Power Steering Repair in Fairfax, VA

Power Steering Helps Make Every Turn Easier to Control.

The power steering system reduces the effort required to turn the steering wheel, especially at low speed or while parking.

Depending on the vehicle, steering assist may come from a hydraulic pump, an electric motor, or an electro-hydraulic system.

When assist weakens or disappears, the vehicle may still steer mechanically, but the wheel can become much harder to turn.

At Nutley Street Service Center, we diagnose the assist system before replacing major components such as the pump or steering rack.

Power Steering Repair Can Involve Several Different Components.

Hydraulic Systems Depend on Pressure and Fluid Flow.

Traditional hydraulic power steering uses a pump to circulate fluid under pressure.

That pressure assists movement inside the steering gear or rack when the driver turns the wheel.

Low fluid, leaks, pump wear or internal steering-gear problems can all reduce assist.

A Noisy Pump Does Not Always Mean The Pump Needs Replacement.

Low fluid can cause hydraulic pumps to whine because air enters the system or the pump cannot maintain proper fluid supply.

Contaminated fluid, restriction, belt problems or internal pump wear can also affect pump operation.

Fluid level, leaks and drive-system condition should be checked before condemning the pump.

Low Fluid Usually Means The System Needs More Than a Top-Off.

Hydraulic power steering is designed as a contained fluid system.

If the reservoir repeatedly becomes low, fluid is likely escaping somewhere in the system.

Adding fluid may temporarily restore assist, but the leak source should still be identified.

Pressure and Return Lines Can Develop Leaks Over Time.

Hydraulic systems commonly use both high-pressure and lower-pressure fluid lines.

Age, heat, hose deterioration, fitting problems or physical damage can allow fluid to leak.

Leak location should be confirmed because fluid can travel across nearby components and make the source difficult to identify visually.

The Steering Rack Can Be Part of the Power-Assist System.

On hydraulic rack-and-pinion systems, pressurized fluid assists movement inside the steering rack.

Internal seal wear can allow fluid leakage around rack boots or other areas.

Rack replacement is a major repair, so the source of leakage and steering symptoms should be confirmed before replacement.

Some Vehicles Use No Power Steering Fluid at All.

Electric power steering uses an electric motor to provide steering assist.

Depending on vehicle design, the motor may be mounted to the steering column, steering gear or rack.

Sensors, wiring, power supply and control electronics can all influence assist performance.

An Electric Steering Warning Should Be Diagnosed, Not Guessed At.

A warning light may indicate that the electric power steering system has detected a fault.

Low system voltage, sensor issues, motor concerns, wiring faults or control problems can potentially affect electric steering assist.

Diagnostic information and electrical testing help identify the actual cause.

On Some Vehicles, the Pump Depends on The Accessory Drive Belt.

A hydraulic pump may be mechanically driven by the serpentine or accessory belt.

Belt slippage, a failed tensioner or a broken belt can reduce or eliminate steering assist.

If steering suddenly becomes heavy along with charging or A/C problems, the accessory-drive system may deserve immediate inspection.

Heavy Steering Does Not Automatically Mean The Power Steering Pump Is Bad.

Low hydraulic fluid, a slipping belt, steering-gear binding, electric assist failure or other mechanical steering concerns can all increase steering effort.

Tire pressure and suspension problems can also influence steering feel.

Diagnosis helps determine whether the problem is truly in the assist system.
