Viscuous coupling in the transfer case could be going bad.
Try putting on the emergency brake & turning the wheels one way while turning the key. If that dont work try turning the wheels the other way..if your parked on a steep hill you might even have to put a brick in front of the tires and let it roll a bit to remove some pressure from the wheels............hope it works
Possible failed U joint or cv joint at the left front wheel
A 1998 Jeep Cherokee has disc brakes in the front.
The 2011 Jeep Grand-Cherokee has 58.6 in. of front shoulder room.
The 2004 Jeep Grand-Cherokee has 39.7 in. of front head room.
The front axle is not disengaged OR the front u-joints are starting to fail.
If you are asking about the method of turning your front wheels into the curb when parking on a hill, it can help reduce the risk of brake failure.
Turn your wheels to the left.
When parking uphill on a street with no curb, the front wheels should be positioned to the right. If there is a curb, the back of the right front wheel should be turned against the curb.
Usually two - on the front wheels.
If by lock up you mean squeal when cornering, such as in a parking lot, this is because the grand Cherokee (4x4) is commonly an all-time 4-wheel drive. You can determine this by looking at the 4X4 shifter and it should say quadra-trac. When cornering, the wheels spin at different speeds which causes the computer to think it's losing traction, then engages 4X4 and locks up the front end. Thus, causing it to "bark" or "squeal".

Turn your front wheels into the curb in case the parking brake fails.
Wheels facing TOWARDS the curb.
Uphill, turn your front wheels toward where a curb should be. Set your parking brake. If the brakes fail, the wheels will turn your backend back toward the side of the road. If downhill, turn the wheels toward the curb/side of the road with parking brake on---if a failure, downhill gravity will take the car to the side rather than rolling into traffic.
When parking uphill with a curb, a driver should turn the front wheels away from the curb and towards the road. This helps prevent the vehicle from rolling into traffic if the brakes fail.
Turning vehicles ensure that the rear wheels follow the path of the front wheels through a mechanism called the steering system. This system allows the front wheels to turn, causing the rear wheels to also change direction accordingly, maintaining alignment and ensuring that the vehicle follows a smooth and coordinated path during turns.
