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.

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.
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". Hope this helps, -Dayne
Usually two - on the front wheels.
Turn your front wheels into the curb in case the parking brake fails.
Wheels facing TOWARDS the curb.
When parking uphill on a street with no curve, you should position your front wheels away from the curb or edge of the road. This is to prevent your vehicle from rolling into traffic if the parking brake fails.
back wheels.
For the front wheels to point different directions there is something bent, broken, or disconnected in the steering linkage or front suspension.
Buckle defined: To bend; to cause to kink, or to become distorted. Low air pressure would be the reason for the front wheels to "buckle"
