i have a 92 ranger 2.9L v6 manual with 4WD automatic locking hubs. a few times now when i start it up the 4WD light is on (even though i did not previously have the 4wd on) and will not turn off if i hit the button. if i shut off the vehicle then turn it back on the light will go off but the 4WD is still engaged. also when it is in 4WD it whines loudly and when i come to a stop and have it in neutral it will not roll and feels like i am holding the brakes which leads me to believe that there is no fluid in either the transfer case or the front diff and sh!t is wanting to or is already siezed. i dont even use the 4WD so what would be the best way to going about disabling it? also anyone else experience these problems or have an idea as to what it could be? i would rather fix it then just disable it. the truck is just a winter beater and has 175,000 miles on it and i will be selling it soon.

You could take the front drive shaft off to disable it. You could also do some fluid flushes on the differential and transfer case to see if it actually is out of fluid and put some fresh in there.

You could also crawl underneath and manually shift the transfer case with a pliers/ vise grips. I don't know exactly what you have to do to do that cuz I never had to do it.
