Steering Gear & Power Steering Defective: Symptoms, Inspection, and Costs

Power steering is standard in cars today—and that's a good thing: less effort, more control. But if the assistance decreases, the steering becomes sluggish, or noises occur, it is often due to a power steering defect or a problem with the steering gear. Here you can find out what power steering is, how defects manifest themselves, and what the repair costs are likely to be.
 

What Is Power Steering?

Power steering assists the driver by making the steering wheel easier to turn. There are two common types:

• Hydraulic power steering: A power steering pump and power steering fluid (hydraulic oil) generate pressure.
• Electric power steering (EPS): An electric motor assists directly at the steering gear or steering column – efficient and often requiring less maintenance.
   

Typical Symptoms: Power Steering or Steering Gear Defects

Watch out for these warning signs:

• Steering is sluggish – especially when parking (often oil level/pump).
• Cracking/knocking when steering – possible play in the steering gear.
• Oil loss under the car – power steering fluid leak.
• Imprecise steering/play in the steering – may pull in one direction.
• Warning light (for electric power steering).
   

👉 Note: Always take steering gear failure symptoms seriously – driving safety is affected.

Inspection: How Workshops Proceed

1. Oil level & fluid: Is there sufficient power steering fluid? Is the specification correct?
2. Pressure/delivery test of the power steering pump (hydraulic).
3. Check steering gear play on the stage, inspect boots/seals.
4. Electronics diagnosis (EPS): Read out control unit, check sensors/motor.

Can power steering fluid simply be topped up?
Yes – but only with manufacturer-specified fluid. Leaks are a common cause of low fluid levels; in this case, simply topping up is not enough – the leak must be repaired.
 

Costs: Repairing Power Steering and Steering Gear

• Refilling oil / small seal: approx. $50–150
• Replacing power steering pump (hydraulic): approx. $400–800
• Repairing electric power steering (EPS): approx. $600–1,200
• Repair steering gear: approx. $700–1,500
• New steering gear: approx. $1,000–2,500 (depending on model)

👉 Caution: Blocked units/belt-driven pumps can cause consequential damage; in extreme cases, this can lead to side effects ranging from additional loads to engine damage.

Cost Overview for Power Steering and Steering Gear

Short Overview

Power steering (hydraulic or electric) reduces steering effort and increases safety, especially when maneuvering. Typical signs of a defect are stiff steering, unusual noises, warning lights, steering play, or oil loss. The causes range from low oil levels and defective seals/pumps to damage to the steering gear.
The inspection includes oil level and specification, delivery/pressure tests, visual inspection for play/leaks, and electronic diagnostics for electric power steering (EPS).
The costs vary greatly: from $50–150 (fluid/small parts) to $1,000–2,500 (new steering gear). As steering is safety-critical, you should not continue driving if the power assistance fails or the steering becomes very stiff.

👉 Tip: When buying a used car (e.g., from a car auction), be sure to check the steering gear and power steering—a preliminary diagnosis can protect you from high costs.

FAQs – Frequently Asked Questions About Power Steering and Steering Gears

Can you still drive with faulty power steering?
→ Possible, but not recommended: steering becomes extremely difficult, increasing the risk of accidents.

Can you drive without power steering?
→ Theoretically yes (mechanically), but risky in practice – especially at low speeds.

What type of oil is used in power steering?
→ Depends on the manufacturer: ATF or special hydraulic oil. Only use approved specifications.

Are power steering and steering gear the same thing?
→ No. Power steering is the assistance system (hydraulic/electric), while the steering gear transmits the steering wheel movement to the wheels.

How much does a new steering gear cost?
→ Roughly $1,000–$2,500, depending on the vehicle.

What noises does a broken steering gear make?
→ Cracking, rattling, knocking when steering; often clearly audible at low speeds.

Conclusion – Acting in Good Time Saves Costs

A fully functional power steering system is essential. Recognizing symptoms early and having the cause professionally repaired prevents consequential damage and keeps you safe on the road. Especially with older vehicles, it is worth keeping a regular eye on the steering gear and power steering system – this pays off in terms of safety and your wallet.
