1998 GMC K-1500 Z-71, The 4WD is engaged all the time even when manual shifter is in 2WD. When you accelerate from a stop, it makes a grinding/roaring noise. It feels like a motor mount is broke but they are fine. When it makes this noise the 4WD drive indicator light comes on , when noise stops, light goes off. While drving ,it IS still iin 4WD. I have replaced drive axles, actuator, and u-joints. Can any one help with my problem, i am running out patience and its hunting season.. HELP!

I believe you have a weak or broken motor mount, and maybe a trans mount as well.
