You told me that the 4 wheel drive was not fully completely disengaged. So you are saying that when I put my truck in 2 wheel drive that it is half in 4 wheel and half in 2 wheel right. Well I know for a fact that 2 wheel works and the 4 wheel works. Are you saying when I put it in 2 wheel that the axle is still lock on the front? All my 4 buttons work on the dash. I need to service the transfer case. Thanks

Hello, I'm Danny.

Here is the information you requested. The vehicle when in 2 wheel drive just has the rear differential being used. When you engage the 4 wheel drive system by using the transfer case to engage 4x4 function an electric actuator engages the front differential to engage the front differential to become used. This video shows the job being done on a similar car but the process is the same.

I've attached picture steps below on how to change the transfer case oil on your vehicle including what type to use. Hope this helps and thanks for using 2CarPros.
