OK....It was suggested that I check the output shaft end play in the attempt to isolate my high pitched noise....
So this is how I did it, while the T/C is still in the jeep...
I gave the shaft a couple of good raps with a copper faced knock-off hammer (wire wheel type)
I set up my new

dial gauge and then pried behind the nut to move the shaft rearward...
I get .004.....004 to .008 is the range....
I have one more shim, it's .002.......
Should I install the shim, or call it good?
