Power Steering Repair Cost

Cost by Repair Type

• Power steering fluid flush: $100–$175
• Power steering hose replacement: $200–$500
• Power steering pump replacement: $400–$800
• Rack and pinion replacement: $1,200–$2,200
• Electric power steering (EPS) module: $400–$1,000

Hydraulic vs. Electric Power Steering

Older vehicles (pre-2010 mostly) use hydraulic power steering — a belt-driven pump pressurizes fluid to assist steering. Modern vehicles increasingly use electric power steering (EPS) which uses a motor and requires no fluid. EPS is more fuel-efficient but when it fails the repair is often electronic rather than mechanical.

Symptoms of Power Steering Problems

• Heavy or stiff steering, especially at low speeds
• Whining or groaning noise when turning (hydraulic systems)
• Steering wheel vibration
• Power steering warning light
• Fluid leak (reddish fluid, usually near front of engine or under the car)
• Steering wheel doesn't return to center after a turn

Check the Fluid First

On hydraulic systems, check the power steering fluid level first — it's a reservoir under the hood, often labeled. Low fluid is sometimes a $10 fix (top-up + check for leaks). Dark brown or black fluid means it's overdue for a flush. If the pump whines even with proper fluid, the pump itself is likely failing.

Rack and Pinion vs. Pump Diagnosis

A bad pump causes noise and effort issues at all steering positions. A bad rack causes specific problems at certain wheel angles — noise or resistance when turning to full lock, fluid leaks from the rack boots, or looseness in the steering. A shop can diagnose which component has failed with a pressure test and visual inspection.
