Suspension bushes are the rubber or polyurethane components that allow the suspension arms, anti-roll bars and other components to move while cushioning the metal-to-metal contact points. Over time, bushes wear, crack and compress, affecting handling, ride quality and steering response. In 2026, understanding when bushes need replacing, the choice between rubber and polyurethane and the costs involved helps you maintain your car's handling and ride quality.
What Are Suspension Bushes?
Suspension bushes are mounted at the pivot points of the suspension — where control arms, anti-roll bar links, subframe mountings and other components attach to the car's body or subframe. They allow controlled movement while absorbing road shocks and reducing vibration and noise. Without bushes, every road imperfection would transmit directly into the body, creating a harsh ride and accelerating wear on all suspension components.
Symptoms of Worn Suspension Bushes
Clunking Noises
A metallic clunk or knocking noise — particularly over bumps, when turning or when braking — is a classic sign of worn suspension bushes. The noise occurs when the metal components move beyond the worn bush's range of movement.
Poor Handling and Vague Steering
Worn bushes — particularly on the front suspension — allow suspension components to move more than intended, making the steering feel vague and imprecise. The car may wander at speed and feel less responsive to steering inputs.

Uneven Tyre Wear
Worn suspension bushes change the geometry of the suspension, which can cause uneven tyre wear. If you notice unusual wear patterns on your tyres, have the suspension checked.
Visual Inspection
Some bushes are visible from under the car. Cracked, split or compressed-looking rubber bushes should be replaced. Polyurethane bushes should show no cracks or splits and should be lubricated with the correct lubricant.
Rubber vs Polyurethane Bushes
Rubber Bushes
- Standard factory specification on most vehicles
- Comfortable and effective at absorbing vibration
- Durable for normal road use
- Wears out over time — typically 80,000 to 150,000 miles
- Less precise handling than polyurethane
Polyurethane Bushes
- Upgraded performance alternative
- Significantly harder than rubber — improves handling precision
- Longer lasting — typically outlasts the car
- Transmits more vibration and noise into the cabin
- Requires regular lubrication with a silicone-based lubricant
- Can make the ride harsher on poor road surfaces
Suspension Bush Replacement Cost 2026
- Individual bush replacement: GBP 10 to GBP 40 per bush for parts
- Full front suspension bush kit: GBP 80 to GBP 300 for parts
- Labour per bush: GBP 40 to GBP 120 depending on accessibility
- Full front suspension refresh: GBP 400 to GBP 1,200 total

Frequently Asked Questions
Q: How much is car tax (VED) in the UK 2026?
Car tax rates in the UK depend on your vehicle's CO2 emissions and list price. Standard rates start from £190 per year for petrol and diesel cars, with zero-rated VED for EVs. First-year rates vary from £0 to £2,605 depending on emissions. Additional premiums apply for vehicles over £40,000.
Q: How do I check if my car is taxed online?
You can check your vehicle's tax status for free on the Gov.uk website at gov.uk/check-vehicle-tax. You'll need your vehicle's registration number (number plate). You can also check via the Motor Insurance Database to verify road tax and insurance status simultaneously.
Q: Can I get a refund on car tax if I sell my vehicle?
Yes — if you sell or scrap your vehicle, you can claim a refund on any full months of remaining road tax. Contact DVLA with the V11 reminder letter or apply online at gov.uk. Refunds are usually processed within 4-6 weeks.
Q: Is road tax refund available when transferring ownership?
No — road tax does not transfer with the vehicle. When you sell your car, the tax is automatically cancelled and any remaining months are refunded to you by DVLA. The new owner must tax the vehicle immediately. As a buyer, always verify the vehicle's tax status before purchasing.
Q: What is the luxury car tax threshold in the UK 2026?
The additional rate for vehicles over £40,000 (list price) adds £410 per year to standard VED rates for years 2-6 of registration. This surcharge brings the annual cost for high-emission vehicles over £40,000 to around £600-690 per year. Pure EVs under £40,000 pay zero VED.
