What causes steering wheel hard to turn

Tap the bottom of lamp sharply hard (but not sufficiently hard to break or damage it) to jolt it a bit.
Reattempt to tirn bottom counter clockwise: should turn.

Otherwise, increase the hard jolt tap ( not hard to beak it though) and retry

Last option, try turning clockwise first to see if bottom shifts at all. Then, return to counter clockwise turn

Possible causes for a stiff steering wheel are a loose or damaged power steering belt, low power steeringfluid levels, a damaged or leaking power steering rack or a broken power steering pump.

Try to wiggle the steering wheel side to side quite hard when turning key

The ignition key won't turn likely because the shifter linkage that locks the key in OFF is worn or loose. Move the shifter linkage hard to the Park position and the key will turn. Have the linkage adjusted and the worn parts replaced

Have you checked the power steering belt and the fluid level in the power steering reservoir? The belt may be slipping or the hard turn may have caused a leak in one of the hoses that power the unit.

if it turnes over hard it is probably your timimg you can losen the bolt on the distributor and turn it down just turn it clock wise a quarter inch are so and try it if still hard to crank turn a little more it may be easier to have someone put a timing light on it.

make sure the reservoir is full then turn the wheel hard right then hard left a few times,should clear any trapped air in system....otherwise check pump for leaks.....

hi there this sounds to me like your oil level indicator is saying the oil is low, if this is not the case you need an oil change.
or to stop hard turns and hard braking lol.

Hi,
Intermittent hard power steering, at the begining of the turn of the steering wheel, once disturbed past the hard part, works normal.
Had fluid change, I notice a sensor, on the control block tower of the rack, is this at fault ? thanks buckleyeng.
