Since you had the final drive out, the driveshaft most likely came out with it?
Make sure that the universal at the engine side of the driveline is connected. (Under the accordian boot.
Since you are new to gl's, you may not have gotten the rear wheel assy far enough to the right to engage.
Check the u-joint first.

If you can wait a few minutes, I'm editing some pictures that will make this process much easier. Relax, you're okay at this point. See ya soon.

This is what you have.
The ujoint probably came off the engine. The accordian boot has a spring to hold it tight to the engine case. Roll the spring forward onto the engine and pull the boot back. You should now be able to manipulate the driveline and ujoint into place. But don't do it yet, more pictures to follow.

Sorry, ran out of sand....

I know you've seen this end. The red arrow shows a seal. Make sure this seal is intact. Not deformed or torn.

The seal rides against the inside of the barrel on the diff. The yellow arrow indicates two holes that allow diff gear lube into the bell area to lubricate the splines. If the seal is torn, fluid will travel up the driveline to the boot you just pulled back and leak all over.
Pack these two holes with the moly 60 you used to lubricate the diff gear teeth. Lubricate the rear splines well. If there is a reasonable amount of moly lube, and the seal looks okay, then it is not "necessary" to replace the seal. You also need to lubricate both ends of the ujoint with the moly.
Lastly, tighten the axle to the correct torque, and THEN tighten the four bolts that hold the diff to the swingarm.

Good deal. Now zip over to Sutter's Mill and buy me a cherry coke. And when you get back, let us know if the noise is gone, or has changed.
