Power Steering Problems: Heavy Steering, Noises and Leaks

Power steering makes turning the wheel easy, especially when parking. When it starts failing, you'll notice it quickly.

Two main types

• Hydraulic power steering uses a pump driven by the engine belt, with fluid and hoses.

• Electric power steering (EPS) uses an electric motor and sensors. Many newer cars, including many Japanese imports, use EPS.

Symptoms of power steering problems

• Steering that suddenly feels heavy

• A whining or groaning noise when turning (hydraulic)

• Steering that feels jerky or notchy

• Fluid leaks under the front of the car

• A power steering warning light (common with EPS)

• The steering wheel not returning to centre properly

Common causes in hydraulic systems

• Low fluid from a leak in hoses, the pump or the steering rack

• Worn pump making a whining noise

• Slipping or worn drive belt

• Old, contaminated fluid

Common causes in electric systems

• Low battery voltage or charging problems

• Faulty torque sensor

• Wiring or connector problems

• Motor or control module failure

EPS faults usually store codes, so a scan helps find the cause.

Checking the fluid (hydraulic only)

With the engine off, check the reservoir level against the marks. Use only the fluid type your manufacturer specifies. Some cars use automatic transmission fluid, others need a specific power steering fluid.

Don't ignore it

Driving with low fluid can damage the pump. Heavy steering at the wrong moment can also be dangerous. Have power steering problems checked early, when the fix is usually simpler and cheaper.
