Steering Components | What They Do, Types & When to Replace

AZ Motor Factors supplies a wide range of steering components for cars and vans, including tie rods/track rods, track rod ends, steering racks, power steering parts, and related bushes and joints. Steering parts must match your exact vehicle (model, engine, trim and year), so always confirm fitment details before ordering.

Common steering components (quick guide)

• Track rod ends (outer tie rods): Connect the steering to the wheel hub and allow adjustment of toe alignment.
• Inner tie rods (rack ends): Link the steering rack to the outer track rod end.
• Steering rack: Converts steering wheel input into left/right movement at the wheels (manual or power assisted).
• Rack gaiters/boots: Protect inner joints from dirt and water—important for long joint life.
• Steering column joints (U-joints): Allow smooth movement between the steering wheel and rack.
• Power steering pump / reservoir / hoses: Provide hydraulic assistance on older systems.
• Electric power steering (EPS) parts: Motors/sensors/modules used on modern systems (vehicle-specific).
• Steering knuckle & related joints: Work with suspension to support the wheel and enable steering movement.

When should you replace steering components?

There isn’t a fixed mileage for steering parts—wear depends on road conditions, potholes, kerb strikes, vehicle weight, and driving style. Many components start showing wear anywhere from 40,000–100,000 miles, but inspection and symptoms are the real trigger for replacement.

• Knocking/clunking when turning, over bumps, or during low-speed manoeuvres.
• Vague steering, excessive play in the wheel, or wandering on the motorway.
• Uneven tyre wear (often a sign of alignment issues caused by worn tie rods/ends).
• Steering wheel off-centre after straightening up, or the car pulling to one side.
• Vibration through the steering wheel, especially under braking or at speed (can also be wheels/tyres).
• Stiff or notchy steering, especially in one direction (possible rack/column joint issues).
• Power steering fluid leaks (wet hoses, pump noise, or low fluid level on hydraulic systems).
• Groaning/whining when turning (often pump, fluid, or air in hydraulic systems).
• Torn rack boots (lets water/dirt into inner joints—replace boots and inspect the joint).

Best practice (safety + handling)

• After replacing steering parts, get a professional wheel alignment to protect tyres and restore handling.
• Always replace worn parts in pairs where appropriate (e.g., left/right track rod ends) for consistent steering feel.
• Inspect related components (suspension bushes, ball joints, wheel bearings) if symptoms persist.

Tip: If you’ve hit a pothole or kerb and steering feels different afterwards, check alignment and components promptly—small issues can quickly lead to tyre wear and unsafe handling.
