gear ratio problems

[Moparbishi]

Ok so I am having problems with jacks transmissions. I sent it in 2 weeks ago and they finally got to it and said my center diff had some major damage. They said that it was caused by a different rear gear ratio. I have all the service records and the only thing done to my drivetrain is the transfer case recall done at 1,000 miles. I now have 100,000 miles, you would think that if I had a different ratio it would have went out a long time ago.

I checked the tcase- I marked top dead center. It took 14 turns of the input shaft for the output shaft to line up where it started.

Rear Diff says 3.545 on it- I turned the tires 9 times for the drive shaft mark to line up where it started.

No, the xfer case is just a way to sent power to the front and rear diffs. as long as the front and the rear diffs have the same ratio, the center can be different. Seems like the guys you sent your transmisson to have never worked on a awd trans.
