Re-Gearing a Jeep, 1 Diff only.. WTH?

Hello,
So I took my car to the shop to get the thermostat changed. Yes car, as in my 2006 Chevy Cobalt SS (No dead kittens here) Anyways, I was takling to the shop owner about regearing Jeep differentials.

He told me several times, customers have come in to regear ONLY the rear diff, and not doingboth. Then as soon as they hit 4 wheel, they screw their stuff up.

I've never heard of or even thought about singlediff regear.

Why would some one do that to a 4 wheel drive vehical, be it Jeep, pickup truck or Jeep Pickup truck (Comanche) or anything.

There were more than a few Jeeps in the 1970s where this was done. During the gas shortage and skyrocketing fuel prices, a number of owners re-geared the rear axle and left them be. When the vehicle got re-sold or traded in, the new owner might have gotten a nasty surprise when they locked in the manual hubs/engaged the 4wd.

Some people did remove the front drive shaft, but because that cost money and or time, many owners didn't bother.

You guys need to think outside the box. Recently I called 5+ shops for a quote to regear my rear axle. I bought a HPD30 from CL that was already geared to 4.88 when my rear axle was 3.73. I installed the new axle before regearing the rear. So I had a shop regear only my rear axle while I was running different ratios. Of course the driveshaft was off during the process. Anything is possible.

If you gotta have big tires, mall regulations do not require both differentials to be connected.

If a shop wont do what I ask I will find another shop.He doesnt know what my intentions are or what I have already done.It is not up to the shop to determine what I want its up to me.If one of my employees did that he would be looking for a job.It is OK to inform the customer of what could happen ,state it on the repair order , and say no warranty or liability implied,and make him sign it.

This however doesn't seem to make since...
Its going to cost more time/money to do them one at a time. That's two trips to the shop, ect. It would be MORE economical (if you are that strapped for money, you are going to want to be more economical) to save the money in your budget until you can afford to do them both at the same time.

I agree that it doesn't make sense, however, I have read threads where people stated they have done exactly that simply because they couldn't afford to do both at the same time.
