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.

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.

It does not seem that sufficient diagnosis was done. No, you cant give a specific diagnosis like that without tearing unit down. It's likely that they told you the most common failure and left it at that. Likely there is a problem with your unit...I think this becomes more of a trust issue than a mechanical one. A second opinion from an independent reputable shop may help but either way, you need to have it fixed. In not using it much, it makes me wonder how it got worn.

I have the same problem and its in the front axle..Sounds like its in the t case but its the front axle.Make sure all your tires are the same size and same air pressure and the inner front axle seals are not leaking any fluid..
