Apart from checking lock to lock, check for dryness. If it's dry around the seals, this is good.
If it's a greaseball, you may want to consider a rebuild kit. There's plenty of Youtube vids showing how to rebuild one of these boxes. Just need a pitman puller and some basic tools. Oh, and a rebuild kit. KEEP TRACK OF YOUR BALLS!!!!!
