It is the " + " that snapped and that peice of the cross is still on the rear drive shaft and the other peice is still connectd to the rear differential pinion flange, and leakage is shown coming from the location of pinion flange. Also, do I have to reinstall the whole driveshaft so the rear broken " + " will line up with other broken peice on the pinion before I make the markings.

I believe the + you are refering to is the universal joint. That is a replaceable part. Using a hammer, tap the broken parts from both the drive shaft and the pinion. For directions to replace it, go to our home page under the DIY section. It isn't hard to do. However, if the pinion seal is leaking, thta requires more work. You need to remove the pinion shaft which requires the differential to be taken apart. Note, it is common for them to seep a little as they get older. If it isn't a bad leak and the differential fluid is still full, I wouldn't too concerned about it.
Let me know if you have other questions.
