Ok. I have 06 colorado I5. 4wd does engage with truck on lift but now power to front axle when in drive. Do I need new transfer case?
There are things to check before going that route. Did this problem just show up? It could be a bad actuator or switch on the transfer case. Easy fixes if your willing to try.Ok.

Try this, with the truck in drive creep forward and engage 4H. Stop and shut off engine while in drive and 4H. Shift to neutral or park and restart truck. Creep forward again and turn the wheel in one direction. If you "feel" that resistance of 4 wheel drive you most likely have a bad 2/4 switch on the transfer case.Using this method I was able to restore my truck to functional 4 wheel drive twice by replaceing that switch.Been trying to locate issue off and on for year now. Had it to a friend's garage. Seems as actuator is working. When up on lift front wheels are locked in but no power to them when in drive.
The way to tell is to see if your front driveshaft spins freely after you've engaged 4wd.Is it possible the actuator is not turning enough to fully engage and lock in front axle?
The front wheels shouldn't free wheel while in 4wd. Actually if your front axle is engaged one front tire should spin forward while the other spins backwards when turning them by hand.Ok we had truck up on a lift so the front wheels shouldn't spin freely when 4wd engaged? The front actuator was removed before and checked it was operating. We wondered if transfer case actuator wasn't working properly.
