When Should Steering Components Be Replaced?

Steering components don’t always fail suddenly. In most cases, wear develops gradually, making it easy to miss until it starts affecting vehicle handling, tyre wear or MOT outcomes.

For workshops, knowing when steering components should be replaced is just as important as spotting faults.

When should steering components be replaced?

Steering components should be replaced when:

• Play exceeds manufacturer tolerances

• Protective boots are split or leaking

• Joints show signs of corrosion or contamination

• Movement is no longer smooth or consistent

• Wear is identified during inspection or MOT

Even if symptoms are minimal, worn components can quickly deteriorate and impact safety.

What happens if worn steering components are not replaced?

Failing to replace worn steering components can lead to:

• Loss of steering precision

• Increased stopping distances due to instability

• Accelerated tyre wear

• Additional strain on suspension components

• Potential MOT failure

In severe cases, excessive wear in components like tie rod ends can result in joint failure.

Key inspection points for steering components

1. Free play in joints

Check for excessive movement in tie rod ends and inner tie rods. Any noticeable play is a clear sign of wear.

2. Condition of dust boots

Split or damaged boots allow dirt and moisture into the joint, accelerating wear internally.

3. Corrosion and contamination

Rust or debris around joints can affect performance and longevity.

4. Smooth articulation

Components should move smoothly without stiffness or grinding.

5. Secure fitment

Loose or poorly seated components can mimic wear symptoms and should be addressed immediately.

Are steering components an MOT failure?

Yes - steering components are assessed during an MOT.

Issues that can lead to failure include:

• Excessive play in ball joints or tie rod ends

• Insecure mountings

• Damaged or deteriorated protective covers

• Steering rack issues affecting control

This makes regular inspection essential, particularly ahead of MOT testing.

How quickly do steering components wear once damaged?

Once contamination enters a steering joint (for example, through a split boot), wear can accelerate rapidly.

What may start as minor degradation can develop into:

• Noticeable play

• Noise during steering

• Reduced alignment stability

This is why early replacement is often more cost-effective than delaying repairs.
