The Steering System: A Quick Look

Before diving into the specifics, let’s get a basic picture of how a car’s steering system works. The steering wheel is connected to the steering column. The steering column then links to the steering rack (or steering box in older vehicles). The steering rack translates the rotational motion of the steering wheel into linear motion, which pushes or pulls the tie rods. The tie rods, in turn, connect to the wheels and cause them to turn. In many modern cars, power steering assists this process.

Common Reasons Your Steering Wheel Isn’t Turning the Wheels

Several issues can break the connection between your steering wheel and your wheels. Here’s a list of possible culprits:

1. Broken Steering Linkage

The steering linkage refers to the different parts connecting the steering wheel to the wheels. A broken steering linkage is one of the most dangerous scenarios because it results in total loss of steering control.

Identifying a Broken Linkage

• Visual Inspection: Carefully inspect all parts under the car, paying close attention to joints and connections.
• Excessive Play: There will likely be a lot of free movement in the steering wheel without any corresponding movement in the wheels.
• Strange Noises: You might hear clunking or rattling sounds coming from under the car, particularly when turning the steering wheel.

Possible Causes and Fixes

• Corrosion/Rust: Over time, rust can weaken metal parts, leading to breakage. Repair: Replace the corroded parts.
• Impact Damage: Hitting a curb or pothole can damage the linkage. Repair: Replace the damaged parts.
• Loose Connections: Bolts or nuts can loosen over time. Repair: Tighten or replace loose fasteners.

2. Tie Rod Problems

Tie rod problems, including a bent or broken tie rod, will prevent the wheels from turning. Tie rods are critical components that connect the steering rack to the steering knuckles (which hold the wheel bearings).

Recognizing Tie Rod Issues

• Vibrations: You may feel vibrations in the steering wheel.
• Uneven Tire Wear: The tires might show unusual wear patterns.
• Misalignment: The car might pull to one side.
• Looseness: When the car is lifted, you can try to move the wheels by hand, and excessive play may be observed.

What Causes Tie Rod Failure?

• Wear and Tear: Tie rods are subject to constant stress and can wear out.
• Impact Damage: Hitting potholes or curbs can bend or break them.
• Corrosion: Rust weakens the tie rods over time.

Fixing Tie Rod Problems

• Replacement: Tie rod replacement is usually the only option. It’s a good idea to replace tie rods in pairs (both inner and outer) and get a wheel alignment afterward.

3. Steering Column Issues

Problems within the steering column issues can sever the connection between the steering wheel and the rest of the steering system. This can involve the collapse mechanism or internal components.

Diagnosing Steering Column Faults

• Stiffness: The steering wheel might be unusually hard to turn.
• Grinding Noises: You might hear grinding sounds coming from inside the column.
• Complete Lockup: The steering wheel might become completely locked.

Why Steering Columns Fail

• Wear and Tear: Internal components can wear out over time.
• Impact Damage: Accidents can damage the steering column.
• Faulty Components: Some components may fail prematurely due to manufacturing defects.

Solutions for Steering Column Problems

• Repair: Some problems, like loose connections, can be repaired.
• Replacement: More serious damage might require replacing the entire steering column.

4. Faulty Steering Rack

The faulty steering rack is at the heart of the steering system. If it fails, it cannot translate the steering wheel’s motion to the wheels.

Identifying a Bad Steering Rack

• Fluid Leaks: Look for power steering fluid leaks around the rack.
• Stiff Steering: The steering wheel might be difficult to turn.
• Play in the Steering Wheel: Excessive play can be observed.
• Noises: Hear unusual noises when turning the steering wheel.

Reasons for Steering Rack Failure

• Wear and Tear: Internal seals and components wear out.
• Fluid Contamination: Contaminated power steering fluid can damage the rack.
• Corrosion: Internal corrosion can cause the rack to fail.

Fixing a Faulty Steering Rack

• Replacement: In most cases, replacing the steering rack is the best solution.
• Rebuilding: Some shops offer steering rack rebuilding services.

5. Power Steering Failure

While power steering failure doesn’t usually cause a complete loss of steering, it can make the steering very difficult, potentially feeling like the wheels aren’t turning as much as they should.

Recognizing Power Steering Problems

• Hard Steering: The steering wheel is very hard to turn, especially at low speeds.
• Noises: A whining or squealing noise when turning the wheel.
• Low Fluid Level: The power steering fluid reservoir is low.

Causes of Power Steering Failure

• Low Fluid: A leak in the system causes low fluid levels.
• Faulty Pump: The power steering pump fails to generate enough pressure.
• Broken Belt: The belt that drives the power steering pump breaks.
• Hydraulic System Failure: Issues in the hydraulic system failure, such as blocked lines or a faulty valve.

Correcting Power Steering Issues

• Check Fluid Level: Refill the power steering fluid reservoir.
• Check for Leaks: Inspect the system for leaks and repair them.
• Replace Pump: Replace the power steering pump if it’s faulty.
• Replace Belt: Replace a broken or worn-out serpentine belt.

6. Worn Universal Joint

A worn universal joint (U-joint) on the steering shaft can cause a loss of steering. The U-joint connects sections of the steering shaft and allows it to operate at an angle.

Symptoms of a Worn U-Joint

• Stiff Steering: The steering might feel tight or binding.
• Play in the Steering Wheel: You might notice excessive play.
• Noises: Clunking or clicking sounds when turning the wheel.

Causes of U-Joint Problems

• Wear and Tear: U-joints wear out over time due to lack of lubrication and constant movement.
• Corrosion: Rust can cause them to seize.

U-Joint Fixes

• Replacement: U-joints are typically replaced rather than repaired.

7. Steering Shaft Damage

Steering shaft damage can be a severe issue that disconnects the steering wheel from the steering mechanism. This is critical because the steering shaft physically transmits your steering input to the steering gear.

Recognizing Steering Shaft Problems

• Complete Loss of Steering: The most alarming sign is when the steering wheel turns with no response from the wheels.
• Unusual Noises: Grinding, clicking, or popping sounds can indicate damage within the shaft itself.
• Vibration in Steering Wheel: Excessive vibration, especially during turns, can suggest a compromised shaft.
• Difficulty Steering: In some cases, you might experience a noticeable increase in the effort required to turn the wheel.

Common Causes of Steering Shaft Issues

• Accident or Impact: A collision, even a minor one, can bend or fracture the steering shaft.
• Corrosion: Rust, particularly in older vehicles, can weaken the metal of the shaft over time.
• Wear and Tear: Constant use and stress can lead to the gradual degradation of the shaft’s components.
• Loose Connections: Sometimes the bolts connecting sections of the shaft can loosen, creating play and potentially leading to failure.

Solutions for Steering Shaft Damage

• Replacement is Recommended: Due to the critical nature of the steering shaft, replacement is often the safest and most reliable solution.
• Professional Inspection: An experienced mechanic should thoroughly inspect the shaft to determine the extent of the damage.
• Check Compatibility: Ensure the replacement shaft is the correct one for your vehicle’s make and model.

8. Disconnected Steering Mechanism

A disconnected steering mechanism is a general term describing any break in the connection between the steering wheel and the wheels that isn’t pinpointed to a specific part. This can range from a sheared bolt to a completely separated joint.

Identifying a Disconnected Mechanism

• Complete Loss of Steering: Turning the wheel produces no response at the wheels.
• Visible Separation: A careful inspection might reveal a joint or connection that has come apart.
• Loud Noises: A sudden snap, pop, or clunk might have accompanied the disconnection.

Reasons for Disconnection

• Failed Fasteners: Bolts, nuts, or other fasteners can break or loosen.
• Sheared Parts: Metal parts can shear under stress.
• Corrosion: Rust can weaken connections.

Addressing a Disconnected Steering Mechanism

• Immediate Inspection: Do not drive the vehicle! Have it towed to a mechanic.
• Thorough Repair: All damaged or worn parts must be replaced.
• Professional Diagnosis: A skilled mechanic can pinpoint the exact cause and ensure a proper repair.

9. Steering Gear Malfunction

Steering gear malfunction refers to issues within the steering box (in older vehicles) or the steering rack (in newer vehicles) that prevent it from properly translating the steering wheel’s motion.

Symptoms of Steering Gear Issues

• Excessive Play: A lot of movement in the steering wheel before the wheels respond.
• Stiff Steering: Difficulty turning the wheel.
• Wandering: The car drifts from side to side.
• Noises: Grinding or clicking sounds.

Causes of Steering Gear Problems

• Wear and Tear: Internal components wear out over time.
• Lack of Lubrication: Insufficient lubrication can cause parts to bind.
• Fluid Contamination: Contaminated power steering fluid can damage the gear.

Fixing Steering Gear Problems

• Adjustment: Minor problems can sometimes be solved with adjustments.
• Rebuilding: The steering gear can be rebuilt by a specialist.
• Replacement: Replacing the steering gear is often the best solution.

Troubleshooting Steps

Here’s a basic process for diagnosing the “steering wheel turns but wheels don’t” issue:

1. Visual Inspection: Check all visible steering components for damage, looseness, or corrosion. This includes tie rods, linkages, and the steering shaft.
2. Fluid Check: Verify the power steering fluid level and look for leaks.
3. Steering Wheel Play: Check for excessive play in the steering wheel before the wheels start to turn.
4. Listen for Noises: Pay attention to any unusual sounds when turning the steering wheel.
