My truck doesn't have any problem engaging 4 HI from a stopped postition but will not engage if I have started driving. I can disengage while stopped or moving. When I try to shift into 4 HI while moving it makes a noise that gradually gets louder until I shift it back to 2HI then the noise gradually goes away. Any suggestions on what's wrong?
