Your crank angle sensor is located in the distributor on the right side of the valve cover. I would venture a guess it might be time to replace it with a used one, but perhaps someone else will have more insight on that particular problem.
If your axle is clicking, sorry to tell you but it is really not fixable, I would suggest replacing it. oem ones are hard to find but the best option, you can also visit your friendly napa or advanced auto. A buddy of mine said advanced auto has the lifetime replacement for the duralast axles, which are far from oem "green" axles, but I have been running a napa for a year or two now with no problems yet.
Sounds like you got everything else under control. I would ditch the egr if your state does not smog, but that is my personal hatred of the clutter in the engine bay. And it is a project to delete it.
Keep us posted.
