Rebuilding them is actually very simple.
Just take them apart, get all the grease off (i use gasoline and a toothbrush to get it all off) then just re-assymble them. You dont need all the stuff in the rebuild kit. All that is is just some washers, bushings and a seal that might already be there.

Ive rebuilt and sold 4 or 5 pairs, and ive gotten it down to about 30 minutes a pair....
oh, and here is a good thread on PBB for a rebuild.

Put the AISINS on your truck, sell the SW ones.
