TRANSFER CASE STUCK

I Just Bought The Truck Listed Above Silverado And The Floor Mounted Four-wheel Drive Shifter Is Stuck And Won't Move At All.

I Cant Get My Truck Out Of 4 Wheel Drive. It Has The Automatic Push Button For 4 Wheel High And 2wheel Low. It Should Come Out Of 4 Wheel On...

I Makes A Load Grinding Type Noise On The Front Right Side In 2wd. But I Goes Away When I Put It In 4 Wd. What Part Keeps The Blazer In 2wd...
