Most vehicles with timing chains have a cover over the chain that it attached to the oil pan. There are gaskets that have to be replaced between the two and removal of the pan is recommended to do this properly. Trying to avoid it can result in a number of issues, from gasket material falling into the sump to oil leaks from not having the lower part of the cover sealed properly.

You do not need to remove the upper oil pan. There are 2 bolts that go through the oil pan into the front cover that has to be removed. You do not need to remove the transfer case to remove the front timing cover. After you have the bolts under the front cover that go through that lower oil pan, and the bolts all around the timing cover off, just work the cover slowly till it pops free.
do you have a 3.1L V6? The timing cover gasket seals the timing components, it is located behind the belt drive system (alt, a/c, p/s etc.) all of these components must be removed to change this gasket, also the oil pan lower seal gets changed at the same time. The oil pan gasket includes the rear pan seal and the side seals and on for the rear of the pan, the engine must be lifted out of it mounts to change this gasket. It takes time to do these repairs and each shop has an hourly rate per hour on labor. The cost of the parts will be relatively the same at any shop, labor will differ. I hope this helps to answer your questions.
