The front differential pinion has to be inline with the drive shaft. That's it. Not the case, the shaft. Looking at your diagram - if I'm reading it correctly - you need to rotate the front differential 2.3 degrees counter clockwise when viewed from the driver side.

I don't understand. I know you can't clock the t-case, but that's not where the problem is. You need to rotate the front differential. How can you not do that? There shouldn't be anything in the way that would prevent that. All you should have to do is modify the brackets that hold the front differential or make new ones.

That seems to be Tom's solution to everything. I talked to him several years ago. He wanted to do the same thing to mine. Ended up spending $500 here on the solution you have now - only my stuff is aligned correctly. Did he bother to tell you that that solution is more prone to vibrations than what you have now?
