I put two 245-75-R16 tires on the front and still had two 245-70-R16 tires on the back.
When my wife drove about 15 miles the transmission was shaking and hot. After letting the car sit for 43 hours I drove it back home at under 30 mph and it seems fine.
Question : What problems have we created in the transfer case? And is the jeep safe to drive if I put another two 245-75-R16 tires on the back, so all tires are the same size?

You should have the same size tires in the front and back. By having 2 different sizes, you are changing the gear ratios between the front diff. and rear diff. You could wipe out the t-case especially if it is full time 4wd.
There really is no way to tell if there is any damage unless you open up the t-case.
It's a good thing you din't drive very far and caught the noise right
away. There is a part in the t-case called the viscouse coupler, this
would be the part to fail if you did put a considerableamount of miles
on it. If the Jeep does'nt make any noise while driving or making sharp
turns then your ok.
For your information the viscouse coupler cost about 600.00 dollars.

The information in the answer I had already been told. The question is how do I tell if any damage has been done to the transfer case? Now that I have 245-75-R16 tires on all four wheels no futher damage will occur, but how do I tell if any real damage was done during the time that different size tires were on the jeep and it was in full time 4wd with the 1996 quadratrack?
Does the differential, overtime in the 1996 jeep Cherokee all wheel drive, become a problem. I am looking at one that has 162,000 miles on it.
