A whining noise when you turn the wheel, steering that suddenly feels heavy, or a reddish or amber fluid spot under the front of the car are the most common signs of a power steering problem. Causes range from low or old fluid to a leaking hose, a worn pump, or a fault in an electric steering system. Hillside Auto Clinic at 26122 Western Ave, Lomita, CA 90717 can find the cause; call (310) 956-5794 or schedule.
How power steering works
Power steering adds help so you can turn the wheel with little effort, especially at parking-lot speeds. Older and many trucks use hydraulic power steering: an engine-driven pump pushes fluid through hoses to the steering gear or rack. Many newer cars use electric power steering (often called EPS), where an electric motor on the steering column or rack provides the assist and there's no steering fluid at all. Some cars use an electric pump with hydraulic fluid. Knowing which type your car has helps narrow down what's wrong.
Signs of power steering trouble
- Whining or groaning when you turn, especially at low speed or when the wheel is turned all the way. On hydraulic systems this often points to low fluid or a tired pump.
- Heavy or stiff steering, either all the time or only at certain moments, like a cold start or a tight parking turn.
- Steering that feels jerky or notchy instead of smooth.
- Fluid under the front of the car, often reddish, pink, or amber, or a wet, oily look on hoses near the pump or rack.
- A squeal when you turn sharply, which can be a slipping belt on cars where the belt drives the pump.
- A power steering or steering system warning light on the dash, common with electric systems.
- Wandering or a loose feel, which can come from worn steering parts rather than the power steering itself.
Common causes
On hydraulic systems, the usual suspects are low fluid from a leak, old or contaminated fluid, a leaking pressure or return hose, a worn pump, or a leaking steering rack. On electric systems, problems are more often a sensor, wiring, a weak battery or charging system (EPS needs steady voltage), or the assist motor itself. Because several parts can cause the same feeling at the wheel, it's best to confirm the source before replacing anything.
Is it safe to drive with power steering problems?
You can still steer a car when the assist fails, but it takes much more effort, and a sudden loss of assist in the middle of a turn can catch you off guard. That's a real risk in tight spots like parking lots, driveways, and busy intersections. If steering suddenly gets heavy, a steering warning light comes on, or you see fluid dripping, have it checked before driving much farther. Running a hydraulic pump with very low fluid can also damage it.
Should you just add fluid?
If your car has hydraulic power steering and the level is low, topping it off with the type listed in your owner's manual may quiet a whine for a while. But fluid doesn't get used up on its own, so a low level usually means there's a leak somewhere. Using the wrong fluid can harm seals, and electric systems don't use steering fluid at all. A quick inspection tells you whether a top-off is enough or a repair is needed.
What a power steering inspection looks like
A technician usually starts by confirming which type of system your car has. On hydraulic systems, that means checking the fluid level and condition, looking for leaks at the pump, hoses, and rack, and checking the belt. On electric systems, it often means scanning for stored steering codes and checking battery and charging voltage. A test drive and a look at the tie rods and other steering parts round it out, since worn parts can feel like a power steering problem.
Simple ways to stay ahead of it
- Pay attention to new whines, groans, or squeals when turning.
- Look under the car where you park for new spots near the front.
- Don't hold the steering wheel at full lock for long; it puts extra strain on hydraulic pumps.
- Mention any steering changes during routine service so they can be checked while the car is on a lift.

FAQ
Why does my steering whine when I turn?
On cars with hydraulic power steering, a whine when turning most often comes from low fluid, air in the system, or a worn pump. It's worth checking for a leak, since low fluid usually means it's escaping somewhere.
Why did my steering suddenly get hard to turn?
Sudden heavy steering can come from a lost or slipping belt on belt-driven pumps, a major fluid leak, a failed pump, or a fault in an electric steering system. Drive carefully and have it checked as soon as you can.
Does my car have power steering fluid?
It depends on the system. Hydraulic and electro-hydraulic systems use fluid, while fully electric power steering doesn't. Your owner's manual or a quick look under the hood can tell you, and we can confirm it during an inspection.
What color is power steering fluid?
It's often red, pink, or amber when fresh and gets darker with age. Other fluids can look similar, so a leak near the front of the car should be checked to confirm where it's coming from.
Can a weak battery affect electric power steering?
Yes, it can. Electric power steering relies on steady voltage, so a weak battery or charging problem can reduce assist or trigger a steering warning light on some cars.
