do when I am laying in the dirt and the wind is blowing 20 MPH. I use a small pump up garden sprayer with solvent in it and give it a good flush just before you put the cover on
