Yesterday on pavement , with it raining cats and dogs out I put it in 4x4 when leaving a parking lot, when reversing out of a parking spot turning the wheel the truck pretty much stops and doesnt want to go, its as if I had front and rear locking diffs as if the tires were stuck spinning the same speed.

Can someone explain this for me? I mean just because I put it in 4x4 shouldn't mean I lose limited slip, right?

Why would you need 4x4 backing out of a parking spot? If your truck slips that bad in the rain, it might be time for new tires. Read the owners manual.

Because you have a locking center transfer case. Parking maneuvers are the worst. Back up and turning your front outside tire vs your back inside tires are spinning at dramatically different speeds. Since the front and rear axles are locked to each other the inside rear tire need to slip otherwise it will bind. It is like the binding from a locked diff but even worse due to the greater size of the arc causing a larger difference in tire speeds.

Most including the manual will tell you never to do this. I and most others at ski resorts do this all the time. Parking spot is icy and on a slight slope, need 4wd to get out, yet drive isle is bare sometime dry pavement. Tires chirp all the time.

4X4 is only for use on surfaces where the wheels can slip - snow, dirt, gravel and so on. Wet pavement doesn't count. 4X4 locks the front and back wheels together, making turns on pavement difficult if not impossible.

ok cool, did not know this. I assume there are some systems out there that do not lock the transfer case?

I know some german models have 3 lockers and 1 is for the transfer case.

It was just a test, did not need 4x4 and didn't push it beyond the stuck point.

Almost all true 4wds (transfer case, hi/low) will lock the center T-case. AWDs and car type 4wds have open transfer cases or center difffs.

The inner tires turning in a circle go a shorter distance than the outer two tires and binds up the drivetrain.
Costco will not put two tires on my AWD Rogue because a new tire is taller than a worn one so they sell sets of four only OR he said bring the rims in and put them on the car yourself to get around it. Someone must have sued them for this to be company policy.
