I replaced the malfunctioning “thermal actuator” with the “Warn” Vacuum actuator setup, it’s been working great for about 7 years now, simple install, if I remember correctly, it was about $150.
That’s what engages the front diff into 4wd.

yes you have to drop the tank. you will also need a fuel line tool to unhook the fuel lines. before you drop the tank see if tou can reach and wiggle the electrical connection on the top of the tank. these pumps have a pigtail issue. please rate

There is a vaccuum operated switch located on the transfer case that sends vaccum to the accuator that pulls a cable that locks the front end in. Check for vac coming in and out of this switch if no vac out replace it. This switch is a very common problem. You can find them at most parts stores in the help section #49315. please rate.

You probably have blown drive hubs. Do you have to engage the hubs at the wheels? If not and they are automatic locking and they are probably blown or seized into the unlock position. They are not too expensive to replace with manual locking hubs (My Suggestion) but the autolocking hubs are expensive. When you take the caps off the front drive spindles and try running it again you may see the axle turning inside but not the wheel. That is the best test. Wish you luck!!
