Changing your shocks should help with the rear end sag and / \ arrangement of the wheels. The rubber boots over the constant velocity joints in the rear axles are pretty rugged. The exterior can look a little worse for wear, but if they still seal the grease inside, and keep the dirt and water on the road outside they are as functional as they can be. If grease is leaking it is apparent. 100k miles is not an identified endurance limit and changing the boots is an ordeal, so I would tend to leave it alone until you see leakage.

If you don't know when the differential fluid was last changed, and you go through the trouble to check the level, just change it. It can only help.

Clunking can be from a variety of things, and I guess I can't point to anything in particular. Hope this helps, and good luck, Jim
