I have a 1997 gmc jimmy with a 4.3 v-6. The miles are 99,386. The 4 wheel drive buttons light up when pushed but it is still spinning in 4 lo and 4 hi but I can hear the motor moving do you think it is the whole transfer case or just the motor. Also it has before at highway speed sounded like a high pitch whining noise that got worse when I hit the brakes but if I hit the 4 hi button it would stop the noise. The noise came from the front passenger wheel or front end area
