Dear George,
It really sounds like you have bent some parts underneath the front end of the car, and the car must not be driven until this is repaired.
I suspect the tie rod ends is bent, but it could be worse.
You will need to have it towed by a tow truck to the repair garage, but you can also jack it up high in the air if you wish to see what is bent. God bless your efforts.

I have a 2006 Chevy HHR.. I have no check lights on on the dash... I am getting 11.6 - 12.4 volts on my voltage meter until I take a hard turn and the voltage goes to 13.8 - 14.9 .. Any ideas ?

That vehicle has electric power steering (EPS) system. Plus computer controlled charging system . The charging system has different modes of operation ,when just going down the road the charging system will go down 11 to 12 volts . Put a load on the system an it can charge up to 15 volts, Watch these videos ' That's normal operation.

EPS Motor
The EPS motor is a 12-volt brushed DC reversible motor with a 61-amp rating. The motor assists steering through a worm shaft and reduction gear located in the steering column housing.
Power Steering Control Module (PSCM)
The PSCM uses a combination of torque sensor inputs, vehicle speed, calculated system temperature and the steering calibration to determine the amount of steering assist. When the steering wheel is turned, the PSCM uses signal voltage from the torque sensor to detect the amount of torque being applied to the steering column shaft and the amount of current to command to the EPS motor. The PSCM receives serial data from the engine control module (ECM) to determine vehicle speed. At low speeds more assist is provided for easy turning during parking maneuvers. At high speeds, less assist is provided for improved road feel and directional stability. The PSCM nor the EPS motor are designed to handle 61 amps continuously. The PSCM will go into overload protection mode to avoid system thermal damage. In this mode the PSCM will limit the amount of current commanded to the EPS motor which reduces steering assist levels. The PSCM also chooses which steering calibration to use when the ignition is turned ON, based on the production map number stored in the BCM. The PSCM contains all 8 of the steering calibrations which are different in relation to the vehicles RPO's. The PSCM has the ability to detect malfunctions within the EPS system. Any malfunction detected will cause the IPC message center to display PWR STR (or Power Steering) warning message.

Power Steering System Description and Operation (with EPS)
The Electric Power Steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the power steering control module (PSCM), torque sensor, power steering motor rotational sensor, power steering motor, discrete battery voltage supply circuit, and the GMLAN serial data circuit to perform the system functions. The PSCM and power steering motor are each serviced separately from the steering column assembly. However, the motor rotational sensor is serviced as part of the power steering motor, and the torque sensor is serviced as part of the steering column assembly. The PSCM also monitors vehicle speed from the engine control module (ECM) via the GMLAN serial data circuit. At low speeds more assist is provided for easy turning during parking maneuvers. At higher speeds less assist is provided for improved road feel and directional stability.

After taking a turn at the light my steering wheel went so stiff I couldn't even turn the wheel. What happened and how do I fix it?

hi Justine.
There some moments when the steering wheelbecomes stiff and hard to turn. From irregular servicing, lack of fluid oil to low tyre pressure or bad wheelalignment, any of these could be the cause. ... Under normal circumstances when the car is in good condition, the steering wheel is always flexible when turning.11 Sep 2014

Power Steering System Description and Operation (Non-Turbo)
The electric power steering (EPS) system reduces the amount of effort needed to steer the vehicle. The system uses the body control module (BCM), power steering control module (PSCM), torque sensor, discrete battery voltage supply circuit, EPS motor, serial data bus, and the instrument panel cluster (IPC) message center to perform the system functions. The PSCM, torque sensor, not the EPS motor are serviced separately from each other or from the steering column. Any EPS components diagnosed to be malfunctioning requires replacement of the steering column assembly, also known as the EPS assembly.
Torque Sensor
The PSCM uses a torque sensor as it's main input for determining the amount of steering assist. The steering column has an input shaft, from the steering wheel to the torque sensor, and an output shaft, from the torque sensor to the steering shaft coupler. The input and output shafts are separated by a torsion bar, where the torque sensor is located. The sensor consists of a compensation coil, detecting coil and 3 detecting rings. These detecting rings have toothed edges that face each other. Detecting ring 1 is fixed to the output shaft, detecting rings 2 and 3 are fixed top the input shaft. The detecting coil is positioned around the toothed edges of detecting rings 1 and 2. As torque is applied to the steering column shaft the alignment of the teeth between detecting rings 1 and 2 changes, which causes the detecting coil signal voltage to change. The PSCM recognizes this change in signal voltage as steering column shaft torque. The compensation coil is used to compensate for changes in electrical circuit impedance due to circuit temperature changes from the electrical current and voltage levels as well as ambient temperatures for accurate torque detection.

What causes my 2-wheel drive ranger to vibrate hard when I turn the steering wheel at low speeds only, like pulling out of garage? also does it in reverse. makes a noise near the rear when it is vibra

i would say it is a solenoid or air in the power steering lines but you would have to put a obd2 scanner and see what it says.
if i remember correct bleeding is as simple as removing the power steering cap and turning steering all the way left hold for 5 seconds then right and hold but you will need to look at oil in reservoir and see if it is bubbling while turning and holding. you will need a helper and if it is do this for 5-10 minutes.

Where is the power steering pump located?

ELECTRIC POWER STEERING (EPS)
The TSX uses Electric Power Steering (EPS) which regulates steering via a computer-actuated electric motor. With the computer-controlled system, advanced algorithms built into the operating software allow for continuous fine-tuning of the steering assist forces so that minimal force is required at low speeds- such as when parking or maneuvering. Conversely, progressively higher steering effort is generated at higher speeds (such as when driving on the freeway) to deliver a sport-minded driving experience.
The EPS system found in the TSX is an evolution of an earlier EPS system found on the Acura NSX supercar. Its key features and advantages include:
  • The EPS system reduces the steering effort at low speeds, improving agility and ease of effort when parking or maneuvering in tight areas
  • Rigidity of the steering mount is higher, which allows a more precise and "connected" feel during high-speed maneuvers (such as during lane changes or when on winding mountain roads)
  • The EPS steering assist incorporates computer algorithms based on vehicle speed rather than engine speed, allowing TSX engineers the flexibility of tailoring the steering feel to match actual driving conditions- especially high-speed driving. The EPS steering algorithms incorporate steering assist changes for every 0.6 mph.
  • The EPS system is different (and uniquely tuned) for each of the TSX models: 2.4L I-4 sedan, 3.5L V-6 sedan, and the new Sport Wagon.
  • EPS employs a sporty, 13.5:1 steering ratio which further improves performance driving agility
  • In its evolution from the original NSX system, the TSX's EPS system uses a significantly more powerful electric motor teamed with a far more sophisticated microprocessor
  • By eliminating the conventional power steering pump assembly, EPS uses less engine power which improves acceleration and fuel efficiency
it is an electric pump without a pulley or belt or fluid apparently

Sorry but your not going to get it fxed fast ! Your vehicle has Electric Power Steering (EPS) , an electronic control module makes it work . If this module is bad an need's replacing your going to have to take it to a GM dealer to have it replaced an programmed .

EPS light is turn on how can i turn off its?

EPS

EPS: Electronic Power Steering - enables the amount of assistance with steering to be varied depending on speed and how much you turn the wheel. This means it can give lots of boost when parking the car whilst still giving you a good feel for the road at speed.

Shakes, steering wheel hard to turn. RPM's at 2 when going 15mph.

Have you checked the power steering fluid? Do the belts squeel when you turn the steering wheel?
I know this might sound silly but are your air pressures in your tyres correct? Low air pressure will cause your steering to shake at speed and it will be hard to turn at low speed.
I hope this helps,
Scott.
