A clicking noise when turning can have several causes, but the pattern of the sound often gives an important clue. A rapid clicking that gets faster as the wheels rotate can point towards a worn CV joint, while a heavier clunk may come from a ball joint, tie rod end or another suspension component.
The important thing is not to ignore a new clicking or knocking noise. Some causes are relatively minor, while others can affect steering, suspension or the drivetrain if the underlying fault continues to worsen. Paying attention to when the noise occurs, whether you are turning left or right, and whether it also happens over bumps can help narrow down the possible cause.
For drivers in Aldershot, Farnborough and Fleet, this guide explains the most common reasons a car makes a clicking noise when turning. Ash Road Service Centre can also help investigate persistent steering, suspension and drivetrain noises.
The Most Common Causes
1. A Worn CV Joint
This is by far the most frequent cause of a clicking noise when turning, particularly on front-wheel-drive vehicles. CV joints are flexible couplings that connect the driveshafts to the front wheels, allowing power to be delivered while the wheels steer left and right. Each front wheel has an inner and outer CV joint. The outer joint is the one most commonly responsible for the clicking.
The joint is packed with grease and protected by a rubber boot. When that boot cracks or tears, grease escapes and road grit enters. The contamination accelerates wear on the internal ball bearings, which begin to skip and click through their channels during turns rather than rolling smoothly.
The sound is a rapid, rhythmic clicking or popping that increases in speed with the wheel’s rotation. It is most obvious during sharp turns at low speed, such as parking or slow junctions, and may disappear almost entirely during straight-line driving. One side is often worse than the other depending on which joint is affected.
The progression follows a clear pattern:
- Faint click on tight turns only: boot compromised, grease escaping
- Louder clicking on moderate turns: internal wear established
- Clicking during straight-line driving or acceleration: joint in advanced deterioration
A failed CV joint can leave the wheel without drive power or cause the axle to break entirely. Once clicking begins, the joint needs professional assessment promptly. It will not improve on its own.
| CV Joint Fault Stage | When Clicking Occurs | Urgency |
| Early: boot cracked, grease escaping | Faint click on very tight turns only | Book inspection promptly |
| Mid: joint contaminated, wear developing | Clear clicking during moderate turns | Book within days, not weeks |
| Advanced: significant internal wear | Loud clicking, both directions affected | Inspect immediately |
| Severe: joint near failure | Clicking during straight-line driving | Do not delay, safety risk |
2. Worn Ball Joints
Ball joints are the pivot points that connect the suspension control arms to the steering knuckle at each front wheel. They allow the wheel assembly to move up and down with the suspension while simultaneously pivoting left and right for steering. A ball joint is essentially a ball-and-socket mechanism enclosed in a housing and protected by a rubber boot.
As ball joints wear, they develop play in the joint housing. This looseness allows the ball to move slightly within the socket under load, producing a clicking or clunking sound when the suspension is loaded and unloaded by steering inputs, bumps, or acceleration. The sound from a worn ball joint tends to be slightly heavier and less rapid than a CV joint click, more of a distinct clunk than a rhythmic tick, and it often appears over bumps as well as during turns.
This is the key diagnostic difference between a ball joint and a CV joint. A worn CV joint clicks specifically and consistently during turns, with the frequency matching the wheel’s rotation speed. A worn ball joint tends to produce a single clunk or click during a turn, particularly as the load shifts through the joint, and will often also make a noise when the car travels over a pothole, speed bump, or uneven surface.
Ball joints are safety-critical components. They maintain the precise geometric relationship between the wheel and the suspension that makes steering predictable and stable. A ball joint that has developed significant play can allow the wheel to shift slightly during cornering or braking, affecting handling in ways the driver may not immediately recognise. In the most severe cases, a fully failed ball joint can separate from the knuckle under load, causing a sudden and complete loss of steering control. Any suspected ball joint fault should be inspected by a professional without delay.
3. Worn or Loose Tie Rod Ends
Tie rod ends are the components that transmit the movement of the steering rack to the wheel hubs, translating rotation of the steering wheel into left and right movement of the front wheels. Each tie rod end contains its own small ball-and-socket joint, similar in principle to the ball joints in the suspension, and is similarly protected by a rubber boot.
When tie rod ends wear, they develop play at the joint. This looseness allows a small amount of unwanted movement within the steering linkage during direction changes, which produces a clicking or knocking sound most noticeable during slow, tight manoeuvres. The sound tends to accompany a subtle change in how the steering feels: a slight vagueness or a small amount of slack in the wheel before the car responds to a steering input.
Uneven tyre wear, particularly on the inner or outer edge of the front tyres, can also indicate a worn tie rod end, as any looseness in the steering linkage affects the tracking and alignment of the front wheels. After tie rod end replacement, a wheel alignment check is always necessary, as the position of the rod end directly determines the car’s tracking geometry.
4. Worn or Dry Suspension Bushes
Control arm bushings are rubber inserts that cushion the connection between the control arm and the vehicle’s subframe. They absorb vibration and allow the controlled movement the suspension needs during cornering. On UK roads, with their combination of speed bumps, potholes, and winter road salt, bushing wear is one of the more common findings during any suspension inspection.
As the rubber ages it hardens, cracks, and loses its dampening ability. When a bushing binds and releases against its mounting point during a turn, it produces a squeaking, clicking, or creaking sound from the underside of the car. The noise tends to be worse on cold mornings when rubber is at its stiffest, and is usually accompanied by a general increase in harshness over rough surfaces.
| Bushing Condition | Sound | Other Signs |
| Early wear | Faint creak on sharp turns | Slight increase in road noise |
| Moderate wear | Consistent clicking or creaking | More harshness, mild handling vagueness |
| Advanced deterioration | Louder knock during turns and over bumps | Uneven tyre wear, poor handling |
5. A Worn or Dry Strut Mount or Top Bearing
The strut mount connects the top of each front suspension strut to the vehicle’s body. Inside it sits a bearing that allows the strut to rotate smoothly as the steering wheel is turned. When this bearing wears out or corrodes, it produces a clicking, popping, or grating sound with every steering input.
The most useful diagnostic feature here is that the sound can often be reproduced with the car completely stationary. Turn the steering wheel slowly from side to side with the engine running and listen for a click or pop from the top of the wheel arch. A worn CV joint requires the wheel to be rotating under load to produce its sound. A strut mount bearing does not, which makes this a straightforward distinction.
| Fault | Stationary Steering Test | Moving Slowly | Over Bumps |
| Worn CV joint | Silent | Rapid rhythmic clicking on turns | Usually silent |
| Worn strut mount bearing | Distinct click or pop | Click with each steering input | Can produce a thud |
| Worn ball joint | Usually silent | Clunk during turns | Clunk or knock |
| Worn bushings | Occasional creak | Creaking or clicking | Harshness and creak |
Strut mount wear is more common on higher-mileage vehicles and accelerates on cars regularly exposed to road salt through winter, which is a familiar reality for drivers across Hampshire.
6. Low or Contaminated Power Steering Fluid
On vehicles with hydraulic power steering, the system uses pressurised fluid to make steering effort light and responsive. When fluid levels drop due to a slow leak, or when the fluid has degraded through age, the pump struggles to maintain the pressure needed during a full steering input.
The sound is usually a groaning or whining from the pump, though in some cases it presents as a clicking or rattling from the steering rack area during turns. It is almost always accompanied by noticeably heavier steering effort, which is the clearest sign that the power steering system rather than the wheel end is involved. If the reservoir is low, the fluid has gone somewhere. Topping it up without finding the source of the leak only delays the problem.
| Power Steering Type | Fluid Involved | Clicking Cause |
| Hydraulic | Yes | Low or degraded fluid starves pump under full lock |
| Electric | No | Clicking is mechanical, at wheel end components |
| Electro-hydraulic | Yes, electrically driven pump | Low fluid can still affect pressure and produce noise |
Many vehicles produced in the last ten to fifteen years use electric power steering with no fluid at all. On these cars, a clicking noise during turns will be mechanical in origin, and the diagnosis should focus on CV joints, ball joints, tie rod ends, and strut mounts from the outset.
7. A Loose or Broken Anti-Roll Bar Drop Link
The anti-roll bar, also known as a stabiliser bar, connects the suspension on each side of the axle and reduces body roll during cornering. Drop links are the short connecting rods that link the anti-roll bar to the suspension strut on each side. They contain small ball joints at each end that allow the link to pivot as the suspension moves.
When a drop link becomes worn, corroded, or breaks, the anti-roll bar loses its connection to the suspension on that side. This creates a knocking or clicking sound that often occurs over bumps as well as during turns. The sound from a broken drop link is frequently described as a hollow, rattling knock that seems to come from low down in the suspension, and may be accompanied by increased body roll during cornering.
Drop links are one of the more common suspension faults on UK vehicles, partly because they are exposed to road spray, salt, and debris throughout their service life.
How to Tell the Causes Apart
The location, character, and circumstances of the clicking sound are the most useful diagnostic information before the car goes on a ramp.
| Noise Character | When It Occurs | Most Likely Cause |
| Rapid, rhythmic clicking matching wheel speed | Sharp turns at low speed, disappears straight-line | Outer CV joint worn |
| Single clunk during turn, also over bumps | Cornering and uneven surfaces | Ball joint or drop link |
| Click or knock during slow parking turns | Very slow manoeuvres, may feel through wheel | Tie rod end or strut mount bearing |
| Creaking or dry click from underneath | Cornering, worse when cold | Control arm bushings |
| Groaning or clicking under full steering lock | Slow speed, heavier steering feel | Power steering fluid or pump |
| Hollow rattle, both cornering and over bumps | All conditions, louder over rough roads | Broken or worn drop link |
Can You Drive with a Clicking Noise When Turning?
The answer depends entirely on which component is causing the noise and how advanced the fault is.
An early-stage CV joint clicking only on the tightest turns is generally manageable for short journeys while an inspection is arranged. However, the situation is not static. CV joints do not improve, and the window between the first noticeable click and complete joint failure can be shorter than many drivers expect, particularly in cold and wet conditions where the joint is exposed to additional stress.
Ball joint and tie rod end faults require more urgent attention. Both are safety-critical steering and suspension components. Play in either one affects the car’s handling and, in advanced stages, creates a genuine risk of sudden failure under load. Any suspected ball joint or tie rod fault warrants immediate professional inspection rather than a monitored wait.
A broken drop link, while less immediately dangerous than a ball joint fault, should still be addressed promptly as it affects the stability of the suspension and increases the forces acting on surrounding components during cornering.
The golden rule is that any new noise from the front of the car, particularly one that appears specifically during steering inputs, deserves professional attention quickly. Noises from suspension and drivetrain components are the car’s way of signalling wear that is already established and is continuing to progress with every mile driven.
What Happens During a Professional Inspection
When a car is brought in with a clicking noise during turns, a thorough inspection covers the full range of components that could be responsible rather than replacing parts on the basis of the most likely cause alone.
The technician will carry out a visual inspection under the vehicle with the wheels turned to full lock on each side, checking the CV boots for splits, tears, or evidence of grease ejection such as a dark, greasy spray on surrounding components. They will check ball joints and tie rod ends for play using a pry bar to load the joint and observe movement, and they will assess drop links, bushings, and strut mounts for signs of wear, corrosion, or failure. A road test will confirm which conditions reproduce the sound and from which corner of the car it originates most clearly.
If the cause is not obvious from the initial inspection, car diagnostics can help narrow down whether the noise is coming from the drivetrain, steering or suspension.
This process ensures the correct component is identified and replaced rather than the most commonly assumed one. Several of the causes listed above produce sounds that overlap in character, and accurate diagnosis under controlled conditions is what separates a targeted repair from an expensive process of elimination.
A fault in any of these components can result in a major defect and an automatic failure, making it far more cost-effective to address a known issue before test day than to discover it through a failed certificate.
Conclusion
A clicking noise when turning is one of the clearest diagnostic signals a car can produce. It is precise in its conditions, consistent in its character, and directly traceable to a small number of well-understood components. That specificity is genuinely useful: it gives both the driver and the technician a clear starting point rather than a vague symptom requiring extensive elimination.
The outer CV joint accounts for the majority of cases, particularly on front-wheel-drive vehicles used for frequent low-speed urban driving. But ball joints, tie rod ends, drop links, bushings, strut mount bearings, and power steering issues all follow recognisable patterns that distinguish them from one another when the noise is described accurately.
What all of these causes share is the same fundamental truth: the noise will not resolve itself. Each of these components continues to wear with every mile driven and every turn made. Catching the fault early keeps the repair simple and the cost manageable. Leaving it means driving on components that are deteriorating toward failure, and in several cases that failure has direct consequences for steering control and safety.
If your car has started clicking when you turn, the right move is to book an inspection and let the evidence under the car tell the full story.
If your car has started clicking when you turn, the right move is to arrange an inspection rather than trying to diagnose the noise by sound alone. If you need a local workshop, you can also get directions to Ash Road Service Centre on Google.
Frequently Asked Questions
What is the most common cause of a clicking noise when turning?
A worn outer CV joint is the most frequent cause, particularly on front-wheel-drive vehicles. The rubber boot surrounding the joint splits or cracks over time, allowing grease to escape and debris to enter. The resulting wear on the joint’s internal ball bearings produces a rapid clicking or popping sound that is most pronounced during sharp turns at low speed.
Does the clicking being worse on one side tell me anything?
Yes. If the clicking is clearly louder when turning in one direction than the other, the fault is almost certainly on the side that is under greater load during that turn. For a CV joint, turning right loads the left-hand joint more and vice versa. This can help a technician narrow down which side needs attention before the vehicle is even put on a ramp.
Can I keep driving with a clicking CV joint?
In its very earliest stages, a clicking CV joint may allow short, careful journeys while an inspection is arranged. However, the joint does not repair itself and will continue to deteriorate. A joint that clicks only on tight turns today can develop to clicking during moderate turns within weeks, and in advanced stages, complete joint failure can leave the car immobile or create a safety hazard. Acting promptly is always the right approach.
How do I tell the difference between a CV joint and a ball joint noise?
A CV joint click is rapid and rhythmic, matching the rotational speed of the wheel, and occurs specifically during turns. A ball joint clunk tends to be a single, heavier sound per steering or suspension input and typically also occurs when the car travels over bumps or uneven road surfaces, not only when turning.
Will a clicking noise when turning fail an MOT?
A clicking noise itself is not a pass or fail criterion, but the underlying cause almost certainly is. Worn CV joints, ball joints, and tie rod ends with measurable play are major defects under MOT testing guidelines. A technician carrying out an MOT will check these components physically, and any that show excessive play or visible damage will result in a failure regardless of whether a noise is present.
Can a clicking noise when turning be something minor?
Occasionally, a loose heat shield near the exhaust or a stone trapped in a brake dust cover can produce a sound during turns that resembles a more serious fault. However, these causes produce a less consistent, often more random sound than the rhythmic click of a worn CV joint or the distinct clunk of a worn ball joint. Any clicking that occurs consistently with turning inputs deserves a professional inspection to confirm the cause, whether minor or otherwise.
