did you switch to two wheel drive while pressing on the gas

 

well with the help of a friend managed to figure out my issue with the 4 wheel drive. the solenoid that sits on the front axle was hangging up from grease the got as hard as tar cleaned it up shot it with some p.b blaster .i thought i broke the transfer case chain . well snow bound agian . was out playin in it today we didn,t get much but enough to have a little fun . can,t wait for a foot or two keep on truckin dave
