Ignition coils for a vibration originating from the rear end.... Whut?!
OP, if you have not replaced the driveshaft bushing, I'd wager this is the gremlin that's the root of your problem. It looks like this:

It costs a whole whopping $9 dollars! - from ECS. This little devil slips on the nose of the driveshaft. Since you've been driving the car and giving the center support bearing a good workout in trying to minimize the driveshaft vibration, replacing that would be a good preventative measure. Lastly, having a worn driveshaft bushing feels like having a bad center support bearing. Have fun underneath your sled... .

Should have mentioned already replaced this as well. I did this with the center support bearing. I gotta feel like it's cv joint or the half shafts.

Driveshaft CV Joint. Youtubes online on how to repack with grease. Or the Assembly is roughly 200$ if you want to save about 4-5hrs, half a bottle of go jo, 20 or so rags and a t-shirt....unless of course youve done this a few times.

On mine the cause was the 5$ Red gasket that broke apart between the shaft and the diff flange. Be sure to put a new one of these in as well.

I have a feeling that gasket may be bad on mine. When i did the subframe job i don't remember seeing when reassembling. I'm guessing if that's gone then all the grease will just leak out over time.

yes, there will be a telltale sign of LOTS of grease spinning out of it radially all over the rear of the car...

Got the old CV joint off. It seemed ok at first but moving it certain directions seemed to make it bind up. After cleaning it and taking it apart it seems like some scoring happend and maybe this explains the issues. I ordered a new joint so i'll update when its installed.

The only catch here is that since you've dissembled the driveshaft you probably need to have it re balanced.

I would also take a very close look at the center u-joint - if there is much play the DS is junk.

I reassembled mine and had no issues w balance or vibration after.

Also u might give it a trial at repacking w grease and see if the binding is gone when reassembled. Not sure how bad te scoring was...
