How do you unlockthe steering wheel after you'd tryed what the manual say's and it doesn't work cause the tires are straight not left or right

Unless you have had an accident or Kerbed the wheel it is probably your tracking is out/ track rod end loose!

It means that your front end is out of alignment. The front wheels should be adjusted so that both point slightly inwards at the front of the car when the steering wheel is straight. This is referred to as "toe-in." The reason why cars and trucks are aligned with toe-in is because the wheels go to a straight position when traveling on a highway due to the road resistance pushing the tires back. What you have is a "toe-out" condition which will cause the tires to wear faster at the side adjacent to the back of the wheels. Have your car aligned to avoid such uneven wear.

Here is the Technical Service Bulletin that maybe of help, worth looking into but can't guarantee that it would fix your problem Steering - Steering Column Clunking When Turning TECHNICAL Bulletin No.: 01-02-32-001P Date: November 25, 2009 Subject: Clunk Felt/Noise Heard From Steering Column, Steering Gear and/or Front Of Vehicle During Turning Maneuver and/or Steering Wheel Rotation (Replace Intermediate Shaft As Directed) Models: 2001-2004 Buick Regal 2005-2008 Buick Allure (Canada Only), LaCrosse 2000-2008 Chevrolet Impala 2000-2007 Chevrolet Monte Carlo 1998-2002 Oldsmobile Intrigue 2004-2007 Pontiac Grand Prix Supercede: This bulletin is being revised to add the 2008 Buick LaCrosse/Allure. Please discard Corporate Bulletin Number 01-02-32-001O (Section 02 - Steering). Condition Some customers may comment on a clunk type noise coming from the front of the vehicle while driving during a turning maneuver.
1. Locate a large area (parking lot) where the vehicle can be turned in a tight circle. 2. Turn the steering wheel to the right and/or left all the way to the steering lock, then off the steering lock a 1/4 turn. 3. Drive the vehicle approximately 5 km/h (3 mph) in a circle, preferably over rough pavement or seams on the road surface. 4. Drive the vehicle straight ahead at idle speed while applying and releasing the brake pedal. Listen/feel the steering wheel for the clunk/noise condition. 5. If a clunk is felt in the steering wheel, the MOST likely cause is the I-shaft - not the steering gear. Continue with the correction. Correction DO THIS - Replace the intermediate shaft DON'T DO THIS - DO NOT lube the intermediate shaft Replace the existing intermediate shaft

Please check for a dragging LF caliper. Then be sure the front tires are at the same PSI. Then be sure the problem is not caused by the tires.*
Miss matched BRANDS,sizes or unusual wear patterns on one or both tires will cause a pull.
Tires look good? Rotate them,one side at a time until pull goes away.
Also, to see if it IS a tire problem,swap left to right and see if it pulls to the right.Easier to do that,first.

One more test: With you hands off of the steering wheel,start the car. If the steering wheel jerks to one side,you may have a bad /plugged spool valve inside the rack and pinion.

* I have seen that happen with NEW tires.

i should worry about the steering alighment first,when the st/wheel is @ 12 o.clock gheck to see if wheels are straight.

This needs to be done with special equipment, if you adjust it with out a front end alignment machine hooked up everything else will be out and you will wear out you tires and cause other problems with vehicle handling.

swap the tire from left to right if the opposite happens then you have a tire pull this is known as a radial pull and the fix is either you rotate front to rear or a new set of tires

Hello Mohamede.

Not sure what your question is here.

I will post a couple of common issues with the Elantra steering problems.
Hopefully one of these following problems will assist you.

1. SERVICE TIP - POWER STEERING OIL PUMP WHINE NOISE DESCRIPTION:
Before replacing a power steering oil pump for a "whine" noise condition, check the oil pump reservoir filter screen for contamination. If the filter screen at the bottom of the oil pump reservoir is clogged, it may cause the pump to aerate and cause a "whine" noise.
If the filter screen is clogged, replace the reservoir and reconfirm the condition.

ABSOLUTE STEERING POSITION (ASP) CALIBRATION FOR ELECTRIC POWER STEERING (EPS) DESCRIPTION:
This bulletin provides the Absolute Steering Position (ASP) calibration method for 2007-2009 ELANTRA (HD) and 2009 ELANTRA TOURING (FD) Electric Power Steering (EPS or Motor-Driven Power Steering). This procedure is required when the battery is discharged or after the battery or EPS-related parts are replaced.
NOTE:
If the EPS ASP calibration is not conducted when the battery is discharged or after the battery or EPS-related parts are replaced, the EPS and or Electronic Stability Control (ESC) warning lamp will be turned on and the automatic EPS return-to-center control will not be performed. VEHICLES AFFECTED:
Model: 2007-2010 ELANTRA (HD), 2009-2010 ELANTRA TOURING (FD)

DIAGNOSIS AND CORRECTION OF VEHICLE PULL This bulletin supersedes TSB 05-50-012 to include 2009 models
DESCRIPTION:
Several factors may cause vehicle pull, both vehicle related and external conditions. The purpose of this bulletin is to assist in identifying the vehicle related conditions that cause pull and how to correct those conditions.
CAUSES OF VEHICLE PULL:
Vehicle pull is the tendency of the vehicle to drift right or left while driving in a straight ahead direction on a straight road at a constant speed with no pressure on the steering wheel. This pull or drift may be gradual and can always be compensated for by inputs through the steering wheel. One or more of the following conditions may cause the vehicle to pull:
Non-vehicle conditions that may cause the vehicle to pull:
^ Cambered road surfaces - Most highways are built with cambered or "crowned" surfaces to drain rain water. Sometimes the road camber is visually noticeable. Other times, it is not. The vehicle may tend to pull to the left or right, depending on the camber of the road surface. ^ Cross-winds - A sometimes overlooked, yet possible cause of steering drift is cross-winds. Side winds at higher vehicle speeds may cause vehicle pull. Please do not rule out cross-winds when diagnosing a vehicle pull. Vehicle pull caused by these two conditions is not related to vehicle adjustments and no repair should be made.
Vehicle conditions that may cause the vehicle to pull:
^ Tire inflation pressure - As small as a 2 pounds/square inch tire inflation pressure difference between the right and left tires may cause a vehicle to pull. Be sure to check the tire pressure before the tires are warmed up prior to attempting more extensive diagnosis. ^ Wheel alignment - Slightly out of specification wheel alignment causes very few vehicles to pull. Therefore, if the vehicle wheel alignment has been adjusted as close as possible to specification, DO NOT attempt to correct the vehicle pull by changing the wheel alignment angles by bending suspension components or other non-approved methods. ^ Uneven brake adjustment - If one of the four brakes is dragging, the vehicle may pull to the side of the dragging brake. Verify that none of the brakes are dragging and that they are adjusted correctly prior to attempting more extensive diagnosis. ^ Incorrect vehicle trim height - If the trim height of the vehicle is not equal on all sides, the vehicle may pull to the side of the lower trim height. Check and adjust the trim height of the vehicle as necessary. Please note that a slight variation in the vehicle trim height seldom causes a noticeable vehicle pull.
^ Tire construction - The way in which the tire is built can produce vehicle pull. An example of this is the placement of the under tread belt. An off-center radial tire belt can cause the tire to develop a side force while rolling straight down the road and the tire will tend to roll like a cone. To correct this condition, please use the flow chart. This chart provides the sequence of procedures designed to be performed for all conditions of vehicle pull. ^ Tire size - Different size tires or different make of tires, on either axles, may cause a vehicle pull.

that person is correct. remove the wheel and look at the tie rods. this vehicle uses a rack and pinion system so look at the rod connecting the rack to the outer tie rod. you will more than likely endup replacing the inner tie rod. then take it to an alignment shop and get it aligned.

Drive slowly down the middle of a straight road, let the steering wheel go and apply the brakes. If the car wants to turn by itself check your ball joints and shocks. If the car remains straight you may have an irregular wearing tire which causes it wonder at higher speeds.
I hope this helps
