Yes because to remove it all and start to fix it there is a lot of labor involved. The removal and install shouldn't take an experienced mechanic more than an hour each way. Then once you open a T-case that needs one part you will find more like worn bearings, slack chain etc. which will all add up to a lot $$$. So unles someone is real handy and it doesn't have to go to a shop you should be good.
Do you know any other Jeepers who wrench on their rigs?? Do you have a Jeep club where you might find some help??
