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 siz
e tires or different make of tires, on either axles, may cause a vehicle pull.
Seems you may have a wheel speed sensor (right front) which has come apart and is rubbing up against the 'tone wheel' on the axel shaft.
