#1. If you have a 203 that is full time. Yes/ No, If you have a part time case, just make sure that the hubs are unlocked and you should be ok.

#2. I have heard of people driving 50+ miles on the front end only, but thats only because they had to.

My Chevy isn't broken, its just out of gas.

-When I bought my '81 blazer it had 2 different gear ratios in it....(we won't talk about the last owner)

....but I drove it (in 2wd) for about 300 miles to my uncles' place so we could swap axles, just when you put it in 4 wd it would try to go sideways..but in 2wd it was okay...I drove it about 300 miles (was probably hard of the diff's though, I don't know)

As for driving it in front wheel drive only I'm not sure of....the only time I did that was when I broke my rear driveshaft wheelin' one time, drove it back to "base" (about 2 miles away) it did fine, but that was at low speeds....

You can drive a truck with two different gear ratios with no problems as long as its in 2WD. As long as its in 2WD and the hubs in the front are UNLOCKED you should have no probs. If your really worried about it though you can remove the front drive shaft. If you have an NP203 transfer case REMOVE your front driveshaft before you drive it.

As long as you dont puy it in 4 wheel drive you are fine with having different gears front and rear. If you put it in 4WD you will destroy the transfer case. As for driving with the front driveshaft you should be ok as long as you dont have a slip yoke driveshaft in the rear.

With a 203, I have heard that when you pull a drive shaft, you also have to use 4Loc or I guess the x-case differential slips like being in nuetral. Fortunately haven't had the necessity to find out for sure.
