You're driving along a reasonably straight road and the vehicle seems to drift left or right.
You find yourself constantly applying a little steering pressure to keep it straight.
Perhaps the steering wheel is sitting slightly off-centre.
Or maybe the vehicle only pulls when you brake.
A common reaction is:
“I NEED A WHEEL ALIGNMENT.”
Maybe.
But not necessarily.
A vehicle can pull to one side because of problems involving the:
- Tyres
- Tyre pressures
- Wheel alignment
- Steering
- Suspension
- Brakes
- Vehicle geometry
- Road surface
At The Cape Brake Co, we don't perform wheel alignment in-house, but we do diagnose and repair steering and suspension problems that can cause pulling or prevent an alignment from being carried out properly.
And that's an important distinction.
WHAT DOES IT MEAN WHEN A CAR “PULLS”?
A genuine pull means the vehicle consistently tends to steer or move toward one side rather than tracking straight ahead.
You may notice that:
- You need constant steering correction
- The steering wheel wants to move toward one side
- The vehicle drifts relatively quickly when steering input is relaxed
- One direction requires more steering effort than the other
But before assuming something is wrong, we also need to consider the road itself.
CAN ROAD CAMBER MAKE MY CAR PULL?
Yes.
Roads aren't normally perfectly flat from left to right.
They're often built with a slight slope, or camber, to allow rainwater to drain toward the side of the road.
That can cause a vehicle to naturally drift slightly toward the lower side.
The effect varies depending on:
- Road design
- Tyres
- Suspension geometry
- Vehicle type
- Steering characteristics
So a slight tendency to follow the road camber isn't necessarily a fault.
A strong or persistent pull across different roads deserves more investigation.
CAN TYRE PRESSURE MAKE MY CAR PULL?
Yes.
Unequal tyre pressures can affect how the vehicle behaves.
If one tyre is significantly underinflated compared with the tyre on the opposite side, rolling resistance and tyre behaviour can differ.
Before investigating something complicated, one of the simplest checks is therefore:
ARE THE TYRES CORRECTLY INFLATED?
And not simply:
“THEY LOOK FINE.”
Modern tyres can be surprisingly difficult to judge visually.
CAN THE TYRES THEMSELVES CAUSE A PULL?
Absolutely.
Tyres aren't perfectly identical just because they're the same size.
Pulling can potentially be influenced by:
- Uneven tyre wear
- Tyre construction
- Internal tyre damage
- Different tyre models
- Different tread depths
- Incorrect tyre fitment
- Tyre deformation
Sometimes changing the position of tyres during diagnosis can provide useful information about whether the pull follows a particular tyre.
That doesn't mean every pull is a tyre problem.
But tyres should be part of the investigation.
DOES MY CAR NEED A WHEEL ALIGNMENT?
Possibly.
Wheel alignment refers to the geometric angles at which the wheels sit relative to the vehicle and road.
Depending on the suspension design, alignment measurements can include:
TOE
The direction the wheels point relative to each other when viewed from above.
CAMBER
The inward or outward inclination of the wheel when viewed from the front.
CASTER
An angle relating to the steering axis that influences steering behaviour and self-centring.
Not every angle is adjustable on every vehicle.
And importantly:
ALIGNMENT SETTINGS CAN'T COMPENSATE FOR WORN-OUT SUSPENSION PARTS.
WHY SHOULD SUSPENSION BE CHECKED BEFORE ALIGNMENT?
Imagine a control-arm bush or ball joint has excessive play.
The wheel may be capable of moving away from its intended position as the vehicle drives.
You can place that vehicle on an alignment machine and adjust the geometry, but if worn components allow the wheel to move afterwards, the alignment may not remain where it should.
That's why steering and suspension condition matters.
If there is excessive play in components such as:
- Control-arm bushes
- Ball joints
- Tie rod ends
- Inner steering joints
- Wheel bearings
- Other suspension joints
those issues may need attention before alignment.
DOES CBC DO WHEEL ALIGNMENT?
No.
The Cape Brake Co does not perform wheel alignment in-house.
What we can do is inspect and repair the mechanical steering and suspension components that influence wheel control and geometry.
So if your vehicle has:
- Worn bushes
- Worn ball joints
- Steering play
- Damaged suspension components
- Other mechanical faults
we can address those first.
Once the vehicle is mechanically sound, wheel alignment can then be performed by an alignment specialist where required.
That prevents you from paying for an alignment only to discover that worn components need replacing afterwards.
CAN A WORN CONTROL-ARM BUSH MAKE THE CAR PULL?
Potentially.
Control-arm bushes help locate the wheel and suspension while allowing controlled movement.
If a bush has deteriorated significantly, the arm may move more than intended as forces act on the wheel.
That movement can affect:
- Wheel position
- Steering behaviour
- Braking stability
- Tyre wear
- Alignment geometry
The symptoms depend on the suspension design and which bush is affected.
CAN A BALL JOINT CAUSE STEERING PROBLEMS?
Yes.
Ball joints form important pivot points in many suspension systems.
Excessive wear can allow unwanted movement.
Depending on the design and severity, that can contribute to:
- Steering looseness
- Knocking
- Abnormal tyre wear
- Changes in handling
- Poor wheel control
A badly worn ball joint is more than an alignment problem.
It's a mechanical and potentially safety-critical problem.
CAN TIE ROD ENDS AFFECT ALIGNMENT?
Absolutely.
Tie rods form part of the steering linkage and control the direction in which the wheels point.
On many vehicles, adjustment of the tie rods is actually how toe alignment is set.
If a tie rod end or inner steering joint has excessive play, accurate wheel control becomes difficult.
That's why steering joints should be sound before alignment is finalised.
WHY DOES MY CAR PULL WHEN I BRAKE?
This is particularly important because it may not be an alignment problem at all.
If the vehicle tracks reasonably straight during normal driving but pulls strongly when the brakes are applied, we need to consider the braking system.
Possible causes can involve:
- Uneven braking force
- Brake caliper problems
- Hydraulic issues
- Contamination
- Brake component condition
Suspension movement can also become more noticeable under braking because weight transfers toward the front of the vehicle.
So:
PULLS ALL THE TIME
and
PULLS ONLY WHEN BRAKING
are two very different clues.
Brake-related pulling falls naturally into CBC's specialist brake diagnostics.
WHY DOES MY CAR PULL WHEN I ACCELERATE?
Again, the timing matters.
A vehicle that changes direction under acceleration may require investigation of:
- Suspension bushes
- Engine or gearbox mountings
- Driveshafts
- CV joints
- Drivetrain behaviour
- Tyres
- Vehicle-specific suspension geometry
Powerful front-wheel-drive vehicles can also exhibit some degree of torque steer, depending on their design and road conditions.
The point is that acceleration-related pulling isn't automatically solved by wheel alignment.
WHY IS MY STEERING WHEEL CROOKED WHEN I'M DRIVING STRAIGHT?
An off-centre steering wheel can be associated with wheel alignment.
But there are other possibilities too.
It may occur after:
- Alignment work
- Suspension repairs
- Steering repairs
- Pothole impact
- Kerb impact
- Component replacement
If the car tracks straight but the steering wheel isn't centred, tell the alignment technician.
If the steering wheel has suddenly changed position, especially after an impact, we'd recommend having the steering and suspension checked.
CAN A POTHOLE MAKE MY CAR PULL?
Yes.
A significant pothole or kerb impact can potentially:
- Affect alignment
- Damage a tyre
- Bend a wheel
- Damage suspension components
- Affect steering components
If the vehicle drove straight before the impact and immediately began pulling afterwards, that's very useful history.
Don't simply realign the vehicle without checking for damage if the impact was substantial.
CAN RIDE HEIGHT AFFECT ALIGNMENT?
Yes.
Suspension geometry changes as the suspension moves through its travel.
If a vehicle sits abnormally low on one corner because of something such as a damaged spring, geometry can be affected.
Modified vehicles are another consideration.
Changes such as:
- Lift kits
- Lowering springs
- Different control arms
- Suspension spacers
- Larger wheels and tyres
can alter steering and suspension geometry.
If the suspension isn't standard, tell us.
WHAT ABOUT BAKKIES AND 4X4S?
The same basic principles apply, but these vehicles may experience additional factors such as:
- Heavy loads
- Towing
- Off-road use
- Suspension lifts
- Larger tyres
- Aftermarket suspension
- Regular gravel-road use
Load can change how a vehicle sits and behaves.
A bakkie carrying significant weight may therefore feel different from the same vehicle when unloaded.
If the pulling only occurs when towing or carrying a load, that's important information.
WHY ARE MY TYRES WEARING ON ONE EDGE?
Wheel alignment is one possible cause.
But uneven tyre wear can also be influenced by:
- Tyre pressure
- Worn suspension
- Worn shocks
- Steering play
- Driving conditions
- Vehicle loading
- Tyre condition
Read our guide, Why Are My Tyres Wearing Unevenly?, for more about what tyre-wear patterns can reveal.
For now, the important point is:
UNEVEN TYRE WEAR IS EVIDENCE.
Don't ignore it.
Your tyres can tell us a lot about how the vehicle has been behaving.
WILL AN ALIGNMENT FIX UNEVEN TYRE WEAR?
Correct alignment can prevent certain alignment-related wear from continuing.
But it can't restore tread that has already worn away.
And if the wear was caused by a worn mechanical component, alignment alone won't fix the underlying cause.
That's why we want the order to be:
INSPECT → REPAIR WORN COMPONENTS → ALIGN IF REQUIRED
rather than:
ALIGN → DISCOVER WORN PARTS → REPAIR → PAY FOR ALIGNMENT AGAIN.
DOES EVERY SUSPENSION REPAIR REQUIRE ALIGNMENT?
Not necessarily.
It depends on:
- Which component was replaced
- Suspension design
- Whether an alignment adjustment was disturbed
- Manufacturer procedure
Some steering and suspension repairs should be followed by wheel alignment.
Others may not materially alter adjustable geometry.
We'll advise when alignment is appropriate after the work we've carried out.
IS IT SAFE TO DRIVE A CAR THAT PULLS?
That depends on the cause and severity.
A mild tendency caused by road camber isn't the same as a vehicle suddenly pulling because of a mechanical or braking problem.
Have it checked promptly if:
- The pull appeared suddenly
- The vehicle is difficult to control
- Steering feels loose
- It pulls strongly when braking
- You recently hit a pothole or kerb
- A tyre appears damaged
- There are knocking or clunking noises
- Tyres are wearing rapidly or severely
- The steering wheel has suddenly changed position
Steering, suspension, brakes and tyres all affect your ability to control the vehicle.
WHAT SHOULD I TELL CBC?
If your vehicle is pulling, tell us:
- Make
- Model
- Year
- VIN
- Approximate mileage
- Which direction it pulls
- Whether it happens continuously
- Whether it happens under braking
- Whether it happens under acceleration
- Whether road speed changes it
- Whether the steering wheel is centred
- Whether you've recently hit a pothole or kerb
- Whether tyres have recently been changed
- Whether an alignment was recently performed
- Whether suspension or steering work was recently carried out
- Whether the suspension has been modified
- Whether you've noticed uneven tyre wear
Those details help us distinguish between an alignment complaint and a mechanical fault.
THE CBC APPROACH TO A CAR THAT PULLS
At The Cape Brake Co, we don't automatically treat:
CAR PULLS = WHEEL ALIGNMENT.
Instead, we ask:
ARE THE TYRES AND PRESSURES CORRECT?
IS THERE PLAY IN THE STEERING?
ARE THE SUSPENSION COMPONENTS SOUND?
DOES IT PULL ONLY UNDER BRAKING?
HAS SOMETHING BEEN DAMAGED?
IS THE VEHICLE MECHANICALLY READY FOR ALIGNMENT?
If the steering and suspension need repair, we deal with those components first.
Then, where alignment is required, the vehicle can go to an alignment specialist with a mechanically sound suspension underneath it.
DOES YOUR CAR KEEP PULLING LEFT OR RIGHT?
If your vehicle won't track straight, the steering wheel has moved off-centre or the vehicle has started behaving differently after a pothole or suspension repair, contact The Cape Brake Co.
We'll help establish whether you're dealing with a steering or suspension problem, a brake-related issue, or whether the vehicle simply needs to move on to an alignment specialist.
Ask the Workshop Assistant or WhatsApp The Cape Brake Co.
