Hi, having trouble with my 03 Silverado 2500 HD. Whenever I put it into 4WD at a low speed, it moves really slowly at high revs, and if I put the foot down it jumps a foot forwards and stops. Engine doesn't cut out, though.

Anybody had this issue? Am I in trouble?

Thanks for any advice you can give

are you in low range and on dry pavement, cause if you are your gonna break something...........do not use 4x4 on dry roads it will 'hop' in the front, the front wheels need to slip......low range is suppposed to be high revving and slow speed, hence the crawling......if you floor it in 4 lo fo sure the truck will launch forward and basically stop as soon as you let of the gas......use high range unless your pulling a boat from a launch or something......

dont know if I undrstand your post, but ya.
