Grinding noise form tc

My 4x4 wasn't working so I bought the infamous switch. The switch fixed the 4x4 but most of the time if I shift from 4lo to 4hi it makes a loud grinding noise. But if I just go from 2wd to 4hi it works fine. And sometimes it won't make the noise but after about 5 feet of driving it starts to make that noise. What could be making this noise?

Do you have an auto or manual tranny? Always shift from H to L with the tranny in either P or N (or with the clutch pressed to the floor) and with the vehicle stopped. Going from L to H is the same procedure.

Did you mean it grinds in 4L? What transfer case is it? There should be a tag on there (on the case) saying... [img]/wwwthreads_images/icons/crazy.gif[/img]

I'm sorry, I didn't give any info. It's a 93, 4.3l, automatic trans, pushbutton transfer case. Not sure of the modle number. When it makes those grinding noises the speedometer goes up and the truck won't move even if the gas is pressed. It grinds when I go from 4lo to 4hi.
