Hey TCG! Looking for some feedback on an issue with my truck as it's the first vehicle I've owned with 4wd. When I'm using 4wd the truck sometimes seems like it completely falls out of gear while in motion. I can floor the gas and it just won't move. This is a somewhat new development and I didn't think much of it at first but seems to be increasing in frequency so I thought it best I pose the question to the experts. Also happens in reverse as well. Anyone know why this is or what the cause could be?
