the load might be a bit heavy so the back wheels are not on the ground enough to turn?
Stop the vehicle, turn it around and drive backwards
No. Lower the load to the floor, set the parking brake, turn off the engine.
Do not turn. If you turn, the forklift may tip.

WRONG!! a forklift is driven with a steering wheel, but the back tires direct the movement, not the front as in a car. With the back tires turning to control the turning radius, it allows you to turn literally on a dime. You can do a complete circle on a forklift without changing your center point. Depending on what size forklift you are speaking of. The above comment is refering to a forklift found in warehouses, walmart, etc.
If you have driven a long distance, your car will tend to turn on it's fan too cool down. It's not a problem!
would the tierod cause the wheel to turn out
The most likely cause is the belt on the power steering pump. This is especially likely if this occurs when the car is not moving and you turn the wheel. The load on the pump is causing the belt to slip, and squeal. Adjust the belt. If it persists you may need to replace it.
No power.
Look to the alt. belt. It may squeal under load.
