Steering problems: pulling, shaking, heavy or vague steering
When a vibration or pull happens matters more than anything else. A shake that appears around motorway speed and fades above it is almost always wheel balance. A shake only when braking is usually the discs. A steady pull is alignment or a tyre, and heavy steering usually means the power steering.
Anything that affects the steering gets at least an amber verdict — get it checked within days.

Steering wheel shaking at speed
Drive carefully — book it in
You can drive gently, but get it looked at within days rather than weeks. Left alone it will get worse, less safe or more expensive.
Likely causes
- Wheel out of balanceMost likely
A vibration through the steering wheel at 50–70mph that fades above that speed — often after new tyres or a kerb strike.
If it's this: not urgent.
- Damaged or under-inflated tyreLikely
Check the pressures, and look for a bulge on the sidewall or a nail in the tread. A bulge means the tyre can fail — replace it before driving at speed.
If it's this: get it checked soon.
- Worn track rod endPossible
A knock through the steering wheel, and play when a front wheel is rocked side to side (hands at 3 and 9 o'clock) with the car jacked up.
If it's this: get it checked soon.
- Wheel alignment outPossible
The steering wheel sits off-centre on a straight road, and the front tyres wear on one edge.
If it's this: not urgent.
What to do next
Most often a wheel balance — cheap and quick at any tyre place. Check the tyres for a bulge first.
Steering wheel shaking when braking
Drive carefully — book it in
You can drive gently, but get it looked at within days rather than weeks. Left alone it will get worse, less safe or more expensive.
Likely causes
- Worn, corroded or warped brake discsMost likely
A pulsing pedal or a shaking steering wheel when braking, and a raised lip around the edge of the disc.
If it's this: get it checked soon.
- Sticking brake caliper or slider pinsPossible
The car pulls to one side, one wheel is much hotter than the others after a drive, and there's a burning smell.
If it's this: get it checked soon.
- Worn suspension arm bushesPossible
A clunk when braking or pulling away, and steering that wanders at speed.
If it's this: get it checked soon.
What to do next
Almost always the brake discs. Get them checked within days.
Car pulling to the left or right
Drive carefully — book it in
You can drive gently, but get it looked at within days rather than weeks. Left alone it will get worse, less safe or more expensive.
Likely causes
- Wheel alignment outMost likely
The steering wheel sits off-centre on a straight road, and the front tyres wear on one edge.
If it's this: not urgent.
- Damaged or under-inflated tyreLikely
Check the pressures, and look for a bulge on the sidewall or a nail in the tread. A bulge means the tyre can fail — replace it before driving at speed.

What to do next
Check the tyre pressures first — one soft tyre is the cheapest fix there is. If they're right, have the alignment checked.
Heavy steering
Drive carefully — book it in
You can drive gently, but get it looked at within days rather than weeks. Left alone it will get worse, less safe or more expensive.
Likely causes
- Power steering faultMost likely
Heavy steering with a steering warning light (electric), or a whine on full lock and a low fluid level (hydraulic).
If it's this: get it checked soon.
- Damaged or under-inflated tyreLikely
Check the pressures, and look for a bulge on the sidewall or a nail in the tread. A bulge means the tyre can fail — replace it before driving at speed.
If it's this: get it checked soon.
- Flat or failing 12V batteryLikely
The dash and interior lights are dim or die when you try to start. If a jump start fires it straight up, you've found it.
If it's this: not urgent.
What to do next
Check the front tyre pressures. If there's a steering warning light, the power assistance has failed — you can still steer, but it takes much more effort.
Vague steering or the car wandering
Drive carefully — book it in
You can drive gently, but get it looked at within days rather than weeks. Left alone it will get worse, less safe or more expensive.
Likely causes
- Worn suspension arm bushesMost likely
A clunk when braking or pulling away, and steering that wanders at speed.
If it's this: get it checked soon.
- Worn track rod endLikely
A knock through the steering wheel, and play when a front wheel is rocked side to side (hands at 3 and 9 o'clock) with the car jacked up.
If it's this: get it checked soon.
- Worn suspension ball jointLikely
A clunk over bumps or when braking, and play when a front wheel is rocked top to bottom (hands at 12 and 6 o'clock) with the car jacked up.
If it's this: get it checked soon.
- Wheel alignment outPossible
The steering wheel sits off-centre on a straight road, and the front tyres wear on one edge.
If it's this: not urgent.
What to do next
Worn steering and suspension joints get worse, not better. Have it checked within days — this is safety-critical.
A shortlist, not a diagnosis
The ranking is the one a mechanic would give over the counter for a typical car — nobody can road-test a car over the internet, and the real cause may not be listed. Add the registration in the checker above to have it checked against that car's MOT advisories, mileage and engine. Have the car checked by a qualified mechanic before relying on it, and if you're unsure whether it's safe, don't drive it.
Common questions
Why is my car pulling to one side?
Most often wheel alignment, or a tyre that's under-inflated or damaged — check the pressures first, it's free. Many roads also slope towards the kerb, which causes a slight pull on its own. If the pull only happens when braking, a sticking brake caliper is more likely.
Why does my steering wheel shake at motorway speed?
Nearly always a front wheel out of balance, often after a balance weight has fallen off, and a tyre centre can rebalance it quickly. If it shakes at all speeds, or only when braking, look at the tyres, the brake discs or the steering joints instead.
Is heavy steering dangerous?
It makes the car harder to control in an emergency, so get it checked within days. On electric power steering it often comes with a warning light; on a hydraulic system check the fluid level and listen for a whine on full lock.
