In 4WD, cannot turn lock to lock without transmission disengaging and revving engine

[Kevin Waller]

I discovered this problem while trying to pull into parking spaces; that when the 4WD is engaged I cannot turn the wheel all the way left or right without disengaging the transmission and revving the engine. This has led to several near-accidents in busy parking lots full of holiday shoppers when I suddenly stop moving and have to put my hazard flashers on mid-turn. I then put it in 2WD and park. The work-around I have come up with is to put it in 2WD after entering a lot but before trying to park, which is first off ridiculous and also not always realistically possible. I apologize if someone has already posted this issue, and will gratefully accept being pointed in that direction. I leased the truck at the end of September, well after the dealer should have flushed the transmission fluids of their entire inventory. Thank all of you for your help and I hope you are having a great day.

Are all the tires the same size?  Are some worn more than others?

 

And is the pavement ice/snow covered?

Wait...are you trying to turn while engaged in 4wd, while on dry pavement? If so you are just binding the front axle, which is a big NO NO
