Why is steering difficult when I try to turn to the right or left? We've eliminated power steering fluid leaks,tie rods and ball joint being the cause.
At first, turning the wheel and it not responding, was an occasional occurance, but by the time we took the car into the dealership who said they couldnt find a problem, turning right and turning left were both difficult. There's no problem going forward. There was also a sound like you hear when a playing card is attached to a child's tire spokes, coming from the vicinity of the glove compartment area when we first turned the AC on.

steering rack or gear . 2X2 - 4X4 engine . Depends on steering system .
When you turn the steering wheel, the steering gear rotates the pitman arm which forces the relay rod to one side. The tie rods connect to the relay rod with the ball studs. The tie rods transfer the steering force to the wheels. Use the tie rods in toe adjustments. The tie rods are adjustable. The pitman arm support the relay rod. The idler arm pivots on a support attached to the frame rail and the ball stud attaches to the relay rod.
The 2 tie rod are threaded into the tube and secured with jam nuts. Right and left hand threads are used in order to permit the adjustment of toe.

Power Steering System Description and Operation (w/o Electro-Hydraulic Steering)
The hydraulic power steering pump is a constant displacement vane-type pump that provides hydraulic pressure and flow for the power steering gear. The hydraulic power steering pumps are either belt-driven or direct-drive, cam-driven.
The power steering fluid reservoir holds the power steering fluid and may be integral with the power steering pump or remotely located. The following locations are typical locations for the remote reservoir:
• Mounted to the front of the dash panel
• Mounted to the inner fender
• Mounted to a bracket on the engine
The 2 basic types of power steering gears are listed below:
• A recirculating ball system
• A rack and pinion system
In the recirculating ball system, a worm gear converts steering wheel movement to movement of a sector shaft. A pitman arm attached to the bottom of the sector shaft actually moves one tie rod and an intermediate rod move the other tie rod.
In the rack and pinion system, the rack and the pinion are the 2 components that convert steering wheel rotation to lateral movement. The steering shaft is attached to the pinion in the steering gear. The pinion rotates with the steering wheel. Gear teeth on the pinion mesh with the gear teeth on the rack. The rotating pinion moves the rack from side to side. The lateral action of the rack pushes and pulls the tie rods in order to change the direction of the vehicle's front wheels.
The power steering pressure hose connects the power steering pump union fitting to the power steering gear and allows pressurized power steering fluid to flow from the pump to the gear.
The power steering return hose returns fluid from the power steering gear back to the power steering fluid reservoir. The power steering return line may contain an integral fin-type or line-type power steering fluid cooler.
In a typical power steering system, a pump generates hydraulic pressure, causing fluid to flow, via the pressure hose, to the steering gear valve assembly. The steering gear valve assembly regulates the incoming fluid to the right and left chambers in order to assist in right and left turns.
Turning the steering wheel activates the valve assembly, which applies greater fluid pressure and flow to 1 side of the steering gear piston, and lower pressure and flow to the other side of the piston. The pressure assists the movement of the gear piston. Tie rods transfer this force to the front wheels, which turn the vehicle right or left.
Your best bet , take it to a qualified repair shop.
A squeak or a whining noise? If it is a squeak then it is something mechanical from your steering column down. Could be anything from rack and pinion to the tie rods and ball joints. If it is a whining noise the you need to check your power steering fluid and power steering pump. If the fluid is low then you have a leak in the power steering system somewhere and needs to be fixed before you ruin the pump.
A wobble in the steering is more likely to be one of
- loose wheel nuts
- loose hub nut
- worn steering tie rod outer joint
- worn steering tie rod inner joint
- loose steering rod universal
- worn steering knuckle ball joint
Out of these a worn or loose steering tie rod joint is most likely. If you can, jack the front of the car up and rest it on axle stands, NOT just on the jack, then have one person shake the front wheel back and forth while holding it at 9 and 3 o'clock, while another holds the steering wheel still. Then look at and feel each joint to see if you can locate the looseness.
It can be many different parts that could cause the noise. Low on power steering fluid, worn or loose belt, defective constant velocity joint, defective wheel bearing, defective rack and pinion steering, worn steering parts (tie rod ends, ball joints, idler arm, etc.)
Most likely solution to this problem is a binding ball-joint or broken/severely worn tie-rod.If the other wheel is turning back to the original state then the pump is working correctly. #6 is the ball joint. The tie rod is a long piece attached just above the ball joint should be encased in a rubber boot. If the pump is working then I would suspect one of these parts is binding up. It cant be the power-steering rack because the other wheel is moving in back and forth just fine.
First, when diagnosing any suspension steering stuff a good place to start looking is to see if you have any loose or worn parts in the front end of car.,
Jack each tire off ground, give it a pull up and down, and side to side and see if there is any clunking or any excessive play side to side or up or down. If there is, have a friend repeat the movements and look with at the ball joints, tie rod ends, and struts. Check for wetness around the tie rods. This could mean you have a steering rack issue. Next, check fluid level and color in power steering resevoir under hood. If dirty have this flushed.
Hope this points you in the right direction. Good luck!
your power steering pump has a cap on it.you have cold mark and hot mark.when car is cold engine not running.when you remove power steering cap it should be on cold mark.if not add until you get to cold mark on cap stick..dont over fill or you blow the seal.now when engine is hot been running.turn off car check.power steering cap should read full hot.mean level is correct.when you first check power steering fluid and it was real real low.you got a leaking high pressure hose.or power steering pump seal is leaking.if all check out good.your problem could be low tire pressure.worn ball joints.and tie rod ends.rack and pinion steering gear binding.
check power steering fluid if real real low you have a leak at hoses or pump seals.if all is good check for low tires and lack of lubrication to at ball joints and tie rod ends. if all is good you have power steering pump failure.
