That is great news!
With the discovery of the 2nd front torque tube bushing, I have to say your project was very unique.
Its not everyday that you find out someone did something out of the ordinary.
I'm still not 100% sure why someone would install two front bushing.
At least it is something to warn people about in future Okie bushing installations.
Now we can say' We have seen that before.
You never know what you're going find when you open a can of worms.
With all the problems, I forgot to ask did you use locking clips on the u-joint cap screws/bolts?
My truck never had them.
As for the tweak in the torque tube you should have no worries.
The ball housing will keep everything straight.
The only other thing I would check is for a leak where the torque tube slides into the rear cast iron carrier housing.
PictureI would like to see more photos of the procedure.
The how-to article sounds like great idea.
