"Shimming the diff" refers to placing small spacers (look like washers) behind the gears to set the correct gear mesh. As the gears wear down the gap between them increases. If you place the shims properly you regain the proper mesh and increase the life of your gears. If the space becomes to great the gears will start to wear improperly and eventually chip away.

As stated above, he is correct but, most "Shims" are washers, and you usually place them behind the gear, or between the gear and the housing. As you run your truck, it slowly rounds the teeth on all the steel gears... causing a little play, just like the spur gear, if you let it go for too long, thats why people blow their diffs.... but if you Re-Mesh your gears... don't make it TOO tight... because it will do the same, wear down your gears improperly... Hope this helps...
