    I've got a 2008 GMC 2500 that will not change from 2x4 to 4x4 or from 4x4 hi to 4x4 low or vice versa when plowing. Basically won't change at all. After the truck sits over night in the garage, it will work. Any suggestions on where/what to look at first???

    Thanks!
     
  2. Front axle motor back to the dealer for it if under warranty or spend the 50 bucks

    Ok thanks. I will pass this tip along to my mechanic. I doubt something like that would be covered under the 100k mile drivetrain warranty. I'm way over the 3 yr/36k bumper to bumper.

    Encoder motorThumbs Up If it were the front axle actuator it would come OUT of 4x4 and go from 4hi to 4low just wouldn't go in 4 anything
