No high range 4x4
Went out plowing the other night & I ran into a problem. I went to put the truck into 4wheel drive high but when I did the truck was shaking like the rears where being ripped out!! I put the truck in low & it worked fine to plow. I have not touch anything inthe drive-line since last year.Even after that the high range worked fine. I did put new rotors,pads,springs,shocks, & new tires on the front. The indicator light is not commin on for high but is for low range.Could it be something electronic or mechanical? Would fluid level have anything to do with this problem? Well any help would be great
